Create a MouseOutEvent. You'll want to modify to fit your circumstances.
This includes locating "tb".

final Button tb;

/*
* Synthesize and fire an event
*/
final
NativeEvent evt = Document.get().createMouseOutEvent(1 /* detail */
, 0 /* screenX */
, 0 /* screenY */
, 0 /* clientX */
, 0 /* clientY */
, false /* ctrlKey */
, false /* altKey */
, false /* shiftKey */
, false /* metaKey */
, NativeEvent.BUTTON_LEFT /* button */
, null /* relatedTarget */);

tb.getElement().dispatchEvent(evt);
