Thanx for the info.
I think, then the solution to this problem will be, to code entirely in
Lingo Xtra using MUI and call it in
on runPropertyDialog.
And not coding GPDL at all.
In this case the entire GUI control will be in our hand.
Is this soltion right?

getPropertyDescriptionList?
As far as I know you can't. You can create your own dialogue for the user
to interact with in place of the standard GPDL, but there is no hook that
I'm aware of to validate user input at that point. The GPDL is simply
calling a special instance of the MUI Xtra or more rightly so, the GPDL is
called from within Director and the result (return value) is handed to the
MUI to display a dialogue. Once that process has been completed, the GPDL is
no longer activly involved. If you've used MUI, you now that you go through
the process of creating a list of widgets that will be drawn on the screen
as part of the dialogue box, when your done creating the initial list, you
assign it to the MUI instance and open the dialogue, the GPDL is really just
that list of widgets and their settings, nothing more. So the handler is
called on drop and it returns a widget list and then Director takes it from
there. I don't believe its possible to modify the results without reaching
in much deeper than the LINGO level to modify what is happening, because
you'd have to get deep into Director to locate the exit point of the entire
drag and drop configuration stuff.
I realize this doesn't help you much.
Sincerely
Mark
