Method Detail

getRenderer

public ButtonRenderer getRenderer()

Description copied from class: AbstractRendererConnector

A subclass of AbstractRendererConnector should override this method as shown below. The framework uses GWT.create(Class) to create a renderer based on the return type of the overridden method, but only if AbstractRendererConnector.createRenderer() is not overridden as well:

 public MyRenderer getRenderer() {
     return (MyRenderer) super.getRenderer();
 }
 

Overrides:

getRenderer in class AbstractRendererConnector<String>

Returns:

the renderer bound to this connector

Specified by:

getState

public ButtonRendererState getState()

Description copied from class: AbstractConnector

Returns the shared state object for this connector. Override this method to define the shared state type for your connector.

the current shared state (never null)

public void onStateChanged(StateChangeEvent stateChangeEvent)

Description copied from interface: StateChangeEvent.StateChangeHandler
