Post more complete code. You might be missing a grid() (which is better than
pack()).

OK, here's the panedwindow code


horizsplit = TkPanedWindow.new(parent) {
orient 'vertical'
}
horizsplit.add(left)
horizsplit.add(right)
horizsplit.pack( 'fill' => 'both' )


Its failing saying that

undefined local variable or method `left' for #<MainGUI:0x403949e8>
(NameError)

Thanks
Nigel

Thanks for that, it works a treat. Please excuse my elementary ignorance
but I'm trying to teach myself some programing and am new to everything and
trying to piece it together from what documentation there is.

Thanks again
