tips to modify a Xt application running under openwindows

[Danielle Heinzer]

I need tips (either examples or indicators where to look in the manuals)
for modifying a Xt application which source I have. I did not write the
application but I would like to modify it.

o how to modify the window menu?

  I would like to have:
      Close
      Properties
      Back/Front
      Refresh

instead of the standard menu.

o how to open a popup window displaying a rasterfile when selecting properties
in the window menu

I am used to SunView. I have the Xt documentation, but cannot find the info.

Thanks,
