Dragging objects with the mouse

[LukasBanana]

Hi there,
in all Bullet Physics Demos you can drag the physics objects with the mouse. But I can't find the code where this is implemented.
I can imagine that this is in a 'common' or 'base' part for the demos because it is used in every demo.
Thanks for help in advance

Have a look in DemoApplication.cpp (under demos opengl for example) - you're looking for the pick constraint code.
