Description

This widget is somewhat similar to GtkColorButton, or more likely GimpColorButton.

It does not have its own color selection dialog however, it's just an ordinary button displaying a color. You have to connect some callback to its "clicked" signal. Also it uses GwyRGBA instead of GdkColor.

Functions

gwy_color_button_new ()

GtkWidget *
gwy_color_button_new (void);

Returns

a new color button.
