bool QQuickScrollBar::isActive | ( | ) | const |
\qmlproperty bool QtQuick.Controls::ScrollBar::active
This property holds whether the scroll bar is active, i.e. when it's \l pressed or the attached Flickable is \l {Flickable::moving}{moving}.
It is possible to keep \l {Binding the Active State of Horizontal and Vertical Scroll Bars} {both horizontal and vertical bars visible} while scrolling in either direction.
This property is automatically set when the scroll bar is \l {Attaching ScrollBar to a Flickable}{attached to a flickable}.
Definition at line 505 of file qquickscrollbar.cpp.
bool QQuickScrollBar::isHorizontal | ( | ) | const |
This property holds whether the scroll bar is horizontal.
Definition at line 707 of file qquickscrollbar.cpp.
bool QQuickScrollBar::isInteractive | ( | ) | const |
This property holds whether the scroll bar is interactive. The default value is true
.
A non-interactive scroll bar is visually and behaviorally similar to \l ScrollIndicator. This property is useful for switching between typical mouse- and touch-orientated UIs with interactive and non-interactive scroll bars, respectively.

bool QQuickScrollBar::isPressed | ( | ) | const |
\qmlproperty bool QtQuick.Controls::ScrollBar::pressed
This property holds whether the scroll bar is pressed.
Definition at line 526 of file qquickscrollbar.cpp.
bool QQuickScrollBar::isVertical | ( | ) | const |
This property holds whether the scroll bar is vertical.
Definition at line 722 of file qquickscrollbar.cpp.
qreal QQuickScrollBar::minimumSize | ( | ) | const |
This property holds the minimum size of the scroll bar, scaled to {0.0
- 1.0}.
Definition at line 736 of file qquickscrollbar.cpp.

overrideprotectedvirtual |
This event handler can be reimplemented in a subclass to receive mouse press events for an item.
The event information is provided by the event parameter.
In order to receive mouse press events, \l acceptedMouseButtons() must return the relevant mouse button.
\input item.qdocinc accepting-events
Reimplemented from QQuickControl.
Definition at line 834 of file qquickscrollbar.cpp.
Qt::Orientation QQuickScrollBar::orientation | ( | ) | const |
\qmlproperty enumeration QtQuick.Controls::ScrollBar::orientation
This property holds the orientation of the scroll bar.
Possible values: \value Qt.Horizontal Horizontal \value Qt.Vertical Vertical (default)
This property is automatically set when the scroll bar is \l {Attaching ScrollBar to a Flickable}{attached to a flickable}.
Definition at line 564 of file qquickscrollbar.cpp.
|
signal |
QQuickScrollBar::Policy QQuickScrollBar::policy | ( | ) | const |
This property holds the policy of the scroll bar. The default policy is ScrollBar.AsNeeded
.
Possible values: \value ScrollBar.AsNeeded The scroll bar is only shown when the content is too large to fit. \value ScrollBar.AlwaysOff The scroll bar is never shown. \value ScrollBar.AlwaysOn The scroll bar is always shown.
The following example keeps the vertical scroll bar always visible:
Styles may use this property in combination with the \l active property in order to implement transient scroll bars. Transient scroll bars are hidden shortly after the last interaction event (hover or press). This is typically done by animating the opacity of the scroll bar. To override this behavior, set the policy to ScrollBar.AlwaysOn
or ScrollBar.AlwaysOff
, depending on the size of the content compared to its view. For example, for a vertical \l ListView:
Definition at line 682 of file qquickscrollbar.cpp.
qreal QQuickScrollBar::position | ( | ) | const |
\qmlproperty real QtQuick.Controls::ScrollBar::position
This property holds the position of the scroll bar, scaled to {0.0
- 1.0}.
The largest valid scrollbar position is {
(1.0 - size)}. This gives correct behavior for the most used case where moving the scrollbar to the end will put the end of the document at the lower end of the visible area of the connected Flickable.
This property is automatically set when the scroll bar is \l {Attaching ScrollBar to a Flickable}{attached to a flickable}.

QQuickScrollBar::SnapMode QQuickScrollBar::snapMode | ( | ) | const |
This property holds the snap mode.
Possible values: \value ScrollBar.NoSnap The scrollbar does not snap (default). \value ScrollBar.SnapAlways The scrollbar snaps while dragged. \value ScrollBar.SnapOnRelease The scrollbar does not snap while being dragged, but only after released.
In the following table, the various modes are illustrated with animations. The movement and the \l stepSize (0.25
) are identical in each animation.
