ComboBox.getActiveId

Returns the ID of the active row of combo_box.

This value is taken from the active row and the column specified by the propertyGtk.ComboBox:id-column property of combo_box (see [gtk.combo_box.ComboBox.setIdColumn]).

The returned value is an interned string which means that you can compare the pointer by value to other interned strings and that you must not free it.

If the propertyGtk.ComboBox:id-column property of combo_box is not set, or if no row is active, or if the active row has a null ID value, then null is returned.
