JFrame window doesnt change background color

[Addez]

Hai!
In the following code, this "game" still have same background color.

class gameFrame extends JFrame implements Runnable { //
	public void run(){
		paintIt p = new paintIt();
		add(p);
	}
	public gameFrame(){
		
		
		
		//paintIt p = new paintIt();
		//add(p);
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		setSize(1000,1500);
		setTitle("Image test");
		getContentPane().setBackground(Color.WHITE);
		setVisible(true);
	}
}

why?
Im using a loop to update the images showed on it but Idk.. The frame is never white, always grey..
How do I fix it?

what is a paintIt object? Is it a JPanel? Realize that this is being repeatedly added to the JFrame's contentPane BorderLayout.CENTER and will cover up the original contentPane (unless it is not opaque). So it probably doesn't matter what color you set the contentPane as I'll bet you'll never see it.

BTW, I'm not sure that I'd do my animation this way. I'd use one JPanel as an animation panel and then swap images in the same panel rather than creating and adding a bunch of components. Your way seems somewhat inefficient to me and may risk running out of memory.

How do you run the program? Why is your JFrame a Runnable?

..and may risk running out of memory.

That has actually already happened before in one of the OP's thread which they abandoned.

My guess is it's a poor-man's Swing Timer. Better to use the real thing.

Sry, but the runnable part was just leftovers..
Heres the loop thingy:

class MyTimerActionListener implements ActionListener {
  	public void actionPerformed(ActionEvent e) {
  		if (!(Player.Y+Player.SizeY+2> 400)){
  			Player.CharVel[1] += 2;
  		} else {
  			Player.CharVel[0] = (Player.CharVel[0]/Player.Friction);
  		}
    	if (Player.Y+Player.SizeY> 400){
    		
    		Player.CharVel[1] = -Player.CharVel[1]/2;
    		Player.Y = 400-Player.SizeY;
    	}
    	Player.Y += Player.CharVel[1];
	   	Player.X += Player.CharVel[0]+Player.CharWalk[0];   
    	TestingArea.gf.repaint();
 	
  	}
  	
  	
}

ahh, furbarable is right, the jpanel covers up the jframe
so If i did setBackground on jpanel then it shows.
Niceeee!!
THanks all!

glad you have it solved. Again, you probably don't want to continually add components here.
