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.
