How do you pass along a mouse event?

[Knute Johnson]

How do I pass along a mouse event that is collected in a MouseListener
to the parent component? Component.processMouseEvent() is protected so
you can't call that from the listener.

I have a panel that has a bunch of components on it that I detect mouse
clicks on. The panel is in a dialog. I want to signal the dialog to
close after the user clicks on the on one of the components and that
mouse event is processed.

Would you use a PropertyChangeListener for this and call
firePropertyChange() from the mouse listener?

Thanks,

It is theoretically possible to create a new mouse event and dispatch
that. See 1.5, er, javax.swing.plaf.basic.BasicInternalFrameUI for some
long and tortuous code to attempt that.

Probably a better way is not to interfere with the event (add mouse
listeners interferes, which is dumb design, but the way it is). In a
trusted environment you can use an AWTEventListerer Toolkit. In an
untrusted environment you will need to push an EventQueue (which also
allows you to intercept the event).

Usually you would listen to an event that makes sense to the component
in question. An ActionEvent or perhaps a ListDataEvent.
