Signals firing too often

[Daniel Kasak <dkasak nusconsulting com au>]

I've got a Gtk2::SimpleList that triggers some code when a row is selected.
The signal I'm currently using is 'button_release_event'. I've tried a 
fair few others.
The code that gets triggered updates the contents of the form, based on 
which row is selected.
The update process refreshes the data in the Gtk2::SimpleList, which 
seems to trigger more events, and it doesn't matter which signal I use, 
they all seem to get triggered multiple times. Without any further 
modification, I get 3 events.

So I've added a global variable, $do_company_update, which I set to 0 
right after the row is clicked, and before the rest of the code runs. If 
the 'refresh' code finds $do_company_update has a 1, it updates the 
SimpleList, otherwise if it finds a 0, it simply resets this to 1 and 
continues without refreshing the SimpleList. This reduces the number of 
my signals being fired from 3 to 2. I can't really see how the 2nd is 
being fired now.

The reason I began investigating it is that on the 3rd signal, the 
selected row would be reset to 0 ( which itself doesn't sound right, but 
that's another issue ). Now that I have only 2 signals, this behaviour 
has stopped and the form works as expected ( the code runs twice, but 
you only discover this inside a debugger - you can't tell from the form ).

What's going on?

Is there a signal I can use to catch when someone selects a row in a 
SimpleList that:
a) Won't get triggered if the SimpleList data is rebuild
b) Won't trigger multiple times?

Thanks!

Dan
