typable

Arguments: combo-box

Returns the value of the typable property of the argument. This property of combo-boxes determines whether users must select values from the drop-down list (value nil) or whether they may type in a new value directly (value t). typable is a property of the combo-box and the combo-box-column-mixin classes.

For combo-box controls, the typable property may not be changed on an existing control, and must instead be specified with the inspector when designing a control (using a form) or with the :typable initarg of make-instance. It can be changed using the inspector when designing a form but not for a running control, either in the IDE or in an application. This restriction does not apply to combo-box-column-mixin columns of grid-widgets.
