Re: Notebook focus

["Ross McFarland" <rwmcfa1 neces com>]

i would venture a guess that you're probably getting the last widget b/c
you're using the same var when creating all of the pages and that's just the
last thing it pointed to.

you'd probably be better off passing the text widget in as a parameter to the
signal handler you set up for each of the buttons. that way each button gets
associated with the corresponding button i.e.

# create a page, add a text and button then
$this_pages_btn->signal_connect( 'clicked' => sub {
        shift; # get button off the stack, ignored
        my $text = shift;  # get the text widget off the stack
        $test->do_whatever # you should be dealing with the corresponding
                           # text for each button (per-page if you set it up
                           # that way)
    }, $this_pages_text );

you can re-use the this_pages_x stuff all you want and the handler should get
the corresponding text when a given button is clicked.

that should accomplish what you're wanting if i'm understanding your
description of the problem.
