How to simulate window close button (what I'm really trying to do...)

[Toralf Lund <toralf procaptura com>]

OK, maybe I should tell people what I'm really trying to do - see my 
other post.

Actually, I've been sort of wondering about how one might simulate 
button clicks or manu selections or whatever, but what I was really 
looking for this time was to run the window close-button behaviour, and 
I thought I might try doing it by emitting a fake delete event signal. 
I'm not really sure this is a good idea, but at least it seemed cleaner 
that sending an actual event to myself...

In any case, I'm on to something that has sort of bugged me for years; 
in all my Gtk/Gtkmm window I generally have a button called "Close" or 
"Cancel", or a "Close" menu item, depending on the context, that is 
supposed to do *exactly* what a window manager close or "window delete" 
will do. It seems to me that this isn't exactly uncommon, so why is 
there no way of telling Gtk(mm) exactly what I want? I mean, why can't I 
just say, "please let this button do a window delete", and forget about 
the rest? Or can I do this?

I know I can just connect the hide() method to my button, but that's not 
really the same thing, as the WM "delete" actually leads to a chain of 
events that may or may not end in hide(). In the particular case I was 
looking at, the application will in fact stop handling the delete before 
it gets that far if certain conditions are met.
