## Detailed Description

This interface can be implemented by widgets which allow the user to choose a color.

Depending on the situation, colors may be allowed to have alpha (translucency). The main widgets that implement this interface are ColorChooserWidget, ColorChooserDialog and ColorChooserButton.

Since gtkmm 3.4:

This is a default handler for the signal signal_color_activated().

Glib::PropertyProxy< Gdk::RGBA > Gtk::ColorChooser::property_rgba | ( |  | ) |

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:
  A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

Glib::PropertyProxy_ReadOnly< Gdk::RGBA > Gtk::ColorChooser::property_rgba | ( |  | ) | const

Current color, as a GdkRGBA.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:
  A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

Glib::PropertyProxy< bool > Gtk::ColorChooser::property_use_alpha | ( |  | ) |

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:
  A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

Glib::PropertyProxy_ReadOnly< bool > Gtk::ColorChooser::property_use_alpha | ( |  | ) | const

Whether alpha should be shown.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:
  A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

## Friends And Related Function Documentation

Glib::RefPtr< Gtk::ColorChooser > wrap | ( | GtkColorChooser * | object,
|  | bool | take_copy = `false`
| ) |  | `[related]`

A Glib::wrap() method for this object.

Parameters:

  object | The C instance.
  take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns:
  A C++ instance that wraps this C instance.
