26 \enum Qt::AlignmentFlag
27
28 This enum type is used to describe alignment. It contains
29 horizontal and vertical flags that can be combined to produce
30 the required effect.
31
32 The \l{TextElideMode} enum can also be used in many situations
33 to fine-tune the appearance of aligned text.
34
35 The horizontal flags are:
36
37 \value AlignLeft Aligns with the left edge.
38 \value AlignRight Aligns with the right edge.
39 \value AlignHCenter Centers horizontally in the available space.
40 \value AlignJustify Justifies the text in the available space.
41
42 The vertical flags are:
43
44 \value AlignTop Aligns with the top.
45 \value AlignBottom Aligns with the bottom.
46 \value AlignVCenter Centers vertically in the available space.
47 \value AlignBaseline Aligns with the baseline.
48
49 You can use only one of the horizontal flags at a time. There is
50 one two-dimensional flag:
51
52 \value AlignCenter Centers in both dimensions.
53
54 You can use at most one horizontal and one vertical flag at a
55 time. Qt::AlignCenter counts as both horizontal and vertical.
56
57 Three enum values are useful in applications that can be run in
58 right-to-left mode:
59
60 \value AlignAbsolute If the widget's layout direction is
61 Qt::RightToLeft (instead of Qt::LeftToRight, the default),
62 Qt::AlignLeft refers to the \e right edge and Qt::AlignRight
63 to the \e left edge. This is normally the desired behavior.
64 If you want Qt::AlignLeft to always mean "left" and
65 Qt::AlignRight to always mean "right", combine the flag with
66 Qt::AlignAbsolute.
67 \value AlignLeading Synonym for Qt::AlignLeft.
68 \value AlignTrailing Synonym for Qt::AlignRight.
69
70 Masks:
71
72 \value AlignHorizontal_Mask
73 \value AlignVertical_Mask
74
75 Conflicting combinations of flags have undefined meanings.

79 \enum Qt::ApplicationAttribute
80
81 This enum describes attributes that change the behavior of
82 application-wide features. These are enabled and disabled using
83 QCoreApplication::setAttribute(), and can be tested for with
84 QCoreApplication::testAttribute().
85
86
87 \value [since 6.7] AA_QtQuickUseDefaultSizePolicy Qt Quick Layouts use the built-in size
88 policy of \l Item. For example, when this is set, \l Button fills the available
89 width, but has a fixed height. When this is not set, it will use the default
90 sizing behavior of the layout it's in, which is to use its implicit size as the
91 preferred size. This is explained in detail in \l {Specifying preferred size} and
92 \l {Size constraints}. When this is set, the default size policy of the item
93 with the layout can be overridden by explicitly setting
94 \l{Layout::fillWidth}{Layout.fillWidth} or
95 \l{Layout::fillHeight}{Layout.fillHeight}.
96
97 \value AA_DontShowIconsInMenus Actions with the Icon property won't be
98 shown in any menus unless specifically set by the
99 QAction::iconVisibleInMenu property. The default value of this
100 attribute depends on the platform. To override the default
101 behavior, set the attribute after QGuiApplication has been
102 instantiated.
103 Menus that are currently open or menus already created in the native
104 \macos menubar \e{may not} pick up a change in this attribute. Changes
105 in the QAction::iconVisibleInMenu property will always be picked up.
106
107 \value AA_DontShowShortcutsInContextMenus Actions with the Shortcut property
108 won't be shown in any shortcut menus unless specifically set by the
109 QAction::shortcutVisibleInContextMenu property. This value was added
110 in Qt 5.10, and is by default based on the value reported by
111 QStyleHints::showShortcutsInContextMenus(). To override the default
112 behavior, set the style hint before QCoreApplication has been
113 instantiated, or set this attribute after QCoreApplication has
114 been instantiated.
115
116 \value AA_NativeWindows Ensures that widgets have native windows.
117
118 \value AA_DontCreateNativeWidgetSiblings Ensures that siblings of native
119 widgets stay non-native unless specifically set by the
120 Qt::WA_NativeWindow attribute.
121
122 \value AA_PluginApplication Indicates that Qt is used to author a plugin. Depending
123 on the operating system, it suppresses specific initializations that do not
124 necessarily make sense in the plugin case.
125 For example on \macos, this includes avoiding loading our nib for the main
126 menu and not taking possession of the native menu bar. Setting this
127 attribute to true will also set the AA_DontUseNativeMenuBar attribute
128 to true. It also disables native event filters.
129 This attribute must be set before QGuiApplication constructed.
130 This value was added in Qt 5.7.
131
132 \value AA_DontUseNativeMenuBar All menubars created while this attribute is
133 set to true won't be used as a native menubar (e.g, the menubar at
134 the top of the main screen on \macos).
135
136 \value AA_MacDontSwapCtrlAndMeta Keyboard shortcuts on Apple platforms are typically
137 based on the Command (or Cmd) keyboard modifier, represented by
138 the ⌘ symbol. For example, the 'Copy' action is Command+C (⌘+C).
139 To ease cross platform development Qt will by default remap Command
140 to the Qt::ControlModifier, to align with other platforms. This
141 allows creating keyboard shortcuts such as "Ctrl+J", which on
142 \macos will then map to Command+J, as expected by \macos users. The
143 actual Control (or Ctrl) modifier on Apple platforms, represented by ⌃,
144 is mapped to Qt::MetaModifier.
145
146 When this attribute is true Qt will not do the remapping, and pressing
147 the Command modifier will result in Qt::MetaModifier, while pressing
148 the Control modifier will result in Qt::ControlModifier.
149
150 Note that the \l QKeySequence::StandardKey sequences will always be
151 based on the same modifier (i.e., QKeySequence::Copy will be
152 Command+C regardless of the value set), but what is output for
153 QKeySequence::toString() will be different.
154
155 \value AA_Use96Dpi Assume the screen has a resolution of 96 DPI rather
156 than using the OS-provided resolution. This will cause font rendering
157 to be consistent in pixels-per-point across devices rather than
158 defining 1 point as 1/72 inch.
159
160 \value AA_SynthesizeTouchForUnhandledMouseEvents All mouse events
161 that are not accepted by the application will be translated
162 to touch events instead.
