Package thinletcommons

Class FileChooser

java.lang.Object

thinletcommons.FileChooser

public class FileChooser
extends Object

A Thinlet file chooser dialog.

The dialog is modal and blocks the calling frame/dialog. It is therefore displayed in a separate window.

TODO:

• For mode OPEN: multiple selection
• Button "Create directory"

Implementation note: This implementation uses javax.swing.filechooser.FileSystemView, because it provides directory information that looks more "native". This introduces a dependency on Swing, but since ThinG requires JDK 1.4, Swing should be there anyway. Only a minimal set of Swing classes is loaded while using javax.swing.filechooser.FileSystemView; alas, the loading of javax.swing.UIManager and javax.swing.LookAndFeel can not be avoided, although no Swing beans are actually used.

To restore the "All files" filter and remove all custom filter, call this method with argument null.
