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.