163
164 \value AA_SynthesizeMouseForUnhandledTouchEvents All touch events
165 that are not accepted by the application will be translated
166 to left button mouse events instead. This attribute is enabled
167 by default.
168
169 \value AA_ForceRasterWidgets Make top-level widgets use pure raster surfaces,
170 and do not support non-native GL-based child widgets.
171
172 \value AA_UseDesktopOpenGL Forces the usage of desktop OpenGL (for example,
173 \e opengl32.dll or \e libGL.so) on platforms that use dynamic loading
174 of the OpenGL implementation. This attribute must be set before
175 QGuiApplication is constructed.
176 This value was added in Qt 5.3.
177
178 \value AA_UseOpenGLES Forces the usage of OpenGL ES 2.0 or higher on
179 platforms that use dynamic loading of the OpenGL implementation.
180 This attribute must be set before QGuiApplication is constructed.
181 This value was added in Qt 5.3.
182
183 \value AA_UseSoftwareOpenGL Forces the usage of a software based OpenGL
184 implementation on platforms that use dynamic loading of the OpenGL
185 implementation. This will typically be a patched build of
186 \l{http://www.mesa3d.org/llvmpipe.html}{Mesa llvmpipe}, providing
187 OpenGL 2.1. The value may have no effect if no such OpenGL
188 implementation is available. The default name of this library is
189 \c opengl32sw.dll and can be overridden by setting the environment
190 variable \e QT_OPENGL_DLL. See the platform-specific pages, for
191 instance \l{Qt for Windows}, for more information. This attribute
192 must be set before QGuiApplication is constructed.
193 This value was added in Qt 5.4.
194
195 \value AA_ShareOpenGLContexts Enables resource sharing between the OpenGL
196 contexts used by classes like QOpenGLWidget and QQuickWidget. This
197 allows sharing OpenGL resources, like textures, between QOpenGLWidget
198 instances that belong to different top-level windows.
199 This value was added in Qt 5.4.
200
201 \value AA_SetPalette Indicates whether a palette was explicitly set on the
202 QGuiApplication. This value was added in Qt 5.5.
203
204 \value AA_UseStyleSheetPropagationInWidgetStyles By default, Qt Style Sheets
205 disable regular QWidget palette and font propagation. When this flag
206 is enabled, font and palette changes done from a style sheet will propagate
207 a single time, when the style sheet is set.
208 See \l{The Style Sheet Syntax#Inheritance}{The Style Sheet Syntax - Inheritance}
209 for more details.
210 This value was added in Qt 5.7.
211
212 \value AA_DontUseNativeDialogs All dialogs created while this attribute is
213 set to true won't use the native dialogs provided by the platform.
214 This value was added in Qt 5.7.
215
216 \value AA_SynthesizeMouseForUnhandledTabletEvents All tablet events
217 that are not accepted by the application will be translated
218 to mouse events instead. This attribute is enabled
219 by default.
220 This value was added in Qt 5.7.
221
222 \value AA_CompressHighFrequencyEvents Enables compression of certain frequent events.
223 On the X11 windowing system, the default value is true, which means that
224 QEvent::MouseMove, QEvent::TouchUpdate, and changes in window size and
225 position will be combined whenever they occur more frequently than the
226 application handles them, so that they don't accumulate and overwhelm the
227 application later.
228 On Windows 8 and above the default value is also true, but it only applies
229 to touch events. Mouse and window events remain unaffected by this flag.
230 On Wayland the default value is also true, but it only applies to mouse events.
231 On other platforms, the default is false.
232 (In the future, the compression feature may be implemented across platforms.)
233 You can test the attribute to see whether compression is enabled.
234 If your application needs to handle all events with no compression,
235 you can unset this attribute. Notice that input events from tablet devices
236 will not be compressed. See AA_CompressTabletEvents if you want these to be
237 compressed as well.
238 This value was added in Qt 5.7.
239
240 \value AA_CompressTabletEvents Enables compression of input events from tablet devices.
241 Notice that AA_CompressHighFrequencyEvents must be true for events compression
242 to be enabled, and that this flag extends the former to tablet events.
243 Currently supported on the X11 windowing system, Windows 8 and above.
244 The default value is false.
245 This value was added in Qt 5.10.
246
247 \value AA_DontCheckOpenGLContextThreadAffinity When making a context
248 current using QOpenGLContext, do not check that the
249 \l{QObject#Thread Affinity}{QObject thread affinity}
250 of the QOpenGLContext object is the same thread calling
251 \l{QOpenGLContext::makeCurrent}{makeCurrent()}.
252 This value was added in Qt 5.8.
253
254 \value AA_DisableShaderDiskCache Disables caching of shader program binaries
255 on disk. By default Qt Quick, QPainter's OpenGL backend, and any
256 application using QOpenGLShaderProgram with one of its
257 \e addCacheableShaderFromSource overloads will employ a disk-based
258 program binary cache in either the shared or per-process cache storage
259 location, on systems that support \e glProgramBinary(). In the unlikely
260 event of this being problematic, set this attribute to disable all
261 disk-based caching of shaders.
262
263 \value AA_DisableSessionManager Disables the QSessionManager.
264 By default Qt will connect to a running session manager for a GUI
265 application on supported platforms, use of a session manager may be
266 redundant for system services.
267 This attribute must be set before QGuiApplication is constructed.
268 This value was added in 5.14
269
270 \value AA_DisableNativeVirtualKeyboard When this attribute is set, the native
271 on-screen virtual keyboard will not be shown automatically when a
272 text input widget gains focus on a system without a physical keyboard.
273 Currently supported on the Windows platform only.
274 This value was added in 5.15
275
276 \value AA_DontUseNativeMenuWindows Menu popup windows (e.g. context menus,
277 combo box menus, and non-native menubar menus) created while this
278 attribute is set to true will not be represented as native top
279 level windows, unless required by the implementation.
280 This value was added in Qt 6.8.

566 one line.
567 \value TextDontClip If it's impossible to stay within the given bounds,

569 \value TextExpandTabs Makes the U+0009 (ASCII tab) character move to
570 the next tab stop.
571 \value TextShowMnemonic Displays the string "\&P" as \underline{P}
572 For an ampersand, use "\&\&".
573 \value TextWordWrap Breaks lines at appropriate points, e.g. at word
574 boundaries.
