Need help with using layout.

[Willie Tsang]

My problem is, I want my Jlabel to appear at the 0,0 location, as coded in the grdibagconstraints, but it appears in the center if i run this code. I already read alot of the apis, but it didn't help. Please help. Thanks

public class JFrameTester {
	public static void main(String[] args) {
		MyJFrame myFrame=new MyJFrame();
		myFrame.configure();
		
	}

}

import java.awt.Color;
import javax.swing.JFrame;

public class MyJFrame extends JFrame {
public MyJFrame(){
	super("Recursive Shape");
}
public void configure(){
	setSize(500,500);
	setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
	LogSpiralPanel panel=new LogSpiralPanel();
	add(panel);
	setBackground(Color.WHITE);
	setVisible(true);
	}
}

import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import javax.swing.JComponent;
import javax.swing.JLabel;
import javax.swing.JPanel; 
public class LogSpiralPanel extends JPanel{
	public LogSpiralPanel(){
		layouting();
	}
	public void layouting(){
		GridBagLayout gridBag=new GridBagLayout();
		setLayout(gridBag);
		GridBagConstraints c=new GridBagConstraints();
		c.weightx = 0.5;
		c.gridx = 0;
		c.gridy = 0;
		g=c;
		addLabel();
	}
	public void addLabel(){
		JLabel label=new JLabel("test");
		label.setOpaque(true);
		add(label,g);
	}
private GridBagConstraints g;
}

add the additional 2 lines

c.weightx = 0.5;
c.weighty = 0.5;//<---
c.anchor = GridBagConstraints.NORTHWEST;//<---

Thanks for reply, but when i change the values of
c.gridx = 0;
c.gridy = 0;
it stays at NORTHWEST.
is there a way to change its location according to the x,y?

Could be wrong (usually am), but I have a sneaking suspicion you can't just 'place'
components here-and-there in GBL e.g. at 1,1 with no other components.

you may need to add a JPanel at 0,0 then use an appropriate layoutManager
for the panel to add your label where you want it.

Thanks alot for your post. Ill confirm that by reading the api, and mean while ill try different layouts. Thanks.

That word is "I'll" and is short for "I will" or "I shall"
