In Motif 1.0, I am creating a form and then creating children of the form. Is there a way to later find out what the form's children are, besides keeping track of them as created? Thanx in advance for any help, Max B. -- Max Behner | "I used to be disgusted - now I Inter: behner@austin.lockheed.com | try to be amused!"

But i would like a way to get access to any widget's children. My problem is that i have a bulletin board dialog that contains two edit fields, three pushbuttons and some lables. When the user presses the OK-button a callback function is called. Then I would like to have access to the text in the edit fields, but those widgets are defined in a different function. Do I have to define all widgets globally, or is there a simpler and cleaner way. I know about sending arguments to the callback routine, but what about the second (and third and.... widget). Help on this matter would be highly apprechiated (where is my diksjonary??? :-) KMLUND. (This would not be a problem on an Amiga...) (Perhaps it's no problem here either??)

But try: WidgetList ch; Cardinal ch_count; XtVaGetValues(form, XmNchildren, &ch, XmNchildCount, &ch_count, NULL); Note that `ch' is read-only. Ik Su Yoo RRC 1H-229, (908) 699-5764 ik@ctt.bellcore.com

Oops, the resources should have been XmNchildren and XmNnumChildren. Also, both `ch' and `ch_count' are read-only. Sorry for the confusion. (BTW, these are documented under Composite(3X).)

Also be forwarned that some of the children of manager widgets are not "real" objects. If you are going to be doing things to the children returned, check XtIsObject(ch[n]) before doing anything to it. If it isn't an object, then don't use it. --Bill Turner (bturner@hp-pcd.cv.hp.com) HP Interface Technology Operation