575 \value TextWrapAnywhere Breaks lines anywhere, even within words.
576 \value TextHideMnemonic Same as Qt::TextShowMnemonic but doesn't draw
577 the underlines.
578 \value TextDontPrint Treat this text as "hidden" and don't print it.
579 \value TextIncludeTrailingSpaces When this option is set,
580 QTextLine::naturalTextWidth() and QTextLine::naturalTextRect() will
581 return a value that includes the width of trailing spaces in the
582 text; otherwise this width is excluded.

606 \enum Qt::ConnectionType
607
608 This enum describes the types of connection that can be used
609 between signals and slots. In particular, it determines whether a
610 particular signal is delivered to a slot immediately or queued for
611 delivery at a later time.
612
613 \value AutoConnection
614 \b (Default) If the receiver \l{QObject#Thread Affinity}{lives in} the
615 thread that emits the signal, Qt::DirectConnection is used. Otherwise,
616 Qt::QueuedConnection is used. The connection type is
617 determined when the signal is emitted.
618
619 \value DirectConnection
620 The slot is invoked immediately when the signal is
621 emitted. The slot is executed in the signalling thread.
622
623 \value QueuedConnection
624 The slot is invoked when control returns to the event loop
625 of the receiver's thread. The slot is executed in the
626 receiver's thread.
627
628 \value BlockingQueuedConnection
629 Same as Qt::QueuedConnection, except that the signalling thread blocks
630 until the slot returns. This connection must \e not be used if the
631 receiver lives in the signalling thread, or else the application
632 will deadlock.
633
634 \value UniqueConnection
635 This is a flag that can be combined with any one of the above
636 connection types, using a bitwise OR. When Qt::UniqueConnection is
637 set, QObject::connect() will fail if the connection already exists
638 (i.e. if the same signal is already connected to the same slot
639 for the same pair of objects).
640
641 \value SingleShotConnection
642 This is a flag that can be combined with any one of the above
643 connection types, using a bitwise OR. When Qt::SingleShotConnection
644 is set, the slot is going to be called only once; the connection
645 will be automatically broken when the signal is emitted.
646 This flag was introduced in Qt 6.0.
647
648 With queued connections, the parameters must be of types that are
649 known to Qt's meta-object system, because Qt needs to copy the
650 arguments to store them in an event behind the scenes. If you try
651 to use a queued connection and get the error message:
652
653 \snippet code/doc_src_qnamespace.qdoc 0
654
655 Call qRegisterMetaType() to register the data type before you
656 establish the connection.

664 \enum Qt::DateFormat
665
666 \value TextDate The default Qt format, which includes the day and month
667 name, the day number in the month, and the year in full. The day and month
668 names will be short names in English (C locale). This effectively uses, for
669 a date, format \c{ddd MMM d yyyy}, for a time \c{HH:mm:ss} and combines
670 these as \c{ddd MMM d HH:mm:ss yyyy} for a date-time, with an optional
671 zone-offset suffix, where relevant. When reading from a string, a
672 fractional part is also recognized on the seconds of a time part, as
673 \c{HH:mm:ss.zzz}, and some minor variants on the format may be recognized,
674 for compatibility with earlier versions of Qt and with changes to the format
675 planned for the future. In particular, the zone-offset suffix presently uses
676 \c{GMT[±tzoff]} with a \c{tzoff} in \c{HH[[:]mm]} format (two-digit hour and
677 optional two-digit minutes, with optional colon separator); this shall
678 change to use \c{UTC} in place of \c{GMT} in a future release of Qt, so the
679 planned \c{UTC} format is recognized.
680
681 \value ISODateWithMs \l{ISO 8601} extended format: uses \c{yyyy-MM-dd} for
682 dates, \c{HH:mm:ss.zzz} for times or \c{yyyy-MM-ddTHH:mm:ss.zzz}
683 (e.g. 2017-07-24T15:46:29.739) for combined dates and times, optionally with
684 a time-zone suffix (Z for UTC otherwise an offset as ±HH:mm) where
685 appropriate. When parsed, a single space, \c{' '}, may be used in place of
686 the \c{'T'} separator between date and time; no other spacing characters are
687 permitted. This format also accepts \c{HH:mm} and plain \c{HH} formats for
688 the time part, either of which may include a fractional part, \c{HH:mm.zzz}
689 or \c{HH.zzz}, applied to the last field present (hour or minute).
690
691 \value ISODate \l{ISO 8601} extended format, as for \c ISODateWithMs, but
692 omitting the milliseconds (\c{.zzz}) part when converting to a string. There
693 is no difference when reading from a string: if a fractional part is present
694 on the last time field, either format will accept it.
695
696 \value RFC2822Date \l{RFC 2822}, \l{RFC 850} and \l{RFC 1036} format: when
697 converting dates to string form, format \c{dd MMM yyyy} is used, for times
698 the format is \c{HH:mm:ss}. For combined date and time, these are combined
699 as \c{dd MMM yyyy HH:mm:ss ±tzoff} (omitting the optional leading day of the
700 week from the first format recognized). When reading from a string either
701 \c{[ddd,] dd MMM yyyy [HH:mm[:ss]][ ±tzoff]} or \c{ddd MMM dd[ HH:mm:ss]
702 yyyy[ ±tzoff]} will be recognized for combined dates and times, where
703 \c{tzoff} is a timezone offset in \c{HHmm} format. Arbitrary spacing may
704 appear before or after the text and any non-empty spacing may replace the
705 spaces in this format. For dates and times separately, the same formats are
706 matched and the unwanted parts are ignored. In particular, note that a time
707 is not recognized without an accompanying date.
