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

isDisabled

public abstract 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.


setFile

public abstract void setFile(IUploadFile file)
