I am working on a script whose logic is essentially as follows:
my $status = 0;
my $prev_status = 0;
my $mw = MainWindow->new();
my $status = check_for_status();
if ($status != $prev_status)
# need to notify user but don't wait for click
-title => 'status changed',
-message => 'status changed',
-type => 'OK',
-icon => 'info',
$prev_status = $status;
I would like the window to display and also have the program keep executing, but currently the program waits for the user to click "OK". The windows are only intended to notify the user that the status variable has changed and no action is taken based on clicking OK to close the windows. I was not able to find a Tk window type that does not have some sort of dialog button that causes execution to wait for the user to click them.
I also considered somehow using fork() to spawn off each dialog window as a separate process, but exec() expects a system call. Is there an equivalent to exec() that accepts a block of perl code that I can use to spawn off each dialog window and have execution continue within the main loop? Status changes are relatively infrequent so I don't expect the computer to be swamped with open dialog boxes.
