A
gtk-separator-tool-item widget is a
gtk-tool-item widget that separates groups of other
gtk-tool-item widgets.
Depending on the theme, a separator tool item will often look like a vertical
line on horizontally docked toolbars.
If the
expand child property of the
gtk-toolbar widget is
true and the
draw property is
false, a separator tool item
will act as a "spring" that forces other items to the ends of the toolbar.
Use the
gtk-separator-tool-item-new function to create a new
gtk-separator-tool-item widget.
