Can anybody tell me how to use the Xmu function "XmuCvtStringToWidget". I
want to specify a widget name in a resource file so that I can connect
two widgets together on an XmForm. ie.

MyProggy*MyListSW.topWidget:               MainTextSW

However, when I run the program, I get the message:

Warning: No type converter registered for 'String' to 'Window' conversion.

(Just like the manual sez).

I have managed to find this bit of code which seems to be the correct way
to go about this:

    static XtConvertArgRec parentCvtArgs[] = {
        {
            XtWidgetBaseOffset,
            (XtPointer)XtOffsetOf( CoreRec, core.parent ),
            sizeof(CoreWidget)
        }
    };

    XtSetTypeConverter( XtRString, XtRWidget, XmuCvtStringToWidget,
                            parentCvtArgs, XtNumber(parentCvtArgs), XtCacheAll,                                NULL );


However, I haven't got a clue where to put it! The example code I have seems
to suggest I can only do this if I am creating my own widget; but elsewhere it
says that I can add it to a widget's "class_intialize" function. HOW? What's
one of those? :-(

If anybody has any code to do this, please let me know the trick - I'm sure
this is a FAQ.

Thanks in advance,

Rik.

PS: What are the header files "CoreP.h" and "IntrinsicsP.h" - should I use
    these or "Core.h" and "Intrinsics.h" (OK I know RTFM:-)
