Tk::Text, is there a selection?

Hi,

from the documentation to Tk::Text i concluded that i can get
the selection by:

$txt->get('sel.first', 'sel.last');

But i need to test if there IS a selection.  To do this i
should test if the option "exportSelection" is true.

How do i do that?  I tried:

$t->cget('exportSelection')

But that was always true.  How do i test for the selection?


Best regards,
Torsten.

Or via $txt->getSelected;

What's wrong with:

print "Nothing selected\n" unless $t->getSelected;

I do not find any reference to "getSelected" in Tk::Text,
even now that i know it exists.  Else i think i would have
used it.


Thanks,
Torsten.

I'm running perl/Tk 804.027 and the getSelected method is documented,
so perhaps the pod has been improved.

Yes. I did that for 804; with the permission of O'Reilly publishing and
Steve of course ;)

As wonderful as Mastering Perl/Tk is - I got tired of having to always look
them up. Surprisingly, the book binding has held up rather well around p.189
