Hello forum, Vaironl here.

I have a little problem, in a fairly big piece of code.

I'm making a recipe application, which is working fine, but there is one minor error. If I minimize the screen and restore it, some of the components inside it are somehow re sizing of the JFrame. any ideas here is the code.

Main class/Frame

import java.awt.Color;
import java.awt.Dimension;
import java.awt.FlowLayout;
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import java.awt.GridLayout;
import java.io.ObjectInputStream.GetField;

import javax.swing.*;

public class Frame {
	private static final int WIDTH=900;
	private static final int HEIGHT=800;
	private static JFrame frame = new JFrame("Recipe Application");
	private static final Panel panel = new Panel();
	public static void main(String[] args)
	{
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		frame.setSize(WIDTH,HEIGHT);
		frame.setLayout(new FlowLayout(FlowLayout.LEFT));
		frame.add(panel);
		frame.setResizable(false);
		frame.setVisible(true);
		frame.setLocationRelativeTo(null);
		
		
	}

}
