I solved this problem a couple months ago when I wrote a "synchronous
GetString"
Xt.  (ie: a function that you call that pops up a dialog box, gets a string
from the user, and returns it to the caller w/o mucking around with callbacks,
etc.)

My solution is sorta kludgy but it "does the right thing."  I pop up the
dialog as an override-redirect window.  The dialog has a translation table
that maps "EnterWindow" events to an action procedure called Focus that
does an XSetInputFocus to the text widget inside the dialog.  Thus, when
the mouse enters the dialog I can type into it, and when it leaves the dialog
and enters another window, and ICCCM window manager reassigns keyboard
focus, thus undoing the effect of the XSetInputFocus by GetString.

Note that this will NOT work with a non-ICCCM wm that does not actively
set keyboard focus.. an application that uses this method must have an option
to not do the SetInputFocus.

I'll send a copy of the code, but your mileage may vary.
