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

Do you really want to set "vertical"?
If "orient" option is "vertical", widgets are stacked vertically
in the panedwindow.
The words, "horizsplit", "left" and "right", don't denote "vertical stack".

horizsplit.add(left)
horizsplit.add(right)
horizsplit.pack( 'fill' => 'both' )

You must give widgets for TkPanedWindow#add.
For example,

  horizsplit = TkPanedWindow.new(parent, :orient=>:horizontal){
    add(TkListbox.new(horizsplit).insert(:end, 'lbox1'))
    add(TkListbox.new(horizsplit).insert(:end, 'lbox2'))
    add(TkListbox.new(horizsplit).insert(:end, 'lbox3'))

    pack(:fill=>:both, :expand=>true)
  }
  horizsplit.panes.each_with_index{|lbox, idx| lbox.insert(:end, idx)}

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
Nigel
