[Gambas-user] behaviour of Last + Timer events

[richard terry]

I got caught recently with a bug - many many weeks to uncover it, until I did 
by random chance - a mix-up of what actually was 'Last'. So my question 
basically is how Gambas determines what is 'Last'.

I often use 'Last' in subroutines where I may have several controls which are 
the same, and I have a common group eg say combo1,2,3, , where the group name 
is say my_combos where each control has a tag, here lets 
say "one", "two", "three"

The code could be

public sub my_combos_click()

Select case last.tag
     case "one"
		do somthing
    case "two"
               do something
    case "three"
              do something
end select	

As a result of whatever code I have in 'do something' I may then again 
reference Last:

something else = Last.text

end 


Now, what was happening in my program that on the main form - not the form 
that I had the bug on -  I had a timer, which was firing every 10 minutes. 
when my program crashed unexpectedly at one point, I inspected the properties 
and found that the 'Last' referenced had ceased to be the 'Last' in my 
subroutine, but had become the 'Last' control that fired an event - suddenly 
the Timer on another form.

As it turned out when I checked my code - it was my fault anyway - faulty 
code, but it made me want to ask the question about how Gambas defines what 
is Last. Seems to be a system-wide property - not just the last thing on a 
particular form.

Any observations/comments.
