Abstract

This TIP proposes a change to Tk's Events such as to support new features of modern pointer devices (mice) in a platform-independent way.

Rationale

Modern pointing devices (mice) do have more controls beyond the standard three buttons and one-dimensional scrolling gadget. They often have any of these as well:

  • Tilt-able scroll wheel

  • A second wheel for horizontal scrolling

  • A scroll-ball rather than a scroll wheel (see Apple's "mightymouse")

  • Additional "forward" and "backward" buttons

  • even more buttons...
