Constructor Detail

FileTree

public FileTree(FileRef root,
                FileSystem fs,
                boolean foldersOnly)
         throws Throwable

create a new instance of class FileTree

Parameters:

root - the root folder to create the tree with

fs - the file system this tree shows content from

foldersOnly - true, when only folders should be shown in tree (i.e., no files as leafs)

Throws:

Throwable

Method Detail

getSelectedPaths

public String[] getSelectedPaths()

get the absolute file paths of all nodes (files) that are currently selected in the tree

Returns:

a string array with absolute paths of all cuurently selected files

folderChanged

public void folderChanged(EventObject e)

listen to changes to the folder that is displayed in the file table so that the currently selected tree node (i.e. folder) can be adjusted when the user chages the folder in the file table.

Specified by:

folderChanged in interface FileTableListener

Parameters:

e - the causing event

contentChanged

public void contentChanged(FileSystemEvent event)

update tree display with created, deleted or renamed folders

Specified by:

contentChanged in interface FileSystemListener

Parameters:

event - the event object with details about the change