708
709 \note For \c ISODate formats, each \c y, \c M and \c d represents a single
710 digit of the year, month, and day used to specify the date. Each \c H, \c m,
711 and \c s represents a single digit of the hour (up to 24), minute and second
712 used to specify the time. An hour of 24, with zero for all other time
713 fields, is understood as the start of the next day. A \c{.zzz} stands for a
714 fractional part suffix on the preceding field, which may be separated from
715 that field either by a comma \c{','} or the dot \c{'.'} shown. Precision
716 beyond milliseconds is accepted but discarded, rounding to the nearest
717 representable millisecond. The presence of a literal \c T character is used
718 to separate the date and time when both are specified. For the \c TextDate
719 and \c RFC2822Date formats, \c{ddd} stands for the first three letters of
720 the name of the day of the week and \c{MMM} stands for the first three
721 letters of the month name. The names of days and months are always in
722 English (C locale) regardless of user preferences or system settings. The
723 other format characters have the same meaning as for the ISODate format,
724 except that 24 is not accepted as an hour. Parts of a format enclosed in
725 square brackets \c{[...]} are optional; the square brackets do not form part
726 of the format. The plus-or-minus character \c{'±'} here stands for either
727 sign character, \c{'-'} for minus or \c{'+'} for plus.
728
729 \note Zone offsets are measured positive to the east of Greenwich, negative
730 to the west, as is usual for UTC-based offset notations (conflicting with
731 some GMT-based zones-names, such as \c{Etc/GMT+3}, which use the opposite
732 convention).

744 \value TimeZone A named time zone.
745
746 Both LocalTime and TimeZone will take care of transitions, such as
747 the start and end of daylight-saving time. UTC is the standard
748 time relative to which time-zones are usually specified: Greenwich
749 Mean Time has zero offset from it. Neither UTC nor OffsetFromUTC
750 has any transitions.
751
752 When specifying a datetime using OffsetFromUTC, the offset from UTC must
753 also be supplied (it is measured in seconds). To specify a datetime using
754 TimeZone, a QTimeZone must be supplied. From Qt 6.5, a QTimeZone can now
755 package a timespec with, where needed, an offset as a lightweight time
756 description, so that passing a QTimeZone now provides a uniform way to use
757 datetime APIs, saving the need to call them differently for different
758 timespecs.
759
760 \note After a change to the system time-zone setting, the behavior
761 of LocalTime-based QDateTime objects created before the change is
762 undefined: QDateTime may have cached data that the change

767 information and data cached by QDateTime objects created before

1011 not a part of the viewable Desktop.
1012
1013 \value WA_ForceDisabled Indicates that the widget is
1014 explicitly disabled, i.e. it will remain disabled even when all
1015 its ancestors are set to the enabled state. This implies
1016 WA_Disabled. This is set/cleared by QWidget::setEnabled() and

1032 \value WA_KeyboardFocusChange Set on a toplevel window when
1033 the users changes focus with the keyboard (tab, backtab, or shortcut).
1034
1035 \value WA_KeyCompression Enables key event compression if set,
1036 and disables it if not set. By default key compression is off, so
1037 widgets receive one key press event for each key press (or more,
1038 since autorepeat is usually on). If you turn it on and your
1039 program doesn't keep up with key input, Qt may try to compress key
1040 events so that more than one character can be processed in each
1041 event.
1042 For example, a word processor widget might receive 2, 3 or more
1043 characters in each QKeyEvent::text(), if the layout recalculation
1044 takes too long for the CPU.
1045 If a widget supports multiple character unicode input, it is
1046 always safe to turn the compression on.
1047 Qt performs key event compression only for printable characters.
1048 Qt::Modifier keys, cursor movement keys, function keys and
1049 miscellaneous action keys (e.g. Escape, Enter, Backspace,
1050 PrintScreen) will stop key event compression, even if there are
1051 more compressible key events available.
1052 Platforms other than Mac and X11 do not support this compression,
1053 in which case turning it on will have no effect.
1054 This is set/cleared by the widget's author.
1055
1056 \value WA_LayoutOnEntireRect Indicates that the widget
1057 wants QLayout to operate on the entire QWidget::rect(), not only
1058 on QWidget::contentsRect(). This is set by the widget's author.
1059
1060 \value WA_LayoutUsesWidgetRect Ignore the layout item rect from the style
1061 when laying out this widget with QLayout.
1062
1063 \value WA_MacOpaqueSizeGrip Indicates that the native size grip
1064 should be opaque instead of transparent (the default). This attribute
1065 is only applicable to \macos and is set by the widget's author.
1066
1067 \value WA_MacShowFocusRect Indicates that this widget should get a
1068 QFocusFrame around it. Some widgets draw their own focus halo
1069 regardless of this attribute. Not that the QWidget::focusPolicy
1070 also plays the main role in whether something is given focus or
1071 not, this only controls whether or not this gets the focus
1072 frame. This attribute is only applicable to \macos.
1073

1080 \macos.
1081
1082 \value WA_MacMiniSize Indicates the widget should have the mini
1083 size for widgets in \macos. This attribute is only applicable to
1084 \macos.
1085
1086 \value WA_Mapped Indicates that the widget is mapped on screen.
1087 This is set/cleared by the Qt kernel.
1088
1089 \value WA_MouseNoMask Makes the widget receive mouse events for
1090 the entire widget regardless of the currently set mask,
1091 overriding QWidget::setMask(). This is not applicable for
1092 top-level windows.
1093
1094 \value WA_MouseTracking Indicates that the widget has mouse
1095 tracking enabled. See QWidget::mouseTracking.
1096
1097 \value WA_Moved Indicates that the widget has an explicit
1098 position. This is set/cleared by QWidget::move() and
1099 by QWidget::setGeometry().
1100
1101 \value WA_NoChildEventsForParent Indicates that the widget does
1102 not want \l{QEvent::}{ChildAdded} or \l{QEvent::}{ChildRemoved} events sent to its
1103 parent. This is rarely necessary but can help to avoid automatic
1104 insertion widgets like splitters and layouts. This is set by a
1105 widget's author.
1106
1107 \value WA_NoChildEventsFromChildren Indicates that the widget does
1108 not want to receive \l{QEvent::}{ChildAdded} or \l{QEvent::}{ChildRemoved} events sent from its
1109 children. This is set by a widget's author.
1110
1111 \value WA_NoMouseReplay Used for pop-up widgets. Indicates that the most
1112 recent mouse press event should not be replayed when the pop-up widget
1113 closes. The flag is set by the widget's author and cleared by the Qt kernel
1114 every time the widget receives a new mouse event.
1115
1116 \value WA_NoMousePropagation Prohibits mouse events from being propagated
1117 to the widget's parent. This attribute is disabled by default.
