Is it possible to create multi-line labels through the resource file? XmStringCreateLtoR does the job correctly in the program, but I'd rather have the label set in the resourse file. If you could do me the favor of a personal reply, I would appreciate it. Thanks, Eric Slimko | Jet Propulsion Laboratories ems@socrates.jpl.nasa.gov | NASA/CalTech

Use the same name that Motif uses, and make sure the linker sees your converter before it sees the Motif converter, and you are golden. Do a name search on your motf library to figure out the name you should export. ------------------------------------------------------------------------- David Smyth david@jpl-devvax.jpl.nasa.gov Senior Software Engineer, seismo!cit-vax!jpl-devvax!david X and Object Guru.

Write a string to XmString converter which looks for \n. Use the same name that Motif uses, and make sure the linker sees your converter before it sees the Motif converter, and you are golden. Do a name search on your motf library to figure out the name you should export. Actually, you don't have to go to all that trouble. The following code replaces the String to XmString converter so you can use \n in resources. Just call MuInstallStringToXmStringConverter (yea, it's a long name, so sue me! :-) before you create your first Motif widget.
