Thanks, Lyle... I'll cc Jeroen and on this then.

I'll leave it on fxruby-users in case someone else
can learn from it.

Jeroen:

I'm trying to understand this sentence:

     "setFocus() puts a widget into the focus chain. If the toplevel
      widget had the REAL focus from the window system [the window
      manager only assigns keyboard focus to a toplevel window], then
      setFocus() generates a SEL_FOCUSIN message; note that in the
      process of child->setFocus(), the whole chain is built up by upward
      recursion, and the child does not become switched into the focus
      chain until the parent is also."

Does this mean I can't do a setFocus on a modal dialog box or its
contents? What is meant by a toplevel window -- one that stands alone,
or an actual main window?

All I'm trying to do is display a modal dialog box and give the focus
to the single text field in it. Nothing I try works.

Surely this is doable??

Thanks much,
Hal Fulton
