simple-click-toggle

Arguments: multi-item-list-or-outline

Returns whether multi-item-list or outline control requires the user to hold down the control key while clicking an item in order to toggle the selected state of that single item. If nil, a simple left click will deselect all other items (which is typical Windows behavior); if true, a simple left click will toggle the clicked item only. Note that holding down the shift key while clicking to select a whole range of values (also typical Windows behavior) is possible only when this property is nil. The default value is nil for multi-item-list and t for outline.

For a multi-item-list, this property must be specified with the :simple-click-toggle initarg to make-instance when creating the multi-item-list instance; it cannot be changed later. For an outline, this property is used only when the multiple-selections property is true.

simple-click-toggle is a property of the multi-item-list and outline classes.

GTK note: It's not feasible to implement this option for the multi-item-list widget on GTK. The widget will always behave as if simple-click-toggle were nil.
