DESCRIPTION
XmeClearBorder clears the border highlight and/or shadows
bordering a rectangular widget. To clear these window
decorations, XmeClearBorder paints them in the widget's
background color.
The border highlight surrounds the perimeter of a widget.
When calling XmeClearBorder to clear the border highlight,
your widget should do the following:
o Set x and y to 0.
o Set width and height to the width and height of
window.
o Set thickness to the highlight thickness. (If you are
subclassing a primitive widget, then the highlight
thickness is stored in the field
primitive.highlight_thickness.)
The widget's shadows lie within the border highlights. When
calling XmeClearBorder to clear the shadows, your widget
should do the following:
o Set x and y to the highlight thickness.
o Set width so that it equals the width of the window
minus twice the highlight thickness.
o Set height so that it equals the height of the window
minus twice the highlight thickness.
o Set thickness to the shadow thickness of the widget.
(If you are subclassing a primitive widget, the shadow
