Hello All, I have a need to determine when the mouse is moved on a Linux system. Ultimately, my Java program will call a C program that can determine and notify Java when the mouse pointer has been moved. I have been looking at using XLib and use the XGrabPointer but am having trouble satisfying all of the XGrabPointer parameters and am new to the XLib programming world. Does anybody have a sample program that uses XGrabPointer to determine mouse activity? Any help is greatly appreciated. Thank You, Dallas dallas_glidewell@xxxxxxxxxxx __________________________________________________ Do You Yahoo!? Get Yahoo! Mail - Free email you can access from anywhere! http://mail.yahoo.com/
