The 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 set_rgba. To get the selected color use get_rgba.
The ColorChooserWidget is used in the ColorChooserDialog to provide a dialog for selecting colors.
GtkColorChooserWidget has a single CSS node with name colorchooser.
