Buttons in applets

[Beracosta]

Hi! I have a problem. I wanna have 2 buttons in my applet.

When u click on button 1 it should print a text in the applet.

When u click on button 2 a singel line should be painted in the applet.

I don't know how to get these buttons and how to register listeners for them. can anybody help me?

Something like this:

private JButton B1;
private JButton B2;

public void init()
{
// JApplet init with your code.

B1 = new JButton("Button 1"
B1.addActionListener(new ButtonActionListener()); // reg
B2 = new JButton("Button 2"
B2.addActionListener(new ButtonActionListener()); // reg

// more code you may want in the init.
}

// Inner Class for the Buttons.
class ButtonActionListener implements ActionListener
{
public void actionPerformed(ActionEvent ev)
{
if (ev.getSource() == B1)
{
// your code here for Button 1
}
if (ev.getSource() == B2)
{
// your code here for Button 2
}
}
}

I'll leave the text part and drawing line part to you. Hint: Use the Graphics class in your JApplet paint method.
Use the Sun API Docs which you can download for free. Consider buying a begginers Java book or take a java class.

Good luck,
Brian
