I have been working with scene2d.ui stage
this is the stage initialization
OrthographicCamera cam = new OrthographicCamera();
cam.setToOrtho(true);
ScreenViewport SV = new ScreenViewport(cam);
stage = new Stage(SV);
the reason I have cam.setToOrtho(true);
is because I want the 0,0 to be up in the top left
the text input works if it is given focus at first
but I can not click on it to give it focus
