pygtk app does not exit via delete event on win32

I have a pygtk app running on windows and linux. The main GUI has close down function that is called from the delete event (when user clicks the X button on the window) or from the menu via FILE->QUIT

The code looks like this

def close_down(self):
    self.hide_gui()
    #do some cleanup stuff here, close down a log file etc...
    gtk.main_quit()

def on_close_down_activate(self, widget):  # From menu
    self.close_down()
    print("Closed")

def on_main_gui_delete_event(self, window, event): # From window X button
    self.close_down()
    print("Closed")

But when the user clicks the X button on the window, the word "Closed" is printed to the cmd line, but the app hangs and never returns control the the cmd line unless I kill python via the task manager. If the user selects Quit from the file menu the app prints the word "Closed" and returns control to the cmd line.

On Linux it acts as expected. Is gtk on windows keeping some thing going?

To close an application in PyGTK, you actually need two lines of code, not just one. My guess is that, in Linux, the window is closing, but the process is not. In Windows, nothing is closing.

To fix this, just add the following line below "gtk.main_quit()"

return False

The reason for this code is that, in pyGTK, you can leverage this line for creating "Are you sure you want to quit?" dialogs. If the line read "return True", the program would not close at all.
