I didn't analyze your source very careful, but I think I got what you
try to implement.
The easiest solution is to let ApplicationGuiManager handle your close requests.
The constructor of ImageWindow will connect a proper method of the
_Manager_ to the
proper signal.
If you need to do some processing inside ImageWindow, you could
implement something
like
  bool ImageWindow::mayICloseYou()
to ask about saving changes etc.
I think that changing your design will be easier than trying to make
gtkmm fit existing decisions.
