Re: Accessibility of Gnome panel / How to end session via keyboard

["John Zitterkopf" <zitt zittware com>]

I've been meaning to send this mail for a couple of weeks... As usual I got
involved in a couple of other projects and wasn't able to follow up with
this email until now (when I should be in bed. <grin>)

After sending out the email saying it didn't work; I approached the problem
again the next day after a nights sleep and some relaxation.

The patch worked! What I think happen is either I forgot to copy the new
binary over when I was trying to figure out what was wrong... or there
were/are TWO places in the code that needed to be changed. I may have made
the change in one place and not the other.

I'm now able to initiate a logout via keyboard using Padraig's patch
information. THANKS PADRAIG! <grin>

I'm trying to understand a few things in the code; maybe someone can shed
some light:

1) Can someone point me to a good set of documentation on:
a) Applying Patches to source trees.
b) What are .spec files and how do I use them?
c) docs on how to use CSV?

2) I've kind of been hacking around in the gnome panel source code trying to
figure out how the events / functions are fired (in what order). I've put
some debug messages when go out to a file in various places in the code; but
haven't figured out the order or enough information to make heads or tails
on how the events occur.

Basically, what I'm trying to do is:
1) Perform (application specific in my case) certain actions when the
gnome-panel has been constructed and is loaded and ready for keyboard input.
2) Perform a certain action when the menu is brought up on screen. IE if the
user hit ALT-F1 I wanted to do something after the menu is displayed.
3) Perform an action when the menu is dismissed / hidden.
4) Perform an action when the menu is destroyed ... ie when the gnome
session has ended.

In my application specific case; I wanted to send strings to a file which
are read at various intervals to determine how execution is progressing.
Kind of like an automated testing environment. I have another app which
wakes up and reads this file to see where the execution has occurred and
will flag errors for examination later.

I have some of these working by placing messages in various events like:
INIT_MENU and Create_menu_at_fr() ... as I recall; but I was hoping to get a
little more detail and/or a more robust method.

Any ideas / brainstorms?
John
