[comp.windows.x] highlight objects in X11

Chi-Ming.Yang@CIVE.RI.CMU.EDU (07/24/88)

   I have displayed a tree structure (collection of boxs and lines segments)
in a window using X11R2.  Now I want to highlight one path from the root to
some leaf node.  One way to do this is to redraw the relevant lines and boxs
with thicker lines.   Another way is to 'highlight' the boxs as the command
button widgets in X11 Toolkit.   Could someone tell me how to do these?
Thanks.
