I need a way to pause multithreaded Tkx application (threads are collecting some data via HTTP).
Threads push data to the queue so the main application can read it (and show to the user). Customer want to pause the program if one of the threads find some data. By pause i mean stop updating text log widget. Here is code:
sub start {
my @result;
$queue= Thread::Queue->new;
$queue_processed = Thread::Queue->new;
my @domains = get_domains($domains_filename);
$queue->enqueue(@domains);
my @threads= map { threads->create( sub { create_thread($_) } ) }
+( 1 .. $CONFIG{NUMBER_OF_THREADS} );
$_->detach for (@threads);
my $counter = 0;
while ( $counter < scalar @domains ) {
my $result = $queue_processed->dequeue_nb;
if ($result) {
$txt_processed_domains->configure(-state => "normal");
$txt_processed_domains->insert_end( "$result" );
$txt_processed_domains->see("end");
$txt_processed_domains->configure(-state => "disabled");
Tkx::update();
$counter++;
}
}
Tkx::tk___messageBox( -message => "Completed!" );
}
So i have one problem: how to pause all running threads (and continue them after some user actions)?

Are you posting in the right place? Check out Where do I post X? to know for sure.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
