\qmltype ColorGroup \nativetype QQuickColorGroup \inherits QtObject \inqmlmodule QtQuick
\internal \class QQuickColorGroup \brief The QQuickColorGroup class represents a set of colors. \inmodule QtQuick \since 6.0 Used by QQuickPalette to provide different groups of colors by roles. \sa QPalette::ColorRole
! internal
The set of colors by roles.
The ColorGroup type is used to define a set of colors with certain roles. Although a ColorGroup has no visual appearance, it defines colors used to customize rendered items.
Default values of colors are equal to active group colors of default-constructed QPalette
.
The following code can be used to create a color group with some colors specified:
The \l Palette type exposes color groups for each QML item state.
\qmlproperty color QtQuick::ColorGroup::accent
A color that typically contrasts or compliments \l base, \l window, and \l button colors. It usually represents the users' choice of desktop personalisation. Styling of interactive components is a typical use case. Unless explicitly set, it defaults to \l highlight.
\qmlproperty color QtQuick::ColorGroup::alternateBase
Used as the alternate background color in item views with alternating row colors.
\qmlproperty color QtQuick::ColorGroup::base
Used mostly as the background color for text editor controls and item views. It is usually white or another light color.
\qmlproperty color QtQuick::ColorGroup::brightText
A text color that is very different from windowText
, and contrasts well with e.g. dark
. Typically used for text that needs to be drawn where text
, windowText
or buttonText
would give poor contrast, such as on highlighted buttons.
\qmlproperty color QtQuick::ColorGroup::button
The general button background color. This background can be different from window
as some styles require a different background color for buttons.
\qmlproperty color QtQuick::ColorGroup::buttonText
A foreground color used with the palette
color.
\qmlproperty color QtQuick::ColorGroup::dark
A foreground color used with the palette
color.
\qmlproperty color QtQuick::ColorGroup::highlight
A color to indicate a selected item or the current item.
\qmlproperty color QtQuick::ColorGroup::highlightedText
A text color that contrasts with highlight
.
\qmlproperty color QtQuick::ColorGroup::light
Lighter than button
.
\qmlproperty color QtQuick::ColorGroup::link
A text color used for hyperlinks.
\qmlproperty color QtQuick::ColorGroup::linkVisited
A text color used for already visited hyperlinks.
\qmlproperty color QtQuick::ColorGroup::mid
Between palette.button
and dark
.
\qmlproperty color QtQuick::ColorGroup::midlight
Between button
and light
.
\qmlproperty color QtQuick::ColorGroup::shadow
A very dark color.
\qmlproperty color QtQuick::ColorGroup::text
The foreground color used with base
. This is usually the same as the windowText
, in which case it must provide good contrast with window
and base
.
\qmlproperty color QtQuick::ColorGroup::toolTipBase
Used as the background color for tooltips.
\qmlproperty color QtQuick::ColorGroup::toolTipText
Used as the foreground color for tooltips.
\qmlproperty color QtQuick::ColorGroup::window
A general background color.
\qmlproperty color QtQuick::ColorGroup::windowText
A general foreground color.
\qmlproperty color QtQuick::ColorGroup::placeholderText
Used as the place holder color for editable single line fields.
\qmlsignal QtQuick::ColorGroup::changed
Additional signal indicates that the current state of this color group has been changed. Usually it means that one of the colors is changed.
Construct object in default state.
