The Athena label widget allows a bitmap (actually a pixmap) to be displayed
instead of text. One can then use Xlib calls to place graphics & text in
the pixmap. Two examples:
o xplot (plot(5) filter) - available from uunet.uu.net in
comp.sources.x/volume4/xplot/*
o xgnuplot (gnuplot X wrapper/terminal driver) - available from
uxc.cso.uiuc.edu in pub/xgunplot/xgnuplot.shar

Well, you can use any widget like a simple window. You just have to draw in its associated window obtained by XtWindow(). Personnally, I use the "simplest" widget, i.e. the Label Widget ... but don't forget your drawings will be erased by a mapping event ! To avoid this, use the XtNbitmap resource : for example, you can draw in both the window and the pixmap you associated to the widget, in order to see your drawings in "real time" and avoid mapping problems. ------------------------------------------------------------------------------- | ---- ___ | If Buddha had wanted Men to understand | | / /_ __ / _ __ __ ____ __ | Women, He wouldn't have give us aspirin | | / / / /_ /__/ / / /_/ / / / /_ | Confucius. | |-----------------------------------------------------------------------------| | vuichard@goofi.greco-prog.fr or vuichard@goofi.UUCP | | or ..!uunet!mcvax!inria!geocub!goofi!vuichard | -------------------------------------------------------------------------------
