Class ITreeController<DataT>

java.lang.Object

org.zkoss.stateless.state.ITreeController<DataT>

All Implemented Interfaces:

ItemController<DataT,org.zkoss.zul.TreeModel<DataT>,ITree,ITreeitem>

public class ITreeController<DataT>
extends 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.

owner - The controller to control with

model - The tree model to associate with the tree.

of

public static <D> ITreeController<D> of(ITree owner,
 org.zkoss.zul.TreeModel<D> model,
 CheckedFunction2<D,Integer,ITreeitem> renderer)

Returns the controller instance with the given tree

Parameters:

model - The tree model to associate with the tree.

renderer - The renderer of the tree model.

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,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,Integer,ITreeitem> getRenderer()

Description copied from interface: ItemController

Returns the renderer, which is set through by ItemController.setRenderer(CheckedFunction2), or a default one which is depended on implementation.

Specified by:

getRenderer in interface ItemController<DataT,org.zkoss.zul.TreeModel<DataT>,ITree,ITreeitem>

build

public ITree build()

Description copied from interface: ItemController

Returns the immutable instance that the controller to build with

Specified by:

build in interface ItemController<DataT,org.zkoss.zul.TreeModel<DataT>,ITree,ITreeitem>

getSelectedObject

public DataT getSelectedObject()

Returns the selected object.

setSelectedObject

public void setSelectedObject(DataT item)

Deselects selected object and selects the given object.

clear

public void clear()

Description copied from interface: ItemController

Clears all the rendered data.

Specified by:
