What is wrong with this:
$exCB = $MW -> Checkbutton(-text=>"exclusion",
            -variable=>$eX,
            -command=>sub{print "\n$eX\n";},

I have a Toplevel containing a text widget. I'd like to prompt the
user to save the contents if he clicks the window's close button.
OnDestroy seems to be way to do this, but I need to pass arguments to
the ondestroy method; the syntax for this is not clear. When I use the

I'm trying to make a simple application that displays an image.
However, 'pack' insists I give it an option, but I've no clue
what option it wants. Neither the Tk::Photo manual page, nor

I'm new to Perl::Tk, and I'm trying to add an image to my window. I've

                           $mw_wizui->Unbusy(-recurse => 1);}

I was intreseted to see anyne can provide me with an answer/opinion.
Also, does any one know of a Wx newsgroup.

Does any one know if there are buffering issues specific to Tk?  Eg., a
filehandle other than STDOUT to which inserts, etc. are sent?
I recently learned about the time-delay factor with perl buffers and have
been unable to correct them following the advice of the FAQ(s) and

I'm hoping someone knows the trick to this.
In a Tk::Menu, that has say 4 levels deep of
cascading, how would I grey out something like
the "Cascade 4 Level 4 Choice 2" under Selections?

I'm using ROtext widget in my application. Now, it accepts width in
the charatcter.
At one time, I try to get width of the ROtext, but it gives me the
width in pixels.
