I'm coding an application that requires a status bar. After some problems, I was able to get that working, however I again run into a new problem (suprise suprise! lol). I have the status bar in a new Tk window for convienence sake, however while the status bar is doing it's update, and the window is shut down, I get a nice error. ie:

#some code here
$status_bar->update;
#more code here

#user action: shut down $status_bar

error:
Tk::Error Usage $widget->update(...)
And so forth

Point being, how do I test to see if $status_bar actually exists before the update code is run? This way, I could at least counter it in some way, without having to deal with nasty error messages?
