RE: [perl-win32-gui-users] Doevent problem in minimised window - Please help

[Peter E. <Pet...@at...>]

Note sure why it stops when minimized, I assume it is a scope issue and is
supposed to happen. Nevertheless, change your for() loop to a _Timer event
and it [1] should work, [2] be more Windows-y, and [3] allow you to do other
things with the window in between counts (whereas sleep will only sleep).
Then, don't forget to add a Win32::GUI::Dialog() line, as well as a
Main_Terminate sub to handle that event.

Please help


I am new to Win32::GUI . I have written a basic program (copied from
examples) 
as below

use Win32::GUI;
$main = Win32::GUI::Window->new(
  -name    => "Main",
  -title   => "Win32-GUI: Doevents-Demo",
  -left    => 100,
  -top     => 100,
  -width   => 600,
  -height  => 400,
);
sub Main_Terminate() {
  print "Main window terminated\n";
  return -1;
}
$textfield = $main->AddTextfield(
  -name   => "Textfield",
  -text   => "have fun and more",
  -left   => 75,
  -top    => 150,
  -width  => 200,
  -height => 40,
  -readonly => 1,
);

$main->Show();
 
$textfield->Text("Processing infile...");

for ($linenr=0;$linenr<2000;$linenr++) {
  print "$linenr\n";
  $textfield->Text("Processing line $linenr");
  $main->DoEvents();
  sleep 1; #body of the loop...
}

The problem is that when I minimise window , the counting in the for loop
stops !
That is value of $linenr does not increment ! After checking I found out
that program
stops at Doevents function when window is minimised ! The moment I restore
the minimised
window, the counting proceeds !

Can somebody tell me what am I doing wrong ??

Operating system W2K Service pack 3
perl v5.6.1
Win32::GUI - 0.0.665
