Steps to render a file tree table inside a given div in a html shown as below. A combination of Orion/Client API are used in the section.

Register services

1. Define a DIV with id in the html where the tree table wil be rendered.
2. In the html loading js file , create the Service Registry.
3. Register the FileService in the registry.
4. Register the CommandService in the registry.
5. Create Command and add commands to CommandService.

var registry = new eclipse.Registry(); 
registry.registerLocalService("IFileService", "FileService", new eclipse.FileService());
var commandService = new eclipse.CommandService(registry);
registry.registerLocalService("ICommandService", "CommandService", commandService);
var favoriteCommand = new eclipse.Command();
commandService.addCommand(favoriteCommand, "object");

Model Creation

1. Create an instance of the model class to provide the tree model , the model has to implement the following functions required by TableTree.
   • getRoot(onItem).
   • getChildren(parentItem, onComplete) . It uses the FileService.getChildren to provide childen items.
   • getId(item)

Renderer Creation

1. Create an instance of the renderer class to render table rows (refer to Table Tree)
   • Implement check box rendering
   • Implement table-row based actions
   • Implement folder toggles by calling Table Tree's other API(TODO: Define other APIs)

TableTree Creation

1. Create an instance of Table Tree
2. In the onLoad of the html , use a wrapper class instance to wrap the Table Tree and initialize the table.
