    \brief A native color dialog.

    The ColorDialog type provides a QML API for native platform color dialogs.

    \image {qtlabsplatform-colordialog-gtk.png} {A native color dialog}

    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.

    \code
    MenuItem {
        text: "Color"
        onTriggered: colorDialog.open()
    }

    ColorDialog {
        id: colorDialog
        currentColor: document.color
    }

    MyDocument {
        id: document
        color: colorDialog.color
    }
    \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

    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.

    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").
