This is a qooxdoo bug. I submitted a bug report there last week. If it doesn't get fixed before I have time to work on it, I'll see if I can figure out why that widget is not passing scroll wheel events through.

Assigning to me.

I tested this as well and believe I know what is causing it.

The qooxdoo ribbons are capturing the mouse wheel properly, but for horizontal scrolling.

Steps to Reproduce:

• Resize the window horizontally enough so all the ribbon items can't fit in the ribbon at the same time. You should see the ribbon left and right scroll buttons appear.
• Place your mouse over the ribbon and scroll horizontally. My mac has a two horizontal scroll using the touchpad, or if using my mouse in I can hold down shift with the scroll wheel to scroll horizontally. I believe windows may be shift as well.
• Notice the scrolling working correctly in the ribbon.

I believe the best solution here is to disable the ribbon from capturing the mouse events at all. When the horizontal width is great enough and all the ribbon items fit on the screen, the mouse scrolling appears to the user to be broken. Even when the ribbon can be scrolled, the functionality of page scrolling vertically is non intuitive to the user when their mouse is accidently over a ribbon.

Yes. This is a qooxdoo bug which I have already reported. The mouse wheel events should not be captured by a horizontally-scrolling widget; only by a vertically-scrolling widget. Those ribbons are horizontally-scrolling, so the mouse wheel events should be passed through.

Fixed in qooxdoo. Incorporated into alpha006.
