Linking to a web page from a JApplet button

  Asked By: Lucina    Date: Aug 20    Category: Java    Views: 975
  

Can anybody help, I would like to put a button on a JApplet, like a 'Help'
button that opens a new web page when pressed, so that the original JApplet is
still visisble. can anybody suggest a way of doing this please?
This is my code for the JApplet

import java.applet.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.JComponent.*;

public class LogIn extends Applet implements ActionListener //implements
ActionListener
{
private Label nameLabel, passwordLabel;
private TextField nameField, passwordField;
private Button submitButton,bHelp;
private String helpfile;

public void init()
{
GridBagLayout gridbag = new GridBagLayout(); //initiates a new
gridbaglayout
GridBagConstraints constraints = new GridBagConstraints(); //assigns the
constraints
constraints.fill = GridBagConstraints.HORIZONTAL; //aligns the fill
setBackground(Color.white);

nameLabel = new Label("Enter User Name"); //Label constructer
constraints.gridx=0; //aligns label
constraints.gridy=0; //aligns label
constraints.weightx=1.0; //distributes space among columns
gridbag.setConstraints(nameLabel,constraints); //sets the constraints
nameLabel.setForeground(Color.black); //colour of the text
nameLabel.setFont(new Font("Serif", Font.BOLD,18)); //font type of text
add(nameLabel); //adds the label to the gridbag

nameField = new TextField(12);
constraints.gridx=0;
constraints.gridy=1;
constraints.weightx=1.0;
gridbag.setConstraints(nameField,constraints);
add(nameField);

passwordLabel = new Label(" Enter Password");
constraints.gridx=1;
constraints.gridy=0;
constraints.weightx=1.0;
gridbag.setConstraints(passwordLabel,constraints);
passwordLabel.setForeground(Color.black);
passwordLabel.setFont(new Font("Serif", Font.BOLD,18));
add( passwordLabel);

passwordField = new TextField(12);
constraints.gridx=1;
constraints.gridy=1;
constraints.weightx=1.0;
gridbag.setConstraints(passwordField,constraints);
add(passwordField);


submitButton = new Button("Submit");
constraints.gridx=2;
constraints.gridy=2;
constraints.weightx=1.0;
gridbag.setConstraints(submitButton,constraints);

submitButton.addActionListener(this);
add(submitButton);

bHelp = new Button("Help");
constraints.gridx=2;
constraints.gridy=1;
constraints.weightx=1.0;
gridbag.setConstraints(submitButton,constraints);
submitButton.addActionListener(this);
add(bHelp);


setSize(300,200); //stes the size of the display window
}


public void actionPerformed (ActionEvent e) //method to act on any actions
{
if (e.getSource() == submitButton) //if the submit button is clicked
{

nameField.setText("Thanks"); //put text in nameField just to make sure
the actionlistener is working
}

//end action performed

}
}
