屏幕宽高 LWJGL

Question

I am making a simple LWJGL program and would like to be able to use the width and height of the window. I can do it now I just have to use Display.getDisplayMode().getWidth() but I have seen people use just Display.getWidth()

So my question is why is this happening, and what do I need to change for it to just use Display.getWidth();

Answer 1

The latest version of LWJGL according to the documentation says that it has a static method called getWidth. Make sure you're invoking it by it's class name and not on an object - as it's static.

Answer 2

In LWJGL, there are two display classes, one in:

• org.lwjgl.opengl

and the other in:

• org.lwjgl.util

If you import from the opengl package, you don't need getDisplayMode() and if you import from the util package you do.
