Question

I want to create a customised title bar for my JFrame. I can remove the default title bar with

JFrame.setUndecorated(true)

Now i need to create a customised title bar for my JFrame with a close button?

Answer 1

Without having done that ever, I think I would go this way:

1. Indeed set the JFrame to undecorated
2. Extend JRootPane to add an additional field titleBar
3. Create a TitleBar component holding the title, the close button, etc…
4. Set a new LayoutManager on that JRootPane (have a look at JRootPane.RootLayout) and layout the components in the appropriate order (first the title bar, then below the menubar, then below the content pane)
5. Set an instance of that extends RootPane on your JFrame

There are maybe better ways.
