The program you sent in works fine as is, although you should change lines
like:

  #include </usr/cluster/devel/sunview_devel/include/suntool/sunview.h>

to just:

  #include <suntool/sunview.h>

You must understand that SunView is an event-driven windowing system.
Once you call window_main_loop() everything that happens from then on must
be an 'event'.  By setting up event handler routines you can cause things
to happen when keys are pressed, the mouse is moved, the window is
resized, etc.  Once you get the hang of this you'll be pleasantly
surprised how powerful this concept is!
