modal GtkFileSelection

[Derethor <derethor thepentagon com>]

 hi guys!

 Is There any way to get a GtkFileSelection working in modal mode?

 I'd like to have something like

 file = ask_file ("choose your file");

 I tryed  with gtk_window_set_modal, but it seems that it is not working
(I mean, the program continues the execution)

 Looking in the API desing, I believe than I have to write a callback
connected to the okey button, and do all my stuff there... but, I need
something general...

 For sure, I'm missing something... right?

 thanks!
