I believe you can find what you are looking for in my Gears Demo source code (there is a link in the How to create an Applet thread.  That applet demonstrates listening to the mouse in both hardware-rendering mode (when there is a child Canvas object) and in software-rendering mode (when there is not a child Canvas object).  If I understand your question properly, you would want to look at what I am using for hardware-rendering mode (i.e. getting the mouse events from the Canvas).  If you need further explanation after looking at the source code, let me know.

i consider the [hurry] to be quite impolite...anyway
I suspect this is an "adaptation" to the hard reality that on most forums nobody ever seems to answer anyone's questions.  Rest assured, alex, that the jPCT forum is not like most forums - 99% of the time questions are answered very quickly and very thoroughly (I would say 100% of the time, but I am relatively new myself, so I can't speak with 100% certainty).

thanks a lot for your words，
i just a new recruit,thank you again.As you said ,most forums nobody ever seems to answer anyone's questions,so I habitually added a "hurry".
I  apologize for this matter to EgonOlsen .

I don't understand your question and i consider the [hurry] to be quite impolite...anyway, whatever you do in a mouse- or keylistener, keep in mind that this is another thread than the rendering thread unless you are doing the rendering in paint/paintComponent, which you obviously don't do. If you rotate or modify an Object3D in any way directly into the listener's methods, you'll, without proper synchronization between the two threads, render inbetween states, which isn't what you want. I always suggest to set flags in the listeners that only signal what to do and do the actual operations in the rendering thread.

sorry ,i  did not expressed the problem clearly.
