gtk-tool-item-expand (item)

item -- a gtk-tool-item widget
expand -- a boolean whether item is allocated extra space

Accessor of the expand property of the tool item.

The gtk-tool-item-expand function returns whether item is allocated extra space. The (setf gtk-tool-item-expand) function sets whether item is allocated extra space when there is more room on the toolbar then needed for the tool items. The effect is that the tool item gets bigger when the toolbar gets bigger and smaller when the toolbar gets smaller.
