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.In reply to how to use eventGenerate in Tk by tobbes
