Dear All,
I have some problem with Batik Mouse Click event . Document of
MouseEvent.getButton() says
return value of 0 indicates left button, 1 for middle button, 2 for right
button. I have wrote a simple
java file to test it, however the getButton method always returns me 1. Does
anyone know if I did
something wrong?
Thank you very much.
Kind regards,
Qian
Here is the code, It's also in the attachment
