getValue

public abstract Date getValue()

setValue

public abstract void setValue(Date value)

isDisabled

public abstract boolean isDisabled()

Description copied from interface: IFormComponent

Specified by:

isDisabled in interface IFormComponent

getIncludeWeek

public abstract boolean getIncludeWeek()

getIcon

public abstract IAsset getIcon()

getImageClass

public abstract String getImageClass()

getTitle

public abstract String getTitle()

Since:

renderFormComponent

protected void renderFormComponent(IMarkupWriter writer,
                                   IRequestCycle cycle)

Description copied from class: AbstractFormComponent

Invoked from AbstractFormComponent.renderComponent(IMarkupWriter, IRequestCycle) to render the component.

Specified by:

renderFormComponent in class AbstractFormComponent

See Also:

AbstractFormComponent.renderFormComponent(org.apache.tapestry.IMarkupWriter, org.apache.tapestry.IRequestCycle)

rewindFormComponent

protected void rewindFormComponent(IMarkupWriter writer,
                                   IRequestCycle cycle)

Description copied from class: AbstractFormComponent

Invoked from AbstractFormComponent.renderComponent(IMarkupWriter, IRequestCycle) to rewind the component. If the component is disabled this will not be invoked.

Specified by:

rewindFormComponent in class AbstractFormComponent

See Also:

AbstractFormComponent.rewindFormComponent(org.apache.tapestry.IMarkupWriter, org.apache.tapestry.IRequestCycle)

getValidatableFieldSupport

public abstract ValidatableFieldSupport getValidatableFieldSupport()

Injected.

getTranslatedFieldSupport

public abstract TranslatedFieldSupport getTranslatedFieldSupport()

Injected.

isRequired

public boolean isRequired()

Description copied from class: AbstractFormComponent

Returns false. Subclasses that might be required must override this method. Typically, this involves checking against the component's validators.

Specified by:
