The "right" thing would be imho incorporating QGuardedPtr, so that any
pointer to that dialog is automatically invalidated. 

Well, I tried once something like

  QGuardedPtr<FancyDlg> pointer;

  pointer = new FancyDlg(parent, name);

  
the FancyDlg is modeless and gets somewhen closed. in the hideEvent() of
that Dlg I wrote "close(true)". This destructs it. 

However the QGuardedPtr didn't notice the destruction. So something must
gone wrong (anybody a clue?). 

However if we could get that somehow to work, it would be great.
