I have found that this does not work for me in the following case:
I have a rather complex widget hierarchy; but not extremely so,
I use a mainWindow that contains a Form passed as the work area of
the main_window. Then I have a ScrolledWindow child that contains a
another Form which is scrolled. It contains a group of RowColumns
each of which contain either labels or Text widgets. 

I want to set the keyboard focus to the first text widget created, 
so when use the XmProcessTraversal call exactly as specified in 
the FAQ and I get:
No focus on any of my widgets.  The focus did work correctly w/o
this call before I added the layers of the scrolled window and 2nd 
form. The resultant problem is that I grab the input on losingFocus
and if the widget never gets the focus well then it can't lose it....
Any solution would be appreciated greatly.
