gtk:combo-box-active-id (object)

object -- a gtk:combo-box widget
active-id -- a string with the ID of the row to select, or nil

Accessor of the active-id slot of the gtk:combo-box class. The gtk:combo-box-active-id function returns the ID of the active row of the combo box. This value is taken from the active row and the column specified by the id-column property of the combo box. The (setf gtk:combo-box-active-id) function changes the active row of the combo box to the one that has an ID equal to active-id, or unsets the active row if active-id is nil. Rows having a nil ID string cannot be made active by this function.

If the id-column property of combo-box is unset or if no row has the given ID then the function does nothing and returns nil.
