Hi Monks,

I'd like to run another program from my script. Both programs have a Tk interface. My problem is that when child exits, the MainWindow of the main script loses focus. It is a problem for me because the main program uses a barcode reader in keyboard emulation mode. When the MainWindow loses its focus, the bindings of the keyboard to $mw don't work, of course. I don't want to tell the operators to left-click into $mw before using the barcode reader.

Is there a way to give the focus back to $mw after the child process closes? Here is my code, it doesn't give back te focus:

$mw->iconify;
$mw->withdraw;

unless(open(HND,"<vmapper.ini"))
 {
  &fileRdWrError('vmapper.ini','read','p1_appendMsgToLog');
  exit 0;
 }
my $line = <HND>; chomp $line;
close HND;
system($line.'vmapper.exe');
#other program exited, continue from here
$mw->raise;
$mw->deiconify;
$mw->update;
$mw->focus; #should give the focus back here

Thanks,
