Adding a Polyline drawing to a tab

[CirKuT]

Hello everyone,

I have a quick question. Im practicinf with 2D graphics and Netbeans and I have a quick question. I have created a simple GUI with 5 tabs. Nothing special at all. I also have a spiral drawing that I created with Polyline.
I want to put the spiral into the fourth tab but Im unsure how to do this. Any suggestions? Posted below are my 3 classes in this order. 1)Launcher 2)The GUI 3)The spiral drawing

package JTabbedPaneFrame;

import javax.swing.JFrame;
/**

public class JTabbedPaneDemo
{

public static void main(String args[])
{

JTabbedPaneFrame tabbedPaneFrame = new JTabbedPaneFrame();
tabbedPaneFrame.setDefaultCloseOperation(JFrame.EX IT_ON_CLOSE);
tabbedPaneFrame.setSize(380, 200);
tabbedPaneFrame.setVisible(true);

}// end method main
}//end class JTabbedPaneDemo





package JTabbedPaneFrame;

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

public class JTabbedPaneFrame extends JFrame
{
//set up GUI
public JTabbedPaneFrame()
{

super ( "JTabbedFrame Demo" );

//create JTabbed Pane
JTabbedPane tabbedPane = new JTabbedPane();

//set up panel and add it to JTabbedPane
JLabel label1 = new JLabel("panel one", SwingConstants.CENTER);

//creates first panel
JPanel panel1 = new JPanel();

//add label to panel
panel1.add( label1 );
tabbedPane.addTab( "Tab One", null, panel1, "First Panel");

//sets up the second panel
JLabel label2 = new JLabel("panel two", SwingConstants.CENTER);

//create second panel
JPanel panel2 = new JPanel();

//set background color to yellow
panel2.setBackground(Color.YELLOW);

//addd label to panel
panel2.add(label2);
tabbedPane.addTab ("Tab Two", null, panel2, "Second Panel");

//sets up third panel
JLabel label3 = new JLabel( "panel three", SwingConstants.CENTER);

//creates third panel
JPanel panel3 = new JPanel();

//use border layout
panel3.setLayout(new BorderLayout());
panel3.add(new JButton("North"), BorderLayout.NORTH);
panel3.add(new JButton("West"), BorderLayout.WEST);
panel3.add(new JButton("East"), BorderLayout.EAST);
panel3.add(new JButton("South"), BorderLayout.SOUTH);
panel3.add(label3, BorderLayout.CENTER);
tabbedPane.addTab("Tab Three", null, panel3, "Third Panel");

//set up panel and add it to JTabbedPane
JLabel label4 = new JLabel("panel four", SwingConstants.CENTER);

//create fourth panel
JPanel panel4 = new JPanel();

//add label to panel
panel4.add( label4 );
tabbedPane.addTab( "Tab Four", null, panel4, "Fourth Panel");
SpiralDrawing spiralDrawing = new SpiralDrawing();
panel4.add(spiralDrawing);
//set up panel and add it to JTabbedPane
JLabel label5 = new JLabel("panel five", SwingConstants.CENTER);

//create fourth panel
JPanel panel5 = new JPanel();

//add label to panel
panel5.add( label5 );
tabbedPane.addTab( "Tab Five", null, panel5, "Fith Panel");


//add JTabbedPane to Frame
add(tabbedPane);

}//end JTabbedPaneFrame constructor
}//end class JTabbedPaneFrame

Have a look at the various layouts available at the Sun Swing layout tutorial as they will allow you to add multiple components to a JPanel and help you position them where you want to. One in particular that is useful here is the BorderLayout which will solve your problem like so:

    JLabel label4 = new JLabel("panel four", SwingConstants.CENTER);
    JPanel panel4 = new JPanel(new BorderLayout()); // add borderlayout here
    panel4.add(label4, BorderLayout.NORTH);
    tabbedPane.addTab("Tab Four", null, panel4, "Fourth Panel");
    SpiralDrawing spiralDrawing = new SpiralDrawing();
    panel4.add(spiralDrawing, BorderLayout.CENTER);

You can find the tutorial on this here: How to Use BorderLayout (The Java™ Tutorials > Creating a GUI with JFC/Swing > Laying Out Components Within a Container)
