AbstractTextField
public AbstractTextField()
renderComponent
protected void renderComponent(IMarkupWriter writer,
IRequestCycle cycle)
- Renders the form element, or responds when the form containing the element is submitted (by
checking
Form.isRewinding()
.
- Specified by:
renderComponent
in class AbstractComponent
beforeCloseTag
protected void beforeCloseTag(IMarkupWriter writer,
IRequestCycle cycle)
- Invoked from
AbstractComponent.render(IMarkupWriter, IRequestCycle)
just before the tag is closed.
This implementation does nothing, subclasses may override.
updateValue
protected abstract void updateValue(java.lang.String value)
- Invoked by
AbstractComponent.render(IMarkupWriter writer, IRequestCycle cycle)
when a value is
obtained from the HttpServletRequest
.
readValue
protected abstract java.lang.String readValue()
- Invoked by
AbstractComponent.render(IMarkupWriter writer, IRequestCycle cycle)
when rendering a
response.
- Returns:
- the current value for the field, as a String, or null.
isHidden
public abstract boolean isHidden()
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.
