match 2d mode to Window

[white waluigi]

I'd like to make a little 2d game with lwjgl and Opengl.
The Problem is, that whenever i resize the Window, the content won't resize and just staysthe old size.
Thats my current code:
I just can't see the fault.

import org.lwjgl.LWJGLException;
import org.lwjgl.opengl.Display;
import org.lwjgl.opengl.DisplayMode;
import org.lwjgl.opengl.GL11;
 
public class QuadExample {
 
    public void start() {
        try {
	    Display.setDisplayMode(new DisplayMode(800,600));
	    Display.create();
	    Display.setResizable(true);
	} catch (LWJGLException e) {
	    e.printStackTrace();
	    System.exit(0);
	}
 
	// init OpenGL


	System.out.print(Math.sqrt(4));
	while (!Display.isCloseRequested()) {
		GL11.glMatrixMode(GL11.GL_PROJECTION);
		GL11.glLoadIdentity();
		GL11.glOrtho(0, Display.getWidth(), 0, Display.getHeight(), 1, -1);
		GL11.glMatrixMode(GL11.GL_MODELVIEW);
	    // Clear the screen and depth buffer
	    GL11.glClear(GL11.GL_COLOR_BUFFER_BIT | GL11.GL_DEPTH_BUFFER_BIT);	
		
	    // set the color of the quad (R,G,B,A)
	    GL11.glColor3f(0.5f,0.5f,1.0f);
	    	
	    // draw quad
	    GL11.glBegin(GL11.GL_QUADS);
	        GL11.glVertex2f(10,10);
		GL11.glVertex2f(Display.getWidth()-10,10);
		GL11.glVertex2f(Display.getWidth()-10,Display.getHeight()-10);
		GL11.glVertex2f(10,Display.getHeight()-10);
	    GL11.glEnd();
 
	    Display.update();
	}
 
	Display.destroy();
    }
 
    public static void main(String[] argv) {
        QuadExample quadExample = new QuadExample();
        quadExample.start();
    }
}

You aren't setting the viewport. You have to set the viewport to tell OpenGL where it should be drawing. You use the glViewport command which takes 4 params: x, y, width, height. x and y are relative to the position of the Display so every time the display gets resized, you need to call glViewport(0, 0, Display.getWidth(), Display.getHeight());
