| Allegro CL version 8.2 Unrevised from 8.1 to 8.2. 8.1 version |
Arguments: multi-picture-button
Returns (or sets with setf)
the value of the gap-size property of a multi-picture-button
control. This value is the extra pixel-width that is allotted for a
gap between certain buttons of a multi-picture-button. (A gap appears
wherever the keyword symbol :gap
is included within
the list of button-info
objects in the
multi-picture-button's range.)
The default value is 8. The value of the spacing property, which determines the general spacing between buttons, is added to the gap-size to find the total spacing between two buttons that have a gap between them.
A separator bar (a vertical line) is also drawn when the value of the
multi-picture-button
control's
button-3d-border
property is :when-pressed
. If a separator bar is
drawn in the gap, it is drawn in the middle of the gap area.
