Problem with setBounds settings

[Jensen Ackles]

Hello,
I have a liite problem with my code
I created a window in which I do the following

pn JPanel = new JPanel ();
pn.setLayout (null);

Then I add in the other two JPanel

jpne JPanel = new JPanel ();
jpne.setBounds (0,0,200,400);
jpne.add (new Panopticon ());
pn.add (jpne);

jpand JPanel = new JPanel ();
jpand.setBounds (200,0,400,400);
jpand.add (new pngr ());
pn.add (jpand);

pngr () and Panopticon () retrieve the width and height of their JPanel then displayed in the console. They look like:
public class pngr extends JPanel (
public void paintComponent (Graphics g) (
lrg this.getWidth = int ();
hutfen this.getHeight = int ();
System.out.println (lrg + "" + hutfen + "\ n");

Why setBounds settings are they not sent?
Thanks in advance.

Hello,
I think by default, JPanel uses FlowLayout that respects the "Preferred size". You can try to BorderLayout:

pan JPanel = new JPanel (new BorderLayout ());

If you need more information on the swing concepts and all the classes and the methods which are included in the swing that is the awt package then you can visit the sun's official site and there you can find the API on the same.

Hello,
I also have a similar kind of a problem with me. I placed "pn.setLayout (null)" in order to put myself elements, it seemed the easiest way to manage two objects. I followed your advice and added a BorderLayout and preferredSize. Unfortunately I get exactly the error there. If you have any alternative method or class which I can use to do the same, then it would be more helpful. Thanks in advance.

Hello,
I have tried the following example, please check if I am in the correct direction

public class mnprg (
public static void main (String [] args) (
int wd = 200;
int hg = 150;

jfrm JFrame = new JFrame ();
jfrm.setSize (wd, hg);
jfrm.setLocationRelativeTo (null);
jfrm.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);

jpn JPanel = new JPanel ();
jpn.setBounds (0,0, hg, hg);
jpn.add (new PanPgr ());

jfrm.setContentPane (jpn);
jfrm.setVisible (true);
}
}

Hello,
I am new to this concept but I have a code that could interest you, take a look at the code
Here is the part of the code

public class prg extends JPanel (
public void paintComponent (Graphics grp) (
System.out.println (grp.getClipBounds ());
grp.setColor (Color.BLUE);
grp.fillRect (0, 0, 100, 100);
}
}

Hello,
Check out the updated that is the modified form of the above code

Public class prg (

    Public static void main (Final String[] Args) (

        int w = 200;

        int hg = 150;

        JFrame jfrm = new JFrame ();

        jfrm.setSize (w, hg);

        jfrm.setLocationRelativeTo (null);

        jfrm.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);

        JPanel jpnl = new JPanel (new BorderLayout ());

        jpnl.add (new prg ());

        jfrm.setContentPane (jpnl);

        jfrm.setVisible (true);

    }

}

class prg extends JPanel (

    @ Override

    protected void paintComponent (Final Graphics grp) (

        System.out.println (grp.getClipBounds ());

        grp.setColor (Color.BLUE);

        grp.fillRect (0, 0, 100, 100);

    }

}
