java Frame

watsgone

ey,

I have a java problem, I know its probably simple but bear with me.

I have a Jframe that I want to divide up into different panels.

example:
public MainFrame(){

super("The Text System " );
setSize(900,700);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setVisible(true);
}
The panels contain labels, buttons etc.
example of a panel:
public DetailPanel(){
super();
setPreferredSize(new Dimension(1,0));
setVisible(true);
//this.setBorder(new TitledBorder("Details"));

dtxtarea.setLineWrap(true);
dtxtarea.setWrapStyleWord(true);

add(rptDetail);
add(dScroll);
add(save);
}
I want to keep the panels separte and just call them in the Jframe to display them.
ie
in the main frame do this
DetailPanel detailsP= new DetailPanel();
to display the panel
I am going wrong some where.
Any help would be great.

You need something like the following:

public class MyFrame extends JFrame{


MyFrame (){

JPanel myPanel=new JPanel();
//ad stuff to panel

getContentPane().add(myPanel, BorderLayout.CENTER);

setVisable(true);
}
}
You may want to look at different Layout managers to arrange the panels nicely in the Frame also.
The default layout for a JFrame content pane is BorderLayout so you can add panels to
BorderLayout.CENTER
BorderLayout.NORTH
BorderLayout.SOUTH
BorderLayout.EAST
BorderLayout.WEST

Nothing stopping you creating a separate class (.java file) for each JPanel

public class DetailPanel1 extends JPanel{
     public DetailPanel1() {
         init();
     }

     private void init() {
        // Setup your panel here
     }
}

The in the main class do exactly as your example

DetailPanel1 panel1 = new DetailPanel1();
