first JLayeredPane
Hello. I磎 trying to do my first JLayeredPane but as always it dosent work the first time. Right now I磎 getting the error:
"cannot find symbol - method setLayer(View,java.lang.integer,java.awt.point)"
setLayer :: (Component c, int layer, int position)
my code:
setLayer(view, new Integer(1),0);
I guess it磗 my "position"(0) who is wrong. But how should the last arguemnt "position" be set?

I try to post the full code:
import java.awt.*;
import javax.swing.*;
//View class
public class Main{
public static void main(String[] args){
JFrame f = new JFrame("title");
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.setSize(600, 500);
// creating 2 view classes/JPanels
View viewPanel1 panel1 = new viewPanel1();
View viewPanel2 panel2 = new viewPanel2();
// creating the layerPanel and adding the JPanels
JLayeredPane lp = new JLayeredPane();
lp.add(view);
lp.add(sview);
// the possition for the specified Panel
setLayer(view, new Integer(1),1);
setLayer(sview, new Integer(1),-1);
f.add(lp);
f.setVisible(true);
}
}

The posted code is not compileable.
If you really need help then you need to create a
[url=http://homepage1.nifty.com/algafield/sscce.html]Short, Self Contained, Compilable and Executable, Example
Program[/url] (SSCCE) that demonstrates the incorrect behaviour.
Don't forget to use the [url=http://forum.java.sun.com/help.jspa?sec=formatting]Code Formatting Tags[/url]
so the posted code retains its original formatting.

Thanks for reply. I磎 not very good at java and becouse of that I磎 not very good at SSCCE but I have done my best. Hope this will make it easier:
First JPanel Class:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class View extends JPanel{
public View(){
setPreferredSize(new Dimension(200,200));
}
public void paintComponent(Graphics g){
g.drawString("TEST",10,10);
}
}
Second JPanel class:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class stringView extends JPanel{
public stringView(){
setPreferredSize(new Dimension(100,100));
}
public void paintComponent(Graphics g){
g.drawString("TEST2",10,10);
}
}
Main class who gets the error:
"Cannot find symbol - method setLayer(View,java.lang.Integer,int)"
import java.awt.*;
import javax.swing.*;
public class Main{
public static void main(String[] args){
JFrame f = new JFrame("title");
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.setSize(600, 500);
// creating 2 view classes/JPanels
View panel1 = new View();
stringView panel2 = new stringView();
// creating the layerPanel and adding the JPanels
JLayeredPane lp = new JLayeredPane();
lp.add(panel1);
lp.add(panel2);
// the possition for the specified Panel
setLayer(panel1, new Integer(1),1);
setLayer(panel2, new Integer(2),-1);
f.add(lp);
f.setVisible(true);
}
}

hi
where do you think this part is?
// the possition for the specified Panel
setLayer(panel1, new Integer(1),1);
setLayer(panel2, new Integer(2),-1);
check i9t? where setLayer ?
# 5
ah. offcorse it should be
lp.setLayer(panel1, new Integer(1),1);
lp.setLayer(panel2, new Integer(2),-1);
thanks. But now nothing is showing up when running the program. Should not the "drawStrings" from the JPanels be shown? What have I missed?

Read the Swing tutorial on [url http://java.sun.com/docs/books/tutorial/uiswing/components/layeredpane.html]How to Use Layered Panes[/url] for a working example.

I just added an LayeredPane class to my program after many hours reading the tutorial. But once I succeded my "View" classes did no longer listen to my calls to repaint().
It draws everything up just fine when starting the program but dose never repaint even if I say it should repaint() in every method. Any idea what could be wrong?
