Tab Key For Switching Input Boxes Not Reliable

[danieldresser]

A few issues that came up in some brief testing:

• when it does work, it usually goes in the wrong order ( Tab goes up, Shift Tab goes down )
• focus is often lost, I suspect it is tabbing to something that isn't visible
• you can tab to the script editor, at which point continued presses of the tab key type tab characters into the script editor instead of tabbing
• if I create a "Displays" global, and add an interactive beauty display to it, and click in the first text field, the tab order is:
  • next two fields correctly
  • something invisible or that doesn't show highlight
  • it then progresses backwards through the remaining parameters
  • it then gets stuck inside the quantize widget, and keeps looping through the same 4 things

I think this might be at least partially caused by the slice insertion implementation in ListContainer.setitem, because it inserts widgets backwards.

This seems to manifest in jabuka too.

I'd expect it to manifest in all the Gaffer apps. Since we're down to just 2 high priority tickets left for this milestone, would it be worth promoting a few of the mediums? I feel like this is a good candidate for needing done more than many of the others...

I'm just having a look through now to see what might be best tackled next - was thinking this might be a good one as it does have wider benefits.
Feel free to pick it off when you get the chance.
