如何捕获JFrame / Swing中的所有鼠标事件？
问题描述：
我有一个JFrame，它有大量更改的子组件。 （很多层）有没有办法为所有鼠标事件添加一个监听器？类似于KeyEventDispatcher？
I have a JFrame that has a large number of changing child components. (Many layers) Is there any way to add a listener for all mouse events? Something like KeyEventDispatcher?

使用AWTEventListener过滤掉MouseEvents：
Use an AWTEventListener to filter out the MouseEvents:
long eventMask = AWTEvent.MOUSE_MOTION_EVENT_MASK + AWTEvent.MOUSE_EVENT_MASK;
Toolkit.getDefaultToolkit().addAWTEventListener( new AWTEventListener()
{
public void eventDispatched(AWTEvent e)
{
System.out.println(e);
}
}, eventMask);
