Performing a Unique Action

Although the most common use for a file chooser is to open or save files, XFileChooser allows you to select a file for any other action you specify. To this end, a "generic" method for bringing up a file chooser window, showDialog(), is provided in addition to showOpenDialog() and showSaveDialog(). (Since the file chooser itself doesn't affect files, the only difference between a custom dialog and the others is the title on the dialog window and the label on the "accept" button.)
