A JWindow<\/code> is a container that can be displayed anywhere on the user’s desktop. It does not have the title bar, window-management buttons, or other trimmings associated with a JFrame<\/code>, but it is still a “first-class citizen” of the user’s desktop, and can exist anywhere on it.<\/p>\n

1. Introduction<\/h2>\n

The JWindow<\/code> component contains a JRootPane<\/code> as its only child. The contentPane<\/code> should be the parent of any children of the JWindow<\/code>. As a convenience add and its variants, remove and setLayout<\/code> have been overridden to forward to the contentPane as necessary. This means you can write:<\/p>\n

JwindowExample.java<\/em><\/span><\/p>\n

window.add(child);\r\n<\/pre>\n
And the child will be added to the contentPane. The contentPane will always be non-null. Attempting to set it to null will cause the JWindow to throw an exception. The default contentPane will have a BorderLayout manager set on it.<\/p>\n
Like a JFrame<\/code>, a JWindow<\/code> is another top-level container. It is as an undecorated JFrame<\/code>. It does not have features like a title bar, windows menu, etc. It is not a very commonly used top-level container. You can use it as a splash window that displays once when the application is launched and then automatically disappears after a few seconds.<\/p>\n

Popular Java Editors:<\/b>
\nTo write your java programs you will need a text editor. There are even more sophisticated IDE available in the market. But for now, you can consider one of the following:<\/p>\n
