Detailed Description

Key Handler Class, handles all of our KeyFunctions, which do not belong to camera control (this are handled by FPSCameraManipulator)

Controls:

                   C       = Toggle WireFrame Mode On/Off
                 LClick    = Interact
                 Shift+1   = Toggle programs

brtr::BaseInteractionCallback * brtr::KeyHandler::modifyText ( bool  show )

private

Shows the InteractionMessage on screen, if there is an InteractionObject beneath the mouse (e.a center of screen)

Parameters

to	show or not show the text, that is the question

Returns

the BaseInteractionCallback associated with the interactionObject, if any, null else;

void brtr::KeyHandler::mouseIntersection ( osgGA::GUIActionAdapter &  aa )

private

Checks, if under the mouse (e.a center of screen) is an interact-able object (e.a geometry)

Parameters

aa	GUIActionAdapter for getting the camera , to whom the LineIntersectionVisitor will be attached to
