Method Detail

setDestroy

public abstract void setDestroy(boolean destroy)

getDestroy

public abstract boolean getDestroy()

Determined dynamically at runtime during rendering, informs widget implementations if they should destroy their client side widget equivalents or leave them in tact.

Returns:

True if the widget should be destroyed on this render, false otherwise.

renderComponent

public void renderComponent(IMarkupWriter writer,
                            IRequestCycle cycle)

Invoked by AbstractComponent.render(IMarkupWriter, IRequestCycle)to actually render the component (with any parameter values already set). This is the method that subclasses must implement.
