open text document using JButton

[coopc]

Hi Im trying to make an action for a JButton to open. I realise you would need to use JFileChooser and use chooser.getSelectedFile but how can I instruct it to open the file in to a separate window?

		JFileChooser chooser = new JFileChooser("C:/OOP"); 
		status=chooser.showOpenDialog(null);
		if (status == JFileChooser.APPROVE_OPTION) 
		{
			chooser.getSelectedFile();...
                 }

I don't understand what you mean by instruct it to open the file into a separate window? Perhaps you mean once the file is loaded you want it displayed in a separate frame?

You can display in another window by creating a new JFrame or a new JDialog, whichever you choose, and then adding the text from the file to that frame before you set it visible.

As for the JButton, add an action listener to the JButton like this:

javax.swing.JButton myButton = new javax.swing.JButton("Button text");
myButton.addActionListener(new java.awt.event.ActionListener() {
    public void actionPerformed(java.awt.event.ActionEvent evt) {
        myButtonAction(evt);
    }
});
 
private void myButtonAction(java.awt.event.ActionEvent evt) {
    JFileChooser...
    ...
}

I meant open it as you would if you were to go My Documents and click on the text file. Do you think that is possible?

Ah then you would use java.awt.Desktop:

if(Desktop.isDesktopSupported()) {
    Desktop desktop = Desktop.getDesktop();
    desktop.open(file);
}
