Re: how to use eventGenerate in Tk

[zentara]

Hi, first off, you have a glaring error in your program flow. Once the line MainLoop is encountered, no further lines are processed until the MainLoop ( the Tk event loop system) is destroyed. So you never call eventGenerate until the Tk eventloop is gone, so it probably tries to run but throws an error.

#!/usr/bin/perl
use warnings;
use strict;
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;

$button->eventGenerate('<ButtonPress-1>');

$mw->repeat(1000 => \&doit);

sub doit {
     $button->focus;
     $button->eventGenerate('<ButtonPress-1>');
}

MainLoop;

sub myexit
{
  print time."\n";
  #exit;
}
