applet in a JFrame

[jite eghagha]

Hi,

Below is my main, and my attempt to get the applet contentPane into the JFrames. But nothing shows in the JFrame. Is something wrong with my code?


public static void main(String arg[]) {
JFrame f = new JFrame();
JApplet datamartApplet = new dataMartJApplet();
datamartApplet.init();
f.setContentPane(datamartApplet.getContentPane());
f.setBounds(0,0,750,500);
f.setVisible(true);
f.setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE);
f.addWindowListener(new WindowAdapter() {
public void windowClosed(WindowEvent e) {
System.exit(0);
}
});
}

Why not just do this?

public static void main(String arg[]) {
JFrame f = new JFrame();
f.setLayout(new BorderLayout());
JApplet datamartApplet = new dataMartJApplet();
datamartApplet.init();

f.add(datamartApplet, BorderLayout.CENTER);
 
f.setVisible(true);
f.setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE);
f.addWindowListener(new WindowAdapter() {
public void windowClosed(WindowEvent e) {
System.exit(0);
}});
}

If you read up on the applet lifecycle, you'll see that its 'start' method needs to be called to begin execution.

If you want to run an applet as an application, have a look at the MainFrame class, which provides a better environment to do that.

Thank you very much, i have a follow up question.

What about a reverse situation.

I need to get a class that extends JFrame to run in an applet.

public class DataMartJFrameUI extends javax.swing.JFrame

Here's my code so far; It will load both applet and DataMartJFrameUI seperately.

public class MyApplet extends JApplet {
private DataMartJFrameUI myFrame;
public MyApplet() {
init();
}
public void init() {
DataMartJFrameUI ddf = new DataMartJFrameUI();
ddf.setVisible(true);
myFrame.setSize(500, 300);
}
}

Follow the link I posted, and read about the "ApplicationApplet" class. It does the opposite of MainFrame - allowing you to run an application as an applet.

Without package Acme; that link isn't much help.

I read through the code but don't see anything that embeds a JFrame in the applet.

The other classes of the Acme package that may be required can be downloaded from that site as well.

I read through the code but don't see anything that embeds a JFrame in the applet.

That class helps embed an application (doesn't matter whether it uses a JFrame or not) in an applet. That's what you were trying to do, no? It would be trivial to change the "Applet" (which it currently is) to a "JApplet".

If you don't have a full application -just the class extending JFrame- what's stopping you from opening that in an applet?
