We are trying to build some muti-touch windows application on touchsmart tx2.

The current driver we download from website is for win7, and we can build some simple apps with win7 api already.

However, we still want to build our own applications without win7, so, we DO NOT some low level apis which can directly provide point positions.

 We are looking for something like below:

         /*Point Info

         *

         *x1,y1,x2,y2 is rectangular coordinate as dragging rectangle by mouse

         */

         typedef struct _PointData

{

                  WORD x1;

                  WORD y1;

                  WORD x2;

                  WORD y2;

         }

         //Define call back method

         typedef  void (WINAPI *MultiTouchCallback) (const PointData *, int);

         //Do not receive any touch points

         int UnRegisterDataReceivedCallback();

         //Begin receive touch points

         int RegisterDataReceivedCallback(MultiTouchCallback);
