GtkWidget* gimp_drawable_combo_box_new (GimpDrawableConstraintFunc constraint, gpointer data);
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.
| constraint: | a GimpDrawableConstraintFunc or NULL | 
| data: | a pointer that is passed to constraint | 
| Returns : | a new GimpIntComboBox. | 
Since GIMP 2.2
GtkWidget* gimp_channel_combo_box_new (GimpDrawableConstraintFunc constraint, gpointer data);
Creates a new GimpIntComboBox filled with all currently opened
channels. See gimp_drawable_combo_box() for more info.
| constraint: | a GimpDrawableConstraintFunc or NULL | 
| data: | a pointer that is passed to constraint |

layers. See gimp_drawable_combo_box() for more info.