1118
1119 \value WA_TransparentForMouseEvents When enabled, this attribute disables
1120 the delivery of mouse events to the widget and its children. Mouse events
1121 are delivered to other widgets as if the widget and its children were not
1122 present in the widget hierarchy; mouse clicks and other events effectively
1123 "pass through" them. This attribute is disabled by default.
1124
1125 \value WA_NoSystemBackground Indicates that the widget has no background,
1126 i.e. when the widget receives paint events, the background is not
1127 automatically repainted. \b Note: Unlike WA_OpaquePaintEvent, newly exposed
1128 areas are \b never filled with the background (e.g., after showing a
1129 window for the first time the user can see "through" it until the
1130 application processes the paint events). This flag is set or cleared by the
1131 widget's author.
1132
1133 \value WA_OpaquePaintEvent Indicates that the widget paints all its pixels
1134 when it receives a paint event. Thus, it is not required for operations
1135 like updating, resizing, scrolling and focus changes to erase the widget
1136 before generating paint events. The use of WA_OpaquePaintEvent provides a
1137 small optimization by helping to reduce flicker on systems that do not
1138 support double buffering and avoiding computational cycles necessary to
1139 erase the background prior to painting. \b Note: Unlike
1140 WA_NoSystemBackground, WA_OpaquePaintEvent makes an effort to avoid
1141 transparent window backgrounds. This flag is set or cleared by the widget's
1142 author.
1143
1144 \value WA_OutsideWSRange Indicates that the widget is outside
1145 the valid range of the window system's coordinate system. A widget
1146 outside the valid range cannot be mapped on screen. This is
1147 set/cleared by the Qt kernel.
1148
1149 \value WA_PaintOnScreen Indicates that the widget wants to draw directly
1150 onto the screen. Widgets with this attribute set do not participate in
1151 composition management, i.e. they cannot be semi-transparent or shine
1152 through semi-transparent overlapping widgets. \b Note: This flag is only
1153 supported on X11 and it disables double buffering. On Qt for Embedded
1154 Linux, the flag only works when set on a top-level widget and it relies on
1155 support from the active screen driver. This flag is set or cleared by the
1156 widget's author. To render outside of Qt's paint system, e.g., if you
1157 require native painting primitives, you need to reimplement
1158 QWidget::paintEngine() to return 0 and set this flag.
1159
1160 \value WA_PaintUnclipped Makes all painters operating on this widget
1161 unclipped. Children of this widget or other widgets in front of it do not
1162 clip the area the painter can paint on. This flag is only supported for
1163 widgets with the WA_PaintOnScreen flag set. The preferred way to do this in
1164 a cross platform way is to create a transparent widget that lies in front
1165 of the other widgets.
1166
1167 \value WA_PendingMoveEvent Indicates that a move event is pending, e.g.,
1168 when a hidden widget was moved. This flag is set or cleared by the Qt
1169 kernel.
1170
1171 \value WA_PendingResizeEvent Indicates that a resize event is pending,
1172 e.g., when a hidden widget was resized. This flag is set or cleared by the
1173 Qt kernel.
1174
1175 \value WA_QuitOnClose Indicates that the widget should be taken into account
1176 when deciding whether to quit the application when the last window is closed.
1177 This behavior can be modified with the QGuiApplication::quitOnLastWindowClosed
1178 property. By default this attribute is set for all widgets of type Qt::Window.
1179
1180 \value WA_Resized Indicates that the widget has an explicit size. This flag
1181 is set or cleared by QWidget::resize() and QWidget::setGeometry().
1182
1183 \value WA_RightToLeft Indicates that the layout direction for the widget
1184 is right to left.
1185
1186 \value WA_SetCursor Indicates that the widget has a cursor of its own. This
1187 flag is set or cleared by QWidget::setCursor() and QWidget::unsetCursor().
1188
1189 \value WA_SetFont Indicates that the widget has a font of its own. This
1190 flag is set or cleared by QWidget::setFont().
1191
1192 \value WA_SetPalette Indicates that the widget has a palette of its own.
1193 This flag is set or cleared by QWidget::setPalette().
1194
1195 \value WA_SetStyle Indicates that the widget has a style of its own. This
1196 flag is set or cleared by QWidget::setStyle().
1197
1198 \value WA_ShowModal \e{This attribute has been deprecated.} Use
1199 QWidget::windowModality instead.
1200
1201 \value WA_StaticContents Indicates that the widget contents are north-west
1202 aligned and static. On resize, such a widget will receive paint events only
1203 for parts of itself that are newly visible. This flag is set or cleared by
1204 the widget's author.
1205
1206 \value WA_StyleSheet Indicates that the widget is styled using a
1207 \l{Qt Style Sheets}{style sheet}. WA_StyleSheet is set whenever a widget
1208 is subject to a style sheet, even if the style sheet did not affect the
1209 widget appearance.
1210
1211 \value WA_StyleSheetTarget Indicates that the widget appearance was modified
1212 by a \l{Qt Style Sheets}{style sheet}. WA_StyleSheet will also be set.
1213 This value was introduced in Qt 5.12.
1214
1215 \value WA_TabletTracking Indicates that the widget has tablet
1216 tracking enabled. See QWidget::tabletTracking.
1217
1218 \value WA_TranslucentBackground Indicates that the widget should have a
1219 translucent background, i.e., any non-opaque regions of the widgets will be
1220 translucent because the widget will have an alpha channel. Setting this
1221 flag causes WA_NoSystemBackground to be set. On Windows the widget also
1222 needs the Qt::FramelessWindowHint window flag to be set. This flag is set
1223 or cleared by the widget's author. As of Qt 5.0, toggling this attribute
1224 after the widget has been shown is not uniformly supported across
1225 platforms. When translucent background is desired, set the attribute early
1226 when creating the widget, and avoid altering it afterwards.
1227
1228 \value WA_UnderMouse Indicates that the widget is under the mouse cursor.
1229 The value is not updated correctly during drag and drop operations. There
1230 is also a getter function, QWidget::underMouse(). This flag is set or
1231 cleared by the Qt kernel.
1232
1233 \value WA_UpdatesDisabled Indicates that updates are blocked (including the
1234 system background). This flag is set or cleared by the Qt kernel.
