Hi experts, I am not a full programmer. I kind of do it for my needs. My request could be easy to do with Perl-Tk but I have no clue how to...

I have a notebook with Sheets added inside a foreach loop. Inside each tab I have Text area that displays log using fileevent. Works really well.

The window is launched and $log_display->insert('end', $_ ); works great.

I want to 'add' more tabs to this notebook dynamically from another job start if a condition is met.

Since the widgets are created already, I was looking for a function like 'get all opened mainwindow' and for the new job, I thought I could add the new tab to the handle.

My code skeleton looks like:

my $window = Tk::MainWindow->new();
my $book = $window->NoteBook();

#geometry, pack, title etc

@input=("corner1","corner2")#generated by another loop

#other buttons frames etc

foreach my $corner (@input) {
$tab = $book->add("TAB $index", -label => "$corner");
$for_display=$tab->Scrolled('Text', )->pack();
#blah blah
$CHILD = IO::Handle->new;
open($CHILD, "$unix_command 2>&1 |");
$logWindow->fileevent($CHILD, 'readable', [\&callback,args]);
}

#then using sub callback will insert the $_ if sysread.

I want to update this mainwindow when I start the same pm file. My application request is not allowing me to 'add' using a button or so. I have to detect the previous window and add to it. hope I was clear! :-)

how to achieve this?
