When, where, and how is a GUI event created for a Swing component?

Question

Somebody please help me with this issue !
Heavy weight (AWT) components such as JFrame, JDialog, JApplet, and JWindow have
native peers. As I understand, the senario of event creation for such heavy components
is something like follows:
1. A mouse click happens in a heavy component.
2. The native platform (i.e. the OS) captures the mouse click event and
store it as a native event somewhere in the system.
3. java.awt.EventDispatchThread gets this message and translates the native message
into an AWTEvent. When creating the AWTEvent, AWT actually looks up a hashtable
for the reference to the heavy component from the reference to the native window.
The hashtable stores all the pairs of heavy components and their native peers ever
created during the session. Now the AWTEvent includes a reference to the "source"
component that generates the event.
4. java.awt.EventDispatchThread dispatches the AWTEvent to the heavy component
for furture processing.
As for light weight (Swing) components such as JButtion, no native peers are attached.
So, there is no mapping from native peers to light weight components.
After a mouse click happens over a JButton, how, when, and where is the corresponding
event created and finnally routed to JButton. Could somebody give a sketch of the
senario? Thanks a lot.

Basically for Swing components, it would have to figure out based on the size and location of the components which one the click happens in. One could simply know that this panel is so big and it has such and such components in it which are however big and located at whatever point. It's a matter of digging down through components to find the lowest (or would it be highest) one.
