jme3, deactivate camera movement in SimpleApplication

Hi,

if I use SimpleApplication for my app, how can deactivate the camera movement with keyboard and mouse (fast and painless)?

Thank you.

In addition, how can I deactivate the FSP and stat counter in the lower left edge?

Camera: flyCam.setEnabled(false);

FPS/Stats: guiNode.setCullHint(CullHint.Always);
