"color-set" void user_function (GnomeColorPicker *colorpicker, guint arg1, guint arg2, guint arg3, guint arg4, gpointer user_data);
GtkWidget* gnome_color_picker_new (void);
Creates a new GNOME color picker widget. This returns a widget in the form of a small button containing a swatch representing the current selected color. When the button is clicked, a color-selection dialog will open, allowing the user to select a color. The swatch will be updated to reflect the new color when the user finishes.
Returns : | Pointer to new GNOME color picker widget. |
