ComboA Gtk_Color_Combo is a widget that ease the selection of colors by the user. It is a special form of a Gtk_Combo_Box, that displays a special popup window, with a list of colors.
Note that nothing appears in the button, this your responsibility to update it when the user selects a new color (see the "changed" signal).
The recommended solution is to put a Gtk_Pixmap as the child of the button of the combo box ("Add (Get_Button (Combo), Pixmap)"), and updated it in the handler for this signal.
