Functions:

• new () -> Gtk.Widget

Description:

The Gtk.ColorChooserWidget widget lets the user select a color. By default, the chooser presents a predefined palette of colors, plus a small number of settable custom colors.

It is also possible to select a different color with the single-color editor. To enter the single-color editing mode, use the context menu of any color of the palette, or use the '+' button to add a new custom color.

The chooser automatically remembers the last selection, as well as custom colors.

To change the initially selected color, use Gtk.ColorChooser::set_rgba().

To get the selected color use Gtk.ColorChooser::get_rgba().

The GtkColorChooserWidget is used in the Gtk.ColorChooserDialog to provide a dialog for selecting colors.
