openFrameworks wrapper addon for Ryan C. Gordon's manymouse library.

With this addon you can easily read values from multiple mouse or trackball devices.

Instructions:

1. Add the ofxManyMouse to your project

2. #include "ofxManyMouse.h" in testApp.h

3. let testApp extend ofxManyMouse like this: 
       class testApp : public ofBaseApp, public ofxManyMouse { 

4. Add one or more of the following functions to testApp.h
       void mouseMoved(int device, int axis, int value);
       void mouseScroll(int device, int axis, int value);
       void mousePressed(int device, int button);
       void mouseReleased(int device, int button);
       void mouseDisconnect(int device);

5. Implement the function(s) in testApp.cpp
       void testApp::mouseMoved(int device, int axis, int value) {
          //do something with the values
       }

Good luck!
