Scrollbars should include far right/bottom pixel column/row (Fitt's Law)

Description

Scrollbars, by necessity for small screens, are small in sugar. But we are not utilizing the right-most pixel as part of the scrollbar. As cited in the Sugar HIG[0] states that screen corners and edges are control interfaces that are highly usable according to Fitt's Law[1].

Here is the current interaction when someone wants to scroll down in an activity:

  1. User moves cursor to the far right scrollbar.
  2. User overshoots by one pixel to the right-most pixel (Y-max)
  3. User clicks and drags the cursor up or down.
  4. Sugar doesn't respond.

Ideally, this would happen:

  1. User moves cursor to the far right scrollbar.
  2. User knows and expects the Y-max to be clickable as scrollbar
  3. User clicks and drags.
  4. Sugar scrolls the window.

I was wrong. This isn't sugar-wide: it doesn't effect Journal or Help, but does effect Terminal. I will now log which activities this effects and which it doesn't so this bug can be reassigned.

Does:

  • Terminal
  • Abiword

Does Not:

  • Journal
  • Help
  • Chat

Not relevant:

  • Moon
