Both yours and someone else's answer was mostly what I was looking for. In
the long run I am trying to create a window with many (at most 10) lines of
words. Each line will contain different text and have a number in
it. Ideally I would like the lines to be of different colors. A sub will
run collecting the number to plug in to the lines.
At the time I wrote the email I did not see the doevents() which I am
looking at now. And no I am just learning this widows programming.
Are there any good references on line where I can learn more about this
type of programing in perl? Are there more examples any where?
Thanks,
Louis

I don't quite see where your problem is ... do you want to know HOW to
update your window or WHEN?
As for the how, your $sb->Text("whatever"); should work fine anytime. As for
the when, maybe you are looking for a timer so that you can update the
status bar every other second or so.
No offence, but maybe you just need to grasp the messaging concept of
windows? I mean, when does which part of the script run and pass control
where? That can admittedly be confusing. Forgive me, if that was not what
you wanted to know:
Your Win32::GUI::Dialog(); call (btw: where IS your Dialog() call??) passes
control to the GUI, which loops for events and calls the event handlers
(e.g. your Button_Click sub) until ANY of these subs returns a negative
number (not just Main_Terminate). A lot of those event handlers do some
default stuff, like redraw all the controls of your window when it becomes
visible. If you have an event handler that runs forever (maybe in a loop of
your own that processes a giant file line by line), then the $sb->Text("20%
done"); call does alter the status bars text property, but the redraw
message, which writes the new text onto the window for you to see never gets
called, because your program is inside this long running sub and not passing
control back to the GUI Dialog loop. In that case, simply call
Win32::GUI::DoEvents(); inside your script and the outstanding events will
be acted upon.
Again, sorry if this is not what you asked for.
Have fun,
Harald
