I am trying to use Perl's Tk module for guis. From what I understand it should be possible to generate events programatically which will then will trigger any listeners on a widget. So i did the following:

use Tk; my $mw = new MainWindow; my $label = $mw -> Label(-text=>"Hello World") -> pack(); my $button = $mw -> Button(-text => "Quit"); $button->bind('<ButtonPress-1>' => \&myexit); $button->pack; MainLoop; $button->eventGenerate('<ButtonPress-1>'); sub myexit { exit; }

Here I create a window with a label and a button and whenever the button is clicked the program should exit. It works perfectly when actually clicking the button. When trying to generate a click, nothing happens. I have also read about virtual events, are these a special kind of events, so that I can generate only events of that type? What I wonder is whether I am unable to generate builtin events like keypress and such. Any help would be very welcome.

Hmm, I just realized that maybe MainLoop is halting the entire program, thus eventGenerate is never reached. But in that case eventGenerate seems rather pointless.
