A native color dialog.
\qmltype ColorDialog \inherits Dialog
! \instantiates QQuickLabsPlatformColorDialog \inqmlmodule Qt.labs.platform
The ColorDialog type provides a QML API for native platform color dialogs.
To show a color dialog, construct an instance of ColorDialog, set the desired properties, and call \l {Dialog::}{open()}. The \l currentColor property can be used to determine the currently selected color in the dialog. The \l color property is updated only after the final selection has been made by accepting the dialog.

\qmlmethod void Qt.labs.platform::Dialog::accept()
Closes the dialog and emits the \l accepted() signal.
Reimplemented from QQuickLabsPlatformDialog.

References QQuickLabsPlatformDialog::accept(), currentColor, and setColor().
QColor QQuickLabsPlatformColorDialog::color | ( | ) | const |
\qmlproperty color Qt.labs.platform::ColorDialog::color
This property holds the final accepted color.
Unlike the \l currentColor property, the color
property is not updated while the user is selecting colors in the dialog, but only after the final selection has been made. That is, when the user has clicked \uicontrol OK to accept a color. Alternatively, the \l {Dialog::}{accepted()} signal can be handled to get the final selection.

QColor QQuickLabsPlatformColorDialog::currentColor | ( | ) | const |
\qmlproperty color Qt.labs.platform::ColorDialog::currentColor
This property holds the currently selected color in the dialog.
Unlike the \l color property, the currentColor
property is updated while the user is selecting colors in the dialog, even before the final selection has been made.

QColorDialogOptions::ColorDialogOptions QQuickLabsPlatformColorDialog::options | ( | ) | const |
\qmlproperty flags Qt.labs.platform::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 Allow the user to select the alpha component of a color. \value ColorDialog.NoButtons Don't display \uicontrol OK and \uicontrol Cancel buttons (useful for "live dialogs").
