Hi monks,

I have a Tk app on Win32 with several buttons visible for users to press. One button has a binding configured for it like so:

$tl->bind("<Alt-Key-R>", sub { $Redo_PrettyPrint_b->invoke(); } );
[download]

Another button allows a user to invoke their own separate program with some parameters via putting their program's path in a variable that is then executed by a 'system' call. (The Tk app is self-contained and the user only wants it to run on his/her own behalf, and so I don't think I have concerns about tainting...)

-command => sub {
...
$ccmd_rc = system $auto_check_command, @ac_args;
warn "'Auto-Check' problem: ", $? >> 8, "\n" if $ccmd_rc;
...
[download]

My question is: What can the user do within the code of the $auto_check_command (which happens to be a Perl script :-) to invoke the aforementioned $Redo_PrettyPrint_b button? That is, how can their "other" Perl script "signal" the Tk app that has the $Redo_PrettyPrint_b button to react just as though the key sequence of 'Alt-Key-R' was pressed at the keyboard? The other script just needs to send this 'Alt-Key-R' sequence into the ether, it doesn't require feedback about success of its "virtual press" of the $Redo_PrettyPrint_b button. Thanks.
