JExplorerTree

Component for file management, with basic operations and DnD support

Features

It was designed to be used in the context of a specific project directory (Workspace). It is not designed to browse the file system entirely.

• Lazy load (only when it expands)
• No extra dependencies (extends JPanel and use a JTree)
• External Drag and Drop (from and to OS)
• Internal Drag and Drop (inside tree)
• Keyboard Support: F2, DELETE, ENTER
• CTRL+C, CTRL+V, CTRL+X (internal)
• CTRL+V (from external Files)
• CTRL+C (allow copy form JTree to external)
• React at external changes (grayout)
• Native Icons Support
• Basic operations
  • New File
  • New Directory
  • Rename
  • Refresh (sync external changes.)
  • Multi-File Copy / Delete
  • Copy / Move Directory (see #1)
  • Delete (with UNDO)

Methods to overwrite

• JExplorerPanel.log(String) - plug your log system
• JExplorerPanel.tr(String) - translate messages.
• JExplorerPanel.showExeption | showXXX - handle user messages.
• JExplorerPanel.handleOpenFile - called by DOUBLE-CLICK and ENTER
• JExplorerPanel.handleXXXXX - user operations.
• JExplorerPanel.configureTree - configure what you think is necessary.
• JExplorerPanel.configureMenu - configure what you think is necessary

Usage

JExplorerPanel fileExplorerPanel = new JExplorerPanel(new File(root));
jframe.add(fileExplorerPanel, BorderLayout.CENTER);

See: example

Customize menus (override initMenus):

  @Override
  protected void initMenus() {
    super.initMenus();
    popup.remove(0); // remove frist menu Add File
  }

TODO / Tests

Waiting for contributions to complement these features. ;)

• Redo (after UNDO)
• New File / Dir, has no UNDO (very easy to implement)
• Detect external changes e update root (only if another operation forces the reload)
• Test real use-case translation.
• Subdirectory
• Move with files
• Move with subfolders #1
• Copy with files
• Copy with subfolders #1
• Copy/Move, file already exists in target dir (show message) (done.. OVERRIDE BY DEFAULT)
• Undo
• UNDO with files
• UNDO directory with files
• UNDO directory with subfolders
• UNDO (/tmp folder in another partition)
• Undo / Delete - Files from diferent paths #2

Undo

The undo operation is limited to 5 actions, as it is difficult to maintain consistency .. needing further tests to fully validate.

Undo DELETE

Basically the delete operation creates a temporary folder, and moves the deleted files there.

PS: Lack of testing on MacOS and Windows 10
