Dragoon235 Posted June 17, 2010 Report Share Posted June 17, 2010 If you are trying to enter a coordinate, aren't there easier ways to do that (numerics, sliders, knobs)? Because that would be like creating a "mouse control". You could build a control as either a typedef or an XControl or similar with an event structure that registered the position of mouse clicks. Or you could just use the event structure to register the position of the mouse on a click. You could also register pressing of the arrow keys, or create a key binding of the arrow keys to buttons on the front panel. Otherwise, you are getting into some tricky programming in regards to emulating 3D motion in a 2d front panel. If you mean to read from a physical track ball like a joystick, I think that involves some configuration on the OS side first such that it is not registered as the primary pointing device.
