 We use rubber band mode to select cloudpoint,Press x or X to activate this mode,It do work.
Users often forget to press x again to close rubber band mode, then shift to another frame, drag the window,click or move mouse will cause crash .
The develop envirement is VS2010 +pcl 1.7 , windows 7, 64bit .
So we want to close the rubber band mode by simulate 'x' press automantically ,
keybd_event(VK_X,0,KEYEVENTF_KEYUP,0);
But can not close the rubber band mode.
Is there any better method to solve this problem?
