lable hides image in frame
Hello
I am trying to display a label over a chart but the lable hides the chart
Can anyone help me see what parametres I have to set to stop this from happening?
super("Chart");
JLabel label;
chart ch = new chart();
add(ch);
add(new Label("Hi There!"));
setLayout(new FlowLayout(FlowLayout.CENTER, 10, 10));
setSize(400, 400);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE );
setVisible(true);
Thanks :-)

Don't add components directly to frame. Usejava.awt.Container contP = this.getContentPane();and add elements to containercontP.add(ch)contP.add(new Label("Hi There!"));PS. Use code formatting
H?br>I have tried your suggesstionBut when the code is run then the label still appears over the chart :-(
You may add components directly to a JFrame since it forwards the add() to the contentpane. Regarding your question, see my reply in the other thread you created.#PS Do not create multiple threads for a single question
@duckbill
try that:
import javax.swing.JButton;
import javax.swing.JFrame;
public class Forum extends JFrame {
public Forum(){
JButton b1 = new JButton("1");
JButton b2 = new JButton("2");
add(b1);add(b2);
setSize(200,200);
setDefaultCloseOperation(3);
setVisible(true);
}
public static void main(String[] args){
new Forum();
}
}
@duckbill again
sorry! There were the times where adding to content pane was not done directly to by JFrame.add() . Now getting the content pane does not work as well.
@OP
there You go:
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class Forum extends JPanel {
public Forum(){
JButton b1 = new JButton("1");
JButton b2 = new JButton("2");
add(b1);add(b2);
}
public static void main(String[] args){
JFrame frame = new JFrame("Forum");
frame.setContentPane(new Forum());
frame.setSize(200,200);
frame.setDefaultCloseOperation(3);
frame.setVisible(true);
}
}

You CAN use either
// JFrame frame
frame.getContentPane().add(...);
//OR
frame.add(...);
Btw it is not a good idea to extend JFrame or JPanel unless you are actually extending the behaviour of the class (e.g. doing custom painting). Just use the classes as they are.

Don't mix Swing and AWT components. This will cause problems, like
components that don't layer properly, which sounds like your problem.
If this doesn't fix you problem, post a tiny example program that demonstrates
your problem.
H?
Yes that is my problem that i think my chart is being hidden by my label
and I am getting a little confused as to why and how to order the two items so this does not happen
Thanks for the advice
see code below
import java.awt.*;
import javax.swing.*;
public class test extends JFrame {
/** Creates a new instance of Chart */
public test() {
super("test");
JLabel label;
chart ch = new chart();
add(ch);
add(new Label("Hi There!"));
setSize(400, 400);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE );
setVisible(true);
}
public static void main(String[] arguments) {
test pie = new test();
}
}
Which of the previous posts You DIDN'T understand or maybe I should ask which of them HAVE YOU READ?Try to pay attention to what others are trying to tell you or You won't receive any futrher help.
Don't mix Swing and AWT components.Do you understand that statement?

No dispute there ... but that's not the pblm here - it's Layout issue. JFrame and Frame are by default BorderLayout - I know you know this BTW and so default the Label added later overlays the CENTER of the BorderLayout ...
import java.awt.*;
import javax.swing.*;
public class MixedReactionsFrame extends JFrame {
/** Creates a new instance of Chart */
public MixedReactionsFrame() {
super("MixedReactionsFrame");
Container c = getContentPane();
JLabel label;
chart ch = new chart();
ch.setPreferredSize(new Dimension(110,110));
c.add(ch);
c.add(new Label("Hi There!"),BorderLayout.NORTH);
setSize(400, 400);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE );
setVisible(true);
}
private class chart extends JPanel {
public void paint(Graphics g) {
//public void paintComponent(Graphics g) {
//super.paintComponent(g);
g. setColor(Color.BLUE);
g.fillRect(0,0,100,100);
}
}
public static void main(String[] arguments) {
MixedReactionsFrame pie = new MixedReactionsFrame();
}
}
Hello everyoneThanks for all the helpful comments and pointersAnd yes I do now understand (after some reading) the difference between AWT and SWINGAnd I now see my problem lay in my poor understanding of how to layout the frameAgainThanks :-)
