Method Detail

getValue

public abstract java.util.Date getValue()

setValue

public abstract void setValue(java.util.Date value)

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.

Specified by:
isDisabled in interface IFormComponent

getIncludeWeek

public abstract boolean getIncludeWeek()

getIcon

public abstract IAsset getIcon()

getScript

public abstract IScript getScript()
Injected

Since:
4.0

renderFormComponent

protected void renderFormComponent(IMarkupWriter writer,
                                   IRequestCycle cycle)
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)
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:
isRequired in interface IFormComponent
Overrides:
isRequired in class AbstractFormComponent

AbstractFormComponent.isRequired()
