In OSG2.2 I'd like to find the 'real' x,y location of the mouse cursor. If my
window is 640x480, then the value for x should be between 0 and 639, while y
should be from 0 to 479. I need the x,y values in this form so that it can be
injected into CEGUI correctly.
The GUIEventAdapter has protected
osgWidget does this, and converts the origin to the upper-left instead
of lower-left in the WindowManager object just using getX/getY. They
have never returned normalized coordinates in my usage... but perhaps
I've been benefiting from a bug all along...?

How about:
float fMouseX = ((ea.getX() + 1.0)*0.5) * (float)ea.getWindowWidth();
float fMouseY = ((ea.getY() + 1.0)*0.5) * (float)ea.getWindowHeight();

Hello Donald,
I actually tried something along the lines of what you wrote:
int my_x = (int) ( ((ea.getX() + 1.0) / 2.0) * 640.0 );
int my_y = 480 - (int)(((ea.getY() + 1.0) / 2.0) * 480.0);
Your lines basically do the same thing (except flip the y axis). However, my
problem is that the

Again, I never get the normalized values in osgWidget (and haven't since
I began writing it). This has to have something to do with the kind of
camera the event appears within, as looking through the code I see that
the event{X,Y} values are calculated
I found a workaround to my problems, my thanks to Jeremy for pointing a few
things out.
If I make the following setting:
camera-setAllowEventFocus(false);
Then in Viewer::eventTraversal() this will avoid setCameraWithFocus(camera);
