JTreeFileBrowser

v1.1

JTreeFileBrowser is a java swing component for browsing a file system under a tree view. This is similar to a windows file explorer view.

This component has :
The action model (ActionModel) can be updated and the toolbar content is updated dynamically.

The main tree is a set of files and directories. The appearance can be updated with a delegate (FileView). This delegate can change the background, foreground color and the icon of a file or a directory. A drag'n drop for moving a file can be disabled calling setEnabledFileMoving, this is similar when renaming a file or a directory name by double-clicking calling setEnabledFileRenaming. The user can listen for a selection calling addFileSelectionListener.

By default the component works with one selection at a time, the setMultipleSelection method can be called for multiple selections usage.

A file filter must be added before the visibility of the component inside a FileFilterModel. This filter will update the way each file is displayed.

A main action is a java.swing.Action located at the bottom of the component. This action is provided once inside the JTreeFileBrowser constructor.
