Question

I am programmi an application for mac and I would like to have an about window to show to the user some infos, like the one of Finder.

Actually I am using this code:

System.setProperty("apple.laf.useScreenMenuBar", "true");
// SET NAME IN THE MACMENUBAR
System.setProperty("com.apple.mrj.application.apple.menu.about.name", Constants.APP_NAME);  
Application application = Application.getApplication();
Image image = Toolkit.getDefaultToolkit().getImage("res/logo.png");
application.setDockIconImage(image);
application.setAboutHandler(new AboutHandler() {
public void handleAbout(AboutEvent arg0) {

JOptionPane.showMessageDialog(null, "Some infos.");
}
});;

but the thing that I obtain is not what I want, because is a dialog box with the “logo.png” image on the left and the text on the right. And also a big awful “OK” button that you must press to close the window.

How can I make a simple about window like Finder’s ?

Can you help me? I found many tutorial on the net, but all are using deprecated methods in Application class.

(sorry for my bad english, I am italian)

You have at least two options:

1. Create a JPanel (possibly your own subclass) and layout the components in it as you want. Then show it with JOptionPane.showMessageDialog() by passing it as the first argument, rather than passing null as you have.

2. Create a JDialog and layout the components yourself. Again, you may want to create a subclass of JDialog to do this.
