Method Detail

renderComponent

protected void renderComponent(IMarkupWriter writer,
                               IRequestCycle cycle)

Description copied from class: AbstractComponent

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.

Specified by:

renderComponent in class AbstractComponent

getElement

public abstract String getElement()

getListener

public abstract IActionListener getListener()

Since:

2.2

getSourceBinding

public abstract IBinding getSourceBinding()

Since:

3.0

getValueBinding

public abstract IBinding getValueBinding()

getIndexBinding

public abstract IBinding getIndexBinding()

isDisabled

public boolean isDisabled()

Description copied from interface: IFormComponent

Returns true if the component is disabled. This is important when the containing form is submitted, since disabled parameters do not update their bindings.

Since:

3.0
