| Allegro CL version 8.2 Unrevised from 8.1 to 8.2. 8.1 version |
Arguments: standard-object
Returns the value of the click-off property for its argument. This property determines whether a button can be un-pressed by clicking it when it looks pressed in.
This property applies to button controls that remain depressed after
clicking them. Sometimes it is desirable to allow your users to
un-press the button by clicking a second time, while other times it is
desirable to require some other action such as clicking another button
in the same cluster or within the same multi-picture-button
.
Here are the possible values and their effects:
nil
: users can only deselect the button by
clicking on another button in the same cluster (or by setting the
value programmatically).
t
: users can deselect the button by clicking
on it again once it has been selected, i.e., the control will toggle
on and off.
click-off is a
property of the multi-picture-button
, picture-button
, and
radio-button
classes.
This property will have no effect on GTK for radio-button
s, since you can never turn a
radio-button
off by
clicking it.
