Program design

This page describes the current program design.

Architecture Design

FreeMind is a Java application that uses the Java Swing library. The basic design is based on the Model-View-Controller model.

It's central graphic components (MapView and NodeView) allow displaying of arbitrary map implementations implementing interface MindMap extending swing interface TreeModel. The implementations include currently

• MindMapMapModel used for editing of mind maps,
• BrowseMapModel used for displaying a mind map in a browser or in a so-called browse mode,
• FileMapModel used for displaying of file directory tree as a mind map.

All kinds of MindMap use MindMapNode for representing a single node.

Different modes are equipped with mode controllers implementing interface ModeController. The mode controllers are responsible for registering of Actions, Menu Items, Hot Keys and Mouse Listeners which are available for the user. The mode controller of the edit mode MindMapMode takes the required menu structure from file mindmap_menus.xml. It can also include classes registered as Plug-Ins and loaded at the run-time using reflection.

It makes possible to create a relatively small sized freemindbrowser.jar with applet viewer using a part of classes included on the whole program.

Startup

1. Freemind is started by invoking a script:

Starting Scripts

Windows	freemind.bat
Linux	freemind.sh

2. The main class invoked by the script is: freemind.main.FreeMindStarter
3. FreeMindStarter checks the Java version and then invokes Freemind.main.
4. The Freemind takes care of initialization, setting the look and feel, loads maps and makes the GUI visible.

   NOTE:It might make some sense to refactor this class, it's very large and complicated.

5. It appears that freemind.modes.ModeController takes over control at this point.

GUI Design Principles

The purpose of FreeMind is to provide an easy-to-use Mind Mapping application. It is important to make the users experience with the program as easy, natural, and intuitive as possible. The interface should be uncluttered and easy to navigate.

Need more on this from people who know more about the program.
