Class FileDialog

java.lang.Object

  +--corina.gui.FileDialog

public class FileDialog

extends Object

A convenient wrapper for JFileChooser, for typical XCorina usage.

Here's what they provide, and why you'd want to use this class over JFileChooser directly:

• automatically uses a bunch of default filters
• gets its initial directory from corina.dir.data; subsequent calls start from the last-used-directory
• incredibly neat preview component
• multiple-file-chooser lets the user select several files from one dialog
• simple return values: null, or a String, or a List of Strings. No need to mess with JFileChooser.APPROVE_OPTION
