in thread Using Tk::ProgressBar

Threads and Tk,are NOT wrong, but they have to be done with alot of care. You cannot mix Tk code across threads, and all threads must be created before any Tk code is invoked in the main thread. See Tk-with-worker-threads or this simple example:
#!/usr/bin/perl use strict; use threads qw[ async ]; use threads::shared; our $WORKMAX ||= 1_000; #by BrowserUk ## A shared var to communicate progess between work thread and TK my $progress : shared = 0; sub work { for my $item ( 0 .. $WORKMAX ) { { lock $progress; $progress = ( $item / $WORKMAX ) * 100; } select undef, undef, undef, 0.001; ## do stuff that takes t +ime } } threads->new( \&work )->detach; ## For lowest memory consumption require (not use) ## Tk::* after you've started the work thread. require Tk::ProgressBar; my $mw = MainWindow->new; my $pb = $mw->ProgressBar()->pack(); my $repeat; $repeat = $mw->repeat( 100 => sub { print $progress; $repeat->cancel if $progress == 100; $pb->value($progress); } ); $mw->MainLoop;
