All Implemented Interfaces:

ItemController<DataT,org.zkoss.zul.TreeModel<DataT>,ITree,ITreeitem>
```
public class ITreeController<DataT>
extends java.lang.Object
implements ItemController<DataT,org.zkoss.zul.TreeModel<DataT>,ITree,ITreeitem>
```
An ITree controller to control any operation on the given model.
Note: this class is not thread-safe, so when it's used in multi-threading environment, the developer should handle the threading issue.

  - setModel
```
public void setModel(org.zkoss.zul.TreeModel<DataT> model)
```
    Description copied from interface: ItemController
    Sets the given model to this controller.
    Note: calling this method after ItemController.build(), you should invoke ItemController.build() again to take effect to replace the current one at client.
    For example,
    
    uiAgent.replaceWith(locator, itemController.build());
    
    Default: null
    Specified by:
    
    setModel in interface ItemController<DataT,org.zkoss.zul.TreeModel<DataT>,ITree,ITreeitem>
  - getModel
```
public org.zkoss.zul.TreeModel<DataT> getModel()
```
    Description copied from interface: ItemController
    
    Returns the model, which is set through by ItemController.setModel(Object), or null.
    
    Specified by:
    
    getModel in interface ItemController<DataT,org.zkoss.zul.TreeModel<DataT>,ITree,ITreeitem>
  - setRenderer
```
public void setRenderer(CheckedFunction2<DataT,java.lang.Integer,ITreeitem> renderer)
```
    Description copied from interface: ItemController
    Sets the renderer which is used to render each data if ItemController.getModel() is not null.
    Note: calling this method after ItemController.build(), you should invoke ItemController.build() again to take effect to replace the current one at client.
    For example,
    
    uiAgent.replaceWith(locator, itemController.build());
    
    Default: null, or depended on the implementation
    Specified by:
    
    setRenderer in interface ItemController<DataT,org.zkoss.zul.TreeModel<DataT>,ITree,ITreeitem>
  - getRenderer
```
public CheckedFunction2<DataT,java.lang.Integer,ITreeitem> getRenderer()
```
    Description copied from interface: ItemController
