Performance Improvement in IE
-----------------------------
Key: XAP-202
URL: http://issues.apache.org/jira/browse/XAP-202
Project: XAP
Issue Type: Improvement
Components: Widgets
Reporter: Rob Gagne
Provided 3 performance improvements:
1. New attribute on AbstractWidgetBridge that specifies whether mouse move/out
events are needed; defaults to false and is currently only set by ButtonBridge
which is the base for all of the widgets that change style.
2. Disconnect mouse move events when entering a component and reconnect them
when exiting
3. Switch IE to use mouseenter and mouseleave; these don't report leave until
actually leaving the component, mouseout reports when leaving a child element
These 3 changes dramatically improved cpu usage on IE
