Description: Reference for Gtk.ColorChooser

### Interface

# GtkColorChooser

deprecated: 4.10

#### Description [src]

    interface Gtk.ColorChooser : GObject.Object

`GtkColorChooser` is an interface that is implemented by widgets for choosing colors.

Depending on the situation, colors may be allowed to have alpha (translucency).

In GTK, the main widgets that implement this interface are `GtkColorChooserWidget`, `GtkColorChooserDialog` and `GtkColorButton`.

Deprecated since: 4.10

Use `GtkColorDialog` and `GtkColorDialogButton` instead of widgets implementing `GtkColorChooser`.

#### Prerequisite

In order to implement ColorChooser, your type must inherit from`GObject`.

#### Implementations

- GtkColorButton
- GtkColorChooserDialog
- GtkColorChooserWidget
