Ok, after finally getting 5.8.x(had to wait until I had the money for
PDK 5.x), I tried this. I used the following:
use win32::GUI;
use threads;
use Thread::Queue;
# contruct GUI here -->
my $Window = new Win32::GUI::Window (
-name => "Window",
-topmost => 1,
-left => 300,
-dialogui => 1,
-top => 400,
-width => 222,
-addstyle => WS_VSCROLL,
-height => 300,
-text => "Test",
#-class => $class,
);
$Window->AddButton(
-name =>"SomeButton",
-top => '30',
-left => '1',
-text => "TipTest",
-tip => "This is a Tip!",
-width => 150,
-height => 25,
);
$Window->Show();
$Window->Enable();
$Window->Center();
my $commandQueue = Thread::Queue->new;
threads->new(sub {
while (my $command = $commandQueue->dequeue) {
eval $command; warn $@ if $@;
}
});
Win32::GUI::Dialog;
sub function
{
my $var = shift;
sleep 5;
print $var,"\n";
print "Pending Threads: ", $commandQueue->pending,"\n";
}
sub Window_Terminate
{
for(1.. $commandQueue->pending)
{
$commandQueue->dequeue_nb();
}
undef $commandQueue;
return -1;
}
sub SomeButton_Click {
$command
This works, but the problem is when I exit the program, I get this
"warning" printed to STDOUT:
d:\>gui100.pl
A thread exited while 2 threads were running.
Anyone know how stop this? Also, now that I have 5.8, I hope to be able
to use threads more often. Can anyone give any "gotchas" they have
found?
