[Pharo-users] Use of FileDialogWindow : getting the result

Hi ! I'm trying to fit a GUI in full screen mode, that uses a FileDialogWindow at some point. I'm able to recover the answer from FileDialogWindow when I it is opened modaly. However, since I would like to open it fullscreen with the selector #openFullScreen, the calling block does not wait and immediatly gets a nil answer. I was thinking of hacking my way out of it and subclassing FileDialogWindow to overide a method somewhere to call a block of my choosing but I really does not feel right. Has anyone a clue ? Thanks in advance for your time ! Thomas.
