I am trying to add 2 extended JPanels to a JPanel or a JFrame but both show up really tiny even if I set a size. The code is below; trial.java is the class that builds the GUI.
trial.java
import java.awt.Color;
import java.awt.FlowLayout;
import javax.swing.BoxLayout;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class trial {
public static void main(String args[]){
JFrame window=new JFrame();
window.setSize(1900, 800);
window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel content=new JPanel();
content.setLayout(new FlowLayout(FlowLayout.LEFT));
content.setBackground(Color.BLACK);
tile t1=new tile(new String[]{"arc","curve", "curve"}, new Color[]{Color.GREEN, Color.RED, Color.YELLOW});
//t1.setSize(100, 100);
content.add(t1);
content.add(new gridModel((0.7*1000)/21));
window.add(content);
//window.add(new gridModel((0.7*1000)/21));
//window.add(new tile(new String[]{"arc","curve", "curve"}, new Color[]{Color.GREEN, Color.RED, Color.YELLOW}));
//window.pack();
window.setVisible(true);
}
}

I have tried to use different layouts an setting the size of the panels but both extended panels show up as tiny squares. How do I increase the size of these extended JPanels?
