Webmaster Forum / Perl / Tk / August 2003

Guys,
If I create many pages in a notebook, and simplify it by doing this...
foreach (1..10) {
   my $page = $notebook -> add ("Page $_", -label => "Page $_") -> pack();

I need to disable a series of controls on some NoteBook pages.  To do so, I wrote a function like this:
=============
use Tk;
$mw = MainWindow->new;

How to parade the child widgets on a frame for a beautiful GUI?
Any help?
Thanks in advance

Is there a method that would allow me to create a labled button that
when pushed, would insert text into the text widget? I have tried using
insert in the following way:
$f->Button(-text => "insert", -command => \$insert 'end', "Dmin")->

I have some buttons and Labels packed on the mainwindow. But when i click on
another option from the menu i want to clear them all (and the memory if it is
possible) and create new ones.
Is this posssible?

I give up!  This script shows a hit time for allocating the array and a very
snappy launch of the sleeps by both the parent and the child.  The parent is
blocked waiting on the system call to finish.

I think you're confirming what I had poorly tried to say.  exec is *only*
useful, if I am first willing to fork the parent (30MB ram copy) and the use
the parent to run the TK app and the child to exec my small process (which
gets rid of the 30MB ram of the child).  But the 30MB hit ...

I just did the script below as a test.  Yes, it allocates up some RAM, execs
the sleep and the original process goes away and the sleep is the only thing
left.  But, it only helps a little because I need the original process to
stay alive, so I would need to fork and have the child ...

Tim,
If your fork and then execute using exec " some program", doesn't the new
program called by
exec replace the original in memory. At least this is what I understand to be

Is there an example you can point me too, of a socket method that works in
both Unix and Win32?  Or perhaps something similar to the Win32::ProcFarm
that Toby suggested but that will work on both?
Thanks.

Any idea?