1235 \b Warning: This flag must \e never be set or cleared by the widget's author.
1236
1237 \value WA_WindowModified Indicates that the window is marked as modified.
1238 On some platforms this flag will do nothing, on others (including \macos
1239 and Windows) the window will take a modified appearance. This flag is set
1240 or cleared by QWidget::setWindowModified().
1241
1242 \value WA_WindowPropagation Makes a toplevel window inherit font, palette
1243 and locale from its parent.
1244
1245 \value WA_MacAlwaysShowToolWindow On \macos, show the tool window even
1246 when the application is not active. By default, all tool windows are
1247 hidden when the application is inactive.
1248
1249 \value WA_SetLocale Indicates the locale should be taken into consideration
1250 in the widget.
1251
1252 \value WA_StyledBackground Indicates the widget should be drawn using a
1253 styled background.
1254
1255 \value WA_ShowWithoutActivating Show the widget without making it active.
1256
1257 \value WA_NativeWindow Indicates that a native window is created for the
1258 widget. Enabling this flag will also force a native window for the widget's
1259 ancestors unless Qt::WA_DontCreateNativeAncestors is set.
1260
1261 \value WA_DontCreateNativeAncestors Indicates that the widget's ancestors
1262 are kept non-native even though the widget itself is native.
1263
1264 \value WA_X11NetWmWindowTypeDesktop Adds _NET_WM_WINDOW_TYPE_DESKTOP to the
1265 window's _NET_WM_WINDOW_TYPE X11 window property. See
1266 http://standards.freedesktop.org/wm-spec/ for more details. This attribute
1267 has no effect on non-X11 platforms.
1268
1269 \value WA_X11NetWmWindowTypeDock Adds _NET_WM_WINDOW_TYPE_DOCK to the
1270 window's _NET_WM_WINDOW_TYPE X11 window property. See
1271 http://standards.freedesktop.org/wm-spec/ for more details. This attribute
1272 has no effect on non-X11 platforms.
1273
1274 \value WA_X11NetWmWindowTypeToolBar Adds _NET_WM_WINDOW_TYPE_TOOLBAR to the
1275 window's _NET_WM_WINDOW_TYPE X11 window property. See
1276 http://standards.freedesktop.org/wm-spec/ for more details. This attribute
1277 has no effect on non-X11 platforms. \b Note: Qt automatically sets this
1278 attribute for QToolBar.
1279
1280 \value WA_X11NetWmWindowTypeMenu Adds _NET_WM_WINDOW_TYPE_MENU to the
1281 window's _NET_WM_WINDOW_TYPE X11 window property. See
1282 http://standards.freedesktop.org/wm-spec/ for more details. This attribute
1283 has no effect on non-X11 platforms. \b Note: Qt automatically sets this
1284 attribute for QMenu when torn-off.
1285
1286 \value WA_X11NetWmWindowTypeUtility Adds _NET_WM_WINDOW_TYPE_UTILITY to the
1287 window's _NET_WM_WINDOW_TYPE X11 window property. See
1288 http://standards.freedesktop.org/wm-spec/ for more details. This attribute
1289 has no effect on non-X11 platforms. \b Note: Qt automatically sets this
1290 attribute for the Qt::Tool window type.
1291
1292 \value WA_X11NetWmWindowTypeSplash Adds _NET_WM_WINDOW_TYPE_SPLASH to the
1293 window's _NET_WM_WINDOW_TYPE X11 window property. See
1294 http://standards.freedesktop.org/wm-spec/ for more details. This attribute
1295 has no effect on non-X11 platforms. \b Note: Qt automatically sets this
1296 attribute for the Qt::SplashScreen window type.
1297
1298 \value WA_X11NetWmWindowTypeDialog Adds _NET_WM_WINDOW_TYPE_DIALOG
1299 to the window's _NET_WM_WINDOW_TYPE X11 window property. See
1300 http://standards.freedesktop.org/wm-spec/ for more details. This
1301 attribute has no effect on non-X11 platforms. \b Note: Qt automatically sets
1302 this attribute for the Qt::Dialog and Qt::Sheet window types.
1303
1304 \value WA_X11NetWmWindowTypeDropDownMenu Adds
1305 _NET_WM_WINDOW_TYPE_DROPDOWN_MENU to the window's
1306 _NET_WM_WINDOW_TYPE X11 window property. See
1307 http://standards.freedesktop.org/wm-spec/ for more details. This
1308 attribute has no effect on non-X11 platforms. \b Note: Qt
1309 automatically sets this attribute for QMenu objects added to a QMenuBar.
1310
1311 \value WA_X11NetWmWindowTypePopupMenu Adds _NET_WM_WINDOW_TYPE_POPUP_MENU
1312 to the window's _NET_WM_WINDOW_TYPE X11 window property. See
1313 http://standards.freedesktop.org/wm-spec/ for more details. This attribute
1314 has no effect on non-X11 platforms. \b Note: Qt automatically sets this
1315 attribute for QMenu.
1316
1317 \value WA_X11NetWmWindowTypeToolTip Adds _NET_WM_WINDOW_TYPE_TOOLTIP to the
1318 window's _NET_WM_WINDOW_TYPE X11 window property. See
1319 http://standards.freedesktop.org/wm-spec/ for more details. This attribute
1320 has no effect on non-X11 platforms. \b Note: Qt automatically sets this
1321 attribute for the Qt::ToolTip window type.
1322
1323 \value WA_X11NetWmWindowTypeNotification Adds
1324 _NET_WM_WINDOW_TYPE_NOTIFICATION to the window's _NET_WM_WINDOW_TYPE X11
1325 window property. See http://standards.freedesktop.org/wm-spec/ for more
1326 details. This attribute has no effect on non-X11 platforms.
1327
1328 \value WA_X11NetWmWindowTypeCombo Adds _NET_WM_WINDOW_TYPE_COMBO
1329 to the window's _NET_WM_WINDOW_TYPE X11 window property. See
1330 http://standards.freedesktop.org/wm-spec/ for more details. This attribute
1331 has no effect on non-X11 platforms. \b Note: Qt automatically sets this
1332 attribute for the QComboBox pop-up.
