how to get the window’s size (height and width) ?
depends on your OS
in windows, you can use a number of functions for determining this:
also, during a WM_SIZE message
width = LOWORD(lParam)
height = HIWORD(lParam)
if you are using glut then you can set the initial window size with glutInitWindowSize and then use glutReshapeFunc to set up a reshape handler that will keep track of window reshape events.
