- All Implemented Interfaces:
- IComponent, IFormComponent, IRender, org.apache.hivemind.Locatable, org.apache.hivemind.LocationHolder, ValidatableField
- public abstract class Select
- extends AbstractFormComponent
- implements ValidatableField
Implements a component that manages an HTML <select> form element. The most common
situation, using a <select> to set a specific property of some object, is best handled
using a PropertySelection
component. [ Component Reference ]
Otherwise, this component is very similar to RadioGroup
.
As of 4.0, this component can be validated.

prepareForRender
protected void prepareForRender(IRequestCycle cycle)
- Description copied from class:
AbstractComponent
- Invoked by
AbstractComponent.render(IMarkupWriter, IRequestCycle)
to prepare the component to render.
This implementation sets JavaBeans properties from matching bound parameters. This
implementation does nothing.
- Overrides:
prepareForRender
in class AbstractComponent
- See Also:
AbstractComponent.prepareForRender(org.apache.tapestry.IRequestCycle)
cleanupAfterRender
protected void cleanupAfterRender(IRequestCycle cycle)
- Description copied from class:
AbstractComponent
- Invoked by
AbstractComponent.render(IMarkupWriter, IRequestCycle)
after the component renders. This
implementation does nothing.
- Overrides:
cleanupAfterRender
in class AbstractComponent
- See Also:
AbstractComponent.cleanupAfterRender(org.apache.tapestry.IRequestCycle)
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:

in class AbstractFormComponent
- See Also:

getValidatableFieldSupport
public abstract ValidatableFieldSupport getValidatableFieldSupport()
- Injected.
isRequired
public boolean isRequired()
- Description copied from interface:
IFormComponent
- Returns true if the field is required. This will (typically) involve consulting the
component's validators.
- Specified by:
isRequired
in interface IFormComponent
- Overrides:
isRequired
in class AbstractFormComponent
- See Also:
AbstractFormComponent.isRequired()
