### Class

# Gtk ColorChooserWidget

deprecated: 4.10

#### Description [src]

    final class Gtk.ColorChooserWidget : Gtk.Widget
      implements Gtk.Accessible, Gtk.Buildable, Gtk.ColorChooser, Gtk.ConstraintTarget {
      /* No available fields */
    }

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 `gtk_color_chooser_widget_new()`.

To change the initially selected color, use `gtk_color_chooser_set_rgba()`. To get the selected color use `gtk_color_chooser_get_rgba()`.

The `GtkColorChooserWidget` is used in the `GtkColorChooserDialog` 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 `GtkColorChooser::color-activated` signal for the given color.

# CSS names

`GtkColorChooserWidget` has a single CSS node with name colorchooser.