1333
1334 \value WA_X11NetWmWindowTypeDND Adds _NET_WM_WINDOW_TYPE_DND to
1335 the window's _NET_WM_WINDOW_TYPE X11 window property. See
1336 http://standards.freedesktop.org/wm-spec/ for more details. This attribute
1337 has no effect on non-X11 platforms. \b Note: Qt automatically sets this
1338 attribute on the feedback widget used during a drag.
1339
1340 \value WA_AcceptTouchEvents Allows touch events (see QTouchEvent)
1341 to be sent to the widget. Must be set on all widgets that can
1342 handle touch events. Without this attribute set, events from a
1343 touch device will be sent as mouse events.
1344
1345 \value WA_TouchPadAcceptSingleTouchEvents Allows touchpad single
1346 touch events to be sent to the widget.
1347
1348 \value WA_X11DoNotAcceptFocus Asks the window manager to not give focus
1349 to this top level window. This attribute has no effect on non-X11
1350 platforms.
1351
1352 \value [since 5.4] WA_AlwaysStackOnTop Forces QOpenGLWidget and
1353 QQuickWidget to be drawn last, on top of other widgets. Ignored for other
1354 type of widgets. Setting this attribute breaks the stacking order, but
1355 allows having a semi-transparent OpenGL widget with other widgets visible
1356 underneath. It is strongly recommended to call \l{QWidget::}{update()} on the widget's
1357 top-level window after enabling or disabling this attribute.
1358
1359 \value WA_ContentsMarginsRespectsSafeArea A QWidget respects the safe
1360 area margins of a window by incorporating the margins into its contents'
1361 margins by default. This means, that a QLayout will use the content area
1362 of a widget for its layout, unless the Qt::WA_LayoutOnEntireRect attribute
1363 is set. This along with a contents margin of 0 can be used on the actual
1364 layout, to allow for example a background image to underlay the status bar and other
1365 system areas on an iOS device, while still allowing child widgets of
1366 that background to be inset based on the safe area.

2174 \enum Qt::WindowType
2175
2176 \keyword window flag
2177
2178 This enum type is used to specify various window-system properties
2179 for the widget. They are fairly unusual but necessary in a few
2180 cases. Some of these flags depend on whether the underlying window
2181 manager supports them.
2182
2183 The main types are
2184
2185 \value Widget This is the default type for QWidget. Widgets of
2186 this type are child widgets if they have a parent,
2187 and independent windows if they have no parent.
2188 See also Qt::Window and Qt::SubWindow.
2189
2190 \value Window Indicates that the widget is a window, usually
2191 with a window system frame and a title bar,
2192 irrespective of whether the widget has a parent or
2193 not. Note that it is not possible to unset this
2194 flag if the widget does not have a parent.
2195
2196 \value Dialog Indicates that the widget is a window that should
2197 be decorated as a dialog (i.e., typically no
2198 maximize or minimize buttons in the title bar).
2199 This is the default type for QDialog. If you want
2200 to use it as a modal dialog, it should be launched
2201 from another window, or have a parent and used
2202 with the QWidget::windowModality property. If you make
2203 it modal, the dialog will prevent other top-level
2204 windows in the application from getting any input.
2205 We refer to a top-level window that has a parent
2206 as a \e secondary window.
2207
2208 \value Sheet Indicates that the window is a sheet on \macos. Since
2209 using a sheet implies window modality, the recommended
2210 way is to use QWidget::setWindowModality(), or
2211 QDialog::open(), instead.
2212
2213 \value Drawer Indicates that the widget is a drawer on \macos.
2214 This feature is obsolete. Setting the flag
2215 has no effect.
2216
2217 \value Popup Indicates that the widget is a pop-up top-level
2218 window, i.e. that it is modal, but has a window
2219 system frame appropriate for pop-up menus.
2220
2221 \value Tool Indicates that the widget is a tool window. A tool
2222 window is often a small window with a smaller than
2223 usual title bar and decoration, typically used for
2224 collections of tool buttons. If there is a parent,
2225 the tool window will always be kept on top of it.
2226 If there isn't a parent, you may consider using
2227 Qt::WindowStaysOnTopHint as well. If the window
2228 system supports it, a tool window can be decorated
2229 with a somewhat lighter frame. It can also be
2230 combined with Qt::FramelessWindowHint.
2231 On \macos, tool windows correspond to the
2232 \l{https://developer.apple.com/documentation/appkit/nspanel}{NSPanel}
2233 class of windows. This means that the window lives on a
2234 level above normal windows making it impossible to put a normal
2235 window on top of it. By default, tool windows will disappear
2236 when the application is inactive. This can be controlled by
2237 the Qt::WA_MacAlwaysShowToolWindow attribute.
2238
2239 \value ToolTip Indicates that the widget is a tooltip. This is
2240 used internally to implement
2241 \l{QWidget::toolTip}{tooltips}.
2242
2243 \value SplashScreen Indicates that the window is a splash screen.
2244 This is the default type for QSplashScreen.
2245
2246 \omitvalue Desktop Indicates that this widget is the desktop.
2247
2248 \value SubWindow Indicates that this widget is a sub-window, such
2249 as a QMdiSubWindow widget.
2250
2251 \value ForeignWindow Indicates that this window object is a handle
2252 representing a native platform window created by
2253 another process or by manually using native code.
2254
2255 \value CoverWindow Indicates that the window represents a cover window,
2256 which is shown when the application is minimized on
2257 some platforms.
2258
2259 There are also a number of flags which you can use to customize
2260 the appearance of top-level windows. These have no effect on other
2261 windows:
2262
2263 \value MSWindowsFixedSizeDialogHint Gives the window a thin dialog border on Windows.
2264 This style is traditionally used for fixed-size dialogs.
2265
2266 \note The use of this flag is not recommended in multi-monitor
2267 environments. This is because the system will enforce that the window
2268 maintains its native size when moving it across screens. This is
2269 particularly undesirable when using monitors with different
2270 resolutions.
2271
2272 \value MSWindowsOwnDC Gives the window its own display
2273 context on Windows.
2274
2275 \value BypassWindowManagerHint This flag can be used to indicate to the platform plugin
2276 that "all" window manager protocols should be disabled. This flag will behave
2277 different depending on what operating system the application is running on and
2278 what window manager is running. The flag can be used to get a native window
2279 with no configuration set.
