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
.
