Can anyone provide a bit of enlightment about the XmNhelpCallback mentioned in a variety of places in Young and the OSF/Motif 1.1 docs It is described in Young (p.74) as being supported by all Motif widgets, and specifically as the only one called by the LabelWidget. Ok: I define ,declare and even provide a helpcallback for a given LabelWidget; Now the question is: When does it get called, and what does the user do to cause this?. It is never defined/clarified in the docs I have. E-mail is appreciated -- A summary shall be provided if needed. Thanks for your assistance: -dave "a geographer run amok on unix" bonnett- bonnett@seismo.css.gov

According to the Motif programmer's manual, most widgets do not bind a translation to the helpCallback. It is up to the application programmers to add their own translation for these widgets, typically to a HELP key press. Note that some Motif widgets, such as the file selection box, do have a help translation. -- Ken Lee DEC Western Software Laboratory, Palo Alto, Calif.

Note that some Motif widgets, such as the file |> selection box, do have a help translation. In Motif 1.1, almost all widgets have the translation: <Key>osfHelp: Help() Therefore, pressing the "osfHelp" key while the pointer is over the widget will invoke its Help callback, if available. Otherwise, it looks at its ancestors for a Help callback. On many systems, the "osfHelp" key is the F1 key. ----------------------------------------------------------------------- Mike Yang Silicon Graphics, Inc. mikey@sgi.com 415/335-1786
