* GtkColorChooserDialog:

|
|
* A dialog for choosing a color.
|
|

|
|
* 
|
|

|
|
* `GtkColorChooserDialog` implements the [iface@Gtk.ColorChooser] interface
|
|
* and does not provide much API of its own.
|
|
*
|
|
* To create a `GtkColorChooserDialog`, use [ctor@Gtk.ColorChooserDialog.new].
|
|
*
|
|
* To change the initially selected color, use
|
|
* [method@Gtk.ColorChooser.set_rgba]. To get the selected color use
|
|
* [method@Gtk.ColorChooser.get_rgba].