2280
2281 \value X11BypassWindowManagerHint Bypass the window
2282 manager completely. This results in a borderless window
2283 that is not managed at all (i.e., no keyboard input unless
2284 you call QWidget::activateWindow() manually).
2285
2286 \value FramelessWindowHint Produces a borderless window.
2287
2288 On X11, the result of the flag is dependent on the window manager and its
2289 ability to understand Motif and/or NETWM hints. Most existing
2290 modern window managers can handle this.
2291
2292 \note If the window manager relies on the frame to interactively manipulate
2293 the window, the user can no longer move or resize the window via the window
2294 system, but this side effect should not be relied on. To produce a fixed
2295 size window that can not be resized, please set QWindow::setMinimumSize()
2296 and QWindow::setMaximumSize() to the same size.
2297
2298 \value NoDropShadowWindowHint Disables window drop shadow on supporting platforms.
2299
2300 The \c CustomizeWindowHint flag is used to enable customization of
2301 the window controls. This flag must be set to allow the \c
2302 WindowTitleHint, \c WindowSystemMenuHint, \c
2303 WindowMinimizeButtonHint, \c WindowMaximizeButtonHint and \c
2304 WindowCloseButtonHint flags to be changed.
2305
2306 \value CustomizeWindowHint Turns off the default window title hints.
2307
2308 \value WindowTitleHint Gives the window a title bar.
2309
2310 \value WindowSystemMenuHint Adds a window system menu, and
2311 possibly a close button (for example on Mac). If you need to hide
2312 or show a close button, it is more portable to use \c
2313 WindowCloseButtonHint.
2314
2315 \value WindowMinimizeButtonHint Adds a minimize button. On
2316 some platforms this implies Qt::WindowSystemMenuHint for it to work.
2317
2318 \value WindowMaximizeButtonHint Adds a maximize button. On
2319 some platforms this implies Qt::WindowSystemMenuHint for it to work.
2320
2321 \value WindowMinMaxButtonsHint Adds a minimize and a maximize
2322 button. On some platforms this implies Qt::WindowSystemMenuHint for it to work.
2323
2324 \value WindowCloseButtonHint Adds a close button. On
2325 some platforms this implies Qt::WindowSystemMenuHint for it
2326 to work.
2327
2328 \value WindowContextHelpButtonHint Adds a context help button to dialogs.
2329 On some platforms this implies Qt::WindowSystemMenuHint for it to work.
2330
2331 \omitvalue MacWindowToolBarButtonHint
2332
2333 \value WindowFullscreenButtonHint On \macos adds a fullscreen button.
2334
2335 \value BypassGraphicsProxyWidget Prevents the window and its children from
2336 automatically embedding themselves into a QGraphicsProxyWidget if the
2337 parent widget is already embedded. You can set this flag if you
2338 want your widget to always be a toplevel widget on the desktop,
2339 regardless of whether the parent widget is embedded in a scene or
2340 not.
2341
2342 \value WindowShadeButtonHint Adds a shade button in place of the minimize
2343 button if the underlying window manager supports it.
2344
2345 \value WindowStaysOnTopHint Informs the window system that the
2346 window should stay on top of all other windows. Note that
2347 on some window managers on X11 you also have to pass
2348 Qt::X11BypassWindowManagerHint for this flag to work
2349 correctly.
2350
2351 \value WindowStaysOnBottomHint Informs the window system that the
2352 window should stay on bottom of all other windows.
2353
2354 \note On X11, this hint will work only in window managers
2355 that support _NET_WM_STATE_BELOW atom. If a window always
2356 on the bottom has a parent, the parent will also be left on
2357 the bottom. This window hint is currently not implemented
2358 for \macos.
2359
2360 \note On Windows, this will work only for frameless or
2361 full-screen windows.
2362
2363 \value WindowTransparentForInput Informs the window system that this window
2364 is used only for output (displaying something) and does not take input.
2365 Therefore input events should pass through as if it wasn't there.
2366
2367 \value WindowOverridesSystemGestures Informs the window system that this window
2368 implements its own set of gestures and that system level gestures, like for
2369 instance three-finger desktop switching, should be disabled.
2370
2371 \value WindowDoesNotAcceptFocus Informs the window system that this window should
2372 not receive the input focus.
2373
2374 \note On Windows, this prevents the window from appearing in the taskbar.
2375
2376 \value MaximizeUsingFullscreenGeometryHint Deprecated alias for Qt::ExpandedClientAreaHint
2377
2378 \value [since 6.9] ExpandedClientAreaHint Requests that the window's client area is
2379 expanded to areas where it might be obscured by, or conflicting with other UI
2380 elements, such as the window's titlebar controls or other system UIs. The
2381 window's \l{QWindow::safeAreaMargins()}{safe area margins} will reflect any
2382 areas that may have conflicting UI elements.
2383
2384 \value [since 6.9] NoTitleBarBackgroundHint Requests that the window's title bar is drawn
2385 without a background color. This flag is useful in combination with
2386 Qt::ExpandedClientAreaHint, to give the perception that the window's
2387 client area seamlessly blends with the titlebar area and controls.
2388
2389 \value WindowType_Mask A mask for extracting the window type
2390 part of the window flags.

3269 \value CoarseTimer Coarse timers try to keep accuracy within 5% of the desired interval
3270 \value VeryCoarseTimer Very coarse timers only keep full second accuracy
3271
3272 On UNIX (including Linux, \macos, and iOS), Qt will keep millisecond accuracy
3273 for Qt::PreciseTimer. For Qt::CoarseTimer, the interval will be adjusted up
3274 to 5% to align the timer with other timers that are expected to fire at or
3275 around the same time. The objective is to make most timers wake up at the
3276 same time, thereby reducing CPU wakeups and power consumption.
3277
3278 On Windows, Qt will use Windows's Multimedia timer facility (if available)
3279 for Qt::PreciseTimer and normal Windows timers for Qt::CoarseTimer and
3280 Qt::VeryCoarseTimer.
3281
3282 On all platforms, the interval for Qt::VeryCoarseTimer is rounded to the
3283 nearest full second (e.g. an interval of 23500ms will be rounded to
3284 24000ms, and 20300ms to 20000ms).
