Please add support for mouse wheel events!


Posted on Mar 23, 2007 by Massive Rhino

Found in GWT Release: 1.3.3

Detailed description:

I think GWT should have support for mouse wheel events - the Event class should be modified to contain a new enumeration value for the mouse wheel and support added to the respective DOM implementations to achieve this.

There should be a way to capture the event, but also a way to get the delta value for the scroll wheel from the Event object.

Workaround if you have one:

Create JSNI methods to attach the mouse wheel event to a widget - not hard to do, but GWT was made just so that developers shouldn't have to do this!

Current decision is to use a MouseWheelVelocity container to support the future addition of X-axis scrolling and to normalize the velocity. knorton has been handling review/feedback so far.
