[Gtk-sharp-list] (best practices) how to retrieve the output from the dialog

  This is in some way continuation of my old post about showing modal 
dialog "How to show dialog modal and wait for it?".

  I still have problems to come up with elegant way to show and 
respond to the output of the dialog.

  Example: main window + custom filter dialog (modal). If user press 
OK in dialog the data in main window should be filtered, if user 
cancels dialog, nothing should happen.

  Normally I would write something like this:

  if (dlg.Filter!=null)
    // do filtering

  In Gtk# world this is incorrect, because the if clause is executed 
before dlg closes.

  I figured out that I can write additional functions -- even 
handlers -- one per each dialog I use, but this is ugly for me 
(having N dialogs results in N triggers, one liners usually, and N 
output handlers).

  So, what is the best (elegant!) practice for this in Gtk#?
