Including menubar prevents gtkdialog app from terminating via window manager

[GoogleCodeExporter]

I've taken the window widget's hide signal fix out of my test app and 
everything was fine until I started working on the menubar. Adding a menubar 
requires a menu and a menuitem so I don't currently know which widget is 
causing this problem but including them prevents gtkdialog from exiting when 
the app is closed via the window manager.

It's because the code in the destroy event is checking that all widgets have 
been destroyed before exiting but 1 remains when including a menu. My test app 
had 6 widgets without menubar+menu+menuitem but 10 with!

Right, I've got a handle on this now.

Each widget has an associated variable -- user defined or autogenerated -- that 
is stored in an array. When closing via the closewindow action function or the 
window manager, functions are executed that attempt to nullify variables 
attached to that particular window. The problem is the use of 
gtk_widget_get_toplevel() to match the variable being nullified to the window 
being closed: the menu widget is also a toplevel widget so what happens is that 
menuitem widgets don't get removed because their parent is the menu and not the 
window and they get left in the array causing these functions to assume that 
there's another window open.

There is a fix for this which I've been using because it was recommended and 
now I understand what's happening. <action signal="hide">exit:Exit</action> 
kills the application that refuses to close because the normal exit command 
quits the entire application so it's not checking that the variable array is 
empty.

I should be able to fix this with gtk_widget_get_ancestor(widget, 
GTK_TYPE_WINDOW).

What a nightmare!

Having used gtk_widget_get_parent() to dump a widget's family tree to the 
terminal I can see that the menuitems have two unknown ancestors and then nil. 
They can't be traced back to the window, so this is a problem. The GtkMenuItems 
are contained in a GtkMenuShell->GtkMenu which is attached to a GtkMenuItem on 
the GtkMenuBar, so it's the GtkMenuShell->GtkMenu that's causing the problem.
