While it's easy to bind mouse events to a listbox, I haven't managed
to bind keyboard events to it. In a current project I have a listbox
and I want my users to be able to scroll through it using common keys
like <Up> and <Down>. However, binding them to the listbox, as done
above, does not work; I don't know why.
If I do a bind_all, it does work, though. Unfortunately, this is not
the right way to do it; I have another window with a ScrolledText
widget, and if I scroll there, the listbox scrolls too, due to the
bind_all effect!
Experimenting, I also tried binding "<Down>" (etc) to all widgets in
the current frame, which doesn't work either.
So my obvious question is, how can I bind keyboard events to a
listbox without having to use bind_all?
