\since 6.4
\brief A color dialog.
The ColorDialog type provides a QML API for color dialogs.
\image qtquickdialogs-colordialog-gtk.png
To show a color dialog, construct an instance of ColorDialog, set the
desired properties, and call \l {Dialog::}{open()}. The \l selectedColor
property can be used to determine the initially selected color in the
dialog.
\code
MenuItem {
text: qsTr("Color")
onTriggered: colorDialog.open()
}
ColorDialog {
id: colorDialog
selectedColor: document.color
onAccepted: document.color = selectedColor
}
MyDocument {
id: document
}
\endcode
\section2 Availability
A native platform color dialog is currently available on the following platforms:
\list
\li iOS
\li Linux (when running with the GTK+ platform theme)
\li macOS
\endlist
\include includes/fallback.qdocinc

/*!
\qmlproperty color QtQuick.Dialogs::ColorDialog::selectedColor
This property holds the currently selected color in the dialog.
The \l {Dialog::}{accepted()} signal can be handled to get the final selection.
When the user has clicked \uicontrol Open to accept a color, a signal handler
for the \l {Dialog::}{accepted()} signal can query the selectedColor property to
get the final color that was selected by the user.
\sa {Dialog::}{accepted()}

/*!
\qmlproperty flags QtQuick.Dialogs::ColorDialog::options
This property holds the various options that affect the look and feel of the dialog.
By default, all options are disabled.
Options should be set before showing the dialog. Setting them while the dialog is
visible is not guaranteed to have an immediate effect on the dialog (depending on
the option and on the platform).
Available options:
\value ColorDialog.ShowAlphaChannel Show a slider and additional input fields for the alpha value.
\value ColorDialog.NoButtons Don't display \uicontrol Open and \uicontrol Cancel buttons (useful
for "live dialogs").
\value ColorDialog.NoEyeDropperButton Don't display \uicontrol {Eye Dropper} button. This value was added in Qt 6.6.
\value ColorDialog.DontUseNativeDialog Forces the dialog to use a non-native quick implementation.
