problem with renderArea.setEvnetCallback

[lzha022@xxxxxxxxxxxxxxxxx]

Hi,

I am using the function setEventCallback(...) of SoXtRenderArea because i want
to find the mouse position relative to the root window(XAnyEvent).
Now i have one problem:

After i call this function, i can neither rotate the image nor zoom in/out. I
guess it might because of the event callback. 

Can anyone please help me(email me) how to get rid of the event call back? or
resume the inventor function of rotating the image.

Regards

Alison
