1. GTK Issue

Irv,

I'm getting the following message when exiting texteditor.exu:

C:\gtk2\demos\textarea_file.e:147 in function ConfirmQuit()
A machine-level exception occurred during execution of this statement

^^^ call-back from Windows
Runtime error (Traceback unavailable)

Any idea?

Yes, that works!

Next issue: Closing the app when there is unsaved data causes this message:

(<unknown>:1376): GLib-GObject-WARNING **: invalid unclassed pointer in
cast to 'GtkWindow'

(<unknown>:1376): Gtk-CRITICAL **: file gtkwindow.c: line 1823
(gtk_window_set_transient_for): assertion 'parent == NULL || GTK_IS_WINDOW
(parent)' failed

HOWEVER, if I move the shell window out of the way, the "Quit Confirmation"
dialog shows up and I can click it and everything works fine. So, the only
issue is why does that message window pop up?

Maybe I'm misunderstanding the question.
Are you saying that the "Quit" dialog is popping up *behind* the 
shell window? 

When I run it from a DOS shell, the dialog shows up 
on top of everything else, and there are no messages or errors at the 
DOS shell prompt, either before or after I confirm or cancel.

When I run directly by clicking on the icon, no DOS window pops up,
and of course no error messages appear.

You are correct, those are diagnostics. GTK is saying that it's trying 
to dispose of some object that no longer exists, I think.
But they don't show up when I run the pgm. under Win98. 
What are you using?

No. I believe you. One thing I didn't try was closing the app from the 
button at top right of the window. That should be the same as closing 
it via the menu, but maybe it isn't. Which method did you use?

OK, I went back and tried closing using the button at upper-right. 
It still works ok, no errors. However, this got me to thinking:
if the file is 'dirty', then you should be prompted to save the 
file regardless of *how* you choose to end the program, including 
clicking on the close button. So, if you add one line to texteditor.exu 
as shown below, that should fix the problem, as all exits will be 
made thru the same routine.

----------------[ MAIN ]---------------
       
win = window(APP)
gtkSet(win,"Border",10)
when(win,"delete_event",confirm_quit,0) -- add me!

Eh? Maybe we're working with two different versions of the program, 
or with two different versions of EuGTK.

That might explain why I cannot reproduce the error.

There seems to be nothing left but the 2 different Windows versons. 
Maybe someone with XP could run the program and see what happens.
