Creates a new GimpIntComboBox filled with all currently opened drawables. If a constraint function is specified, it is called for each drawable and only if the function returns TRUE, the drawable is added to the combobox.

You should use gimp_int_combo_box_connect() to initialize and connect the combo. Use gimp_int_combo_box_set_active() to get the active drawable ID and gimp_int_combo_box_get_active() to retrieve the ID of the selected drawable.

Creates a new GimpIntComboBox filled with all currently opened vectors objects. If a constraint function is specified, it is called for each vectors object and only if the function returns TRUE, the vectors object is added to the combobox.

You should use gimp_int_combo_box_connect() to initialize and connect the combo. Use gimp_int_combo_box_set_active() to set the active vectors ID and gimp_int_combo_box_get_active() to retrieve the ID of the selected vectors object.
