class: ColorChooserWidget

[27:7] extends: object

The GtkColorChooserWidget 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 create a GtkColorChooserWidget, use [ctor@Gtk.ColorChooserWidget.new]. To change the initially selected color, use [method@Gtk.ColorChooser.set_rgba]. To get the selected color use [method@Gtk.ColorChooser.get_rgba]. The GtkColorChooserWidget is used in the [class@Gtk.ColorChooserDialog] to provide a dialog for selecting colors.

Actions GtkColorChooserWidget defines a set of built-in actions: -

color.customize activates the color editor for the given color. - color.select emits the [signal@Gtk.ColorChooser::color-activated] signal for the given color. # CSS names GtkColorChooserWidget has a single CSS node with name colorchooser.
