gtk:combo-box-button-sensitivity (object)

object -- a gtk:combo-box widget
sensitivity -- a value of the gtk:sensitivity-type enumeration

The accessor for the button-sensitivity slot gets or sets whether the combo box sets the dropdown button sensitive or not when there are no items in the model.

The :on value if the dropdown button is sensitive when the model is empty, the :off value if the button is always insensitive or the :auto value if it is only sensitive as long as the model has one item to be selected. The gtk:combo-box implementation is deprecated since 4.10. Use the gtk:drop-down widget instead.
