Emmit Custom Signals

["JOSE PEDRO SERGIO ROMAO MACHADO" <a15993 alunos det ua pt>]

Hi all,
I need you opinion on this problem:

I have a Timer function in the main.c of my app, that 
reads some dada from a text file at each second.
I must update some widgets with this data, text boxes, 
progress bars, plot graphs, etc...

As I see I have two solutions:

1) leave timer on main.c, use global variables and emmit 
acustom signal to those widgets tha must be updated... so 
they can go read global variables to update them selves.

2) I can move the timer to the function that creates one 
of this widgets so it can auto-update that widget.

This last solution has a problem, I can only update ONE 
widget...

Any advices?!


Thanks in advance!!!
