All Implemented Interfaces:

ItemController<DataT,org.zkoss.zul.ListModel<DataT>,IChosenbox,String>

public class IChosenboxController<DataT>
extends Object
implements ItemController<DataT,org.zkoss.zul.ListModel<DataT>,IChosenbox,String>

model - The list model to associate with the chosenbox.

setModel

public void setModel(org.zkoss.zul.ListModel<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.ListModel<DataT>,IChosenbox,String>

getModel

public org.zkoss.zul.ListModel<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.ListModel<DataT>,IChosenbox,String>

setRenderer

public void setRenderer(CheckedFunction2<DataT,Integer,String> 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.ListModel<DataT>,IChosenbox,String>

getRenderer

public CheckedFunction2<DataT,Integer,String> 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.ListModel<DataT>,IChosenbox,String>

build
