How To Stop Flicking JPanel Component?

[Tom Finn]

The code below flickers when I update. I've heard about double buffering but no idea how it works/how I would implement that.

import javax.swing.JPanel;
import java.awt.Graphics;
import java.awt.Graphics2D;

public class VisualFrame extends JPanel {
	
	public static RuntimeConverter x = new Converter();
	
	public void paintComponent(Graphics g) {
		Graphics2D g2 = (Graphics2D) g;
		x = new Converter();
		//Draw it
		display.draw(g2);
	}
	
	public Converter getConverter() {
		return x;
	}
}

Go through the JPanel constructors; there is one with a boolean parameter. All you have to do is pass true to that.
I am not certain that is the correct solution, but double-buffering is the first thing I would try.

It would seem to suggest that missing out the boolean flag will give it a double buffer, if you look at the JPanel ←link documentation. But it is still worth a rty.

what is this doing in paintComponent?
x = new Converter();

Good idea. I tried it but it didn't work though.

I just spotted that myself. (The program is quite large).

Removed it.
