Hi to everybody, it's still me with the "buttons in the scene" thing; i tried to use the osgGUIsh but it wasn't very clear to me... i'm quite a novice with osg and my code understanding doesn't arrive there. Anyway I saw the function setEventCallback, getEventCallback and I thought i could maybe use that. My problem is: I succeded to modify osgpick example and import there a model in .3ds format. I would like to modify the geometries of osgpick in the way that clicking on them I can control the texture and the lighting of the model. Normally everybody is doing it with the keyboard, but I'm making it more difficult for myself because I wanna use this on a touchscreen. Does anybody know if these functions are right for me? and if yes, could anybody explain me how to write them correctly in the code?

thanks

P.S. thanks for your understanding my knowledge limits with osg...

Gianlup
