Speed up file searching in JFileChooser Traditionally, users choose files by scrolling the file chooser's list with their mice. You can speed that process by enhancing JFileChooser with a type-ahead method: the user just types the first few characters of a filename to select the desired file. This article shows you how to do just that. Plus, you'll learn how to register listeners on a compound component's descendants to extend JFileChooser's functionality. |
