Refreshing GUI

[bcorr <bcorr micron com>]

I have a GUI that is used to drive the running of various tasks, some run locally by the GUI, others run remotely via LSF and I am wondering what the best method for keeping the GUI window contents refreshed would be.

 

The problem is that should the GUI be waiting on a job and is temporarily obscured by another window, when it is revealed again it sits there looking blank and obviously waiting for a refresh. I have tried something like this:

 

open (TMP, "$external_job_script 2>&1 |");
while (<TMP>) {
     Gtk->main_iteration while Gtk->events_pending;

}
close TMP;

 

but the problem is that the external jobs that use LSF just sit there waiting to run and so don't really kick the while (<TMP>) loop into life.

 

Can someone tell me what the best way of keeping the GUI window regularly refreshed would be?

 

Cheers,

 

Bill.
