Widget.sinkEvents介绍

[英]Overridden to defer the call to super.sinkEvents until the first time this widget is attached to the dom, as a performance enhancement. Subclasses wishing to customize sinkEvents can preserve this deferred sink behavior by putting their implementation behind a check of isOrWasAttached():

@Override 
public void sinkEvents(int eventBitsToAdd) { 
if (isOrWasAttached()) { 
/ 
 * customized sink code goes here  
 */ 
} else { 
super.sinkEvents(eventBitsToAdd); 
} 
}
