Constructor Detail

Form
public Form(FormDefinition definition)(Code)

Method Detail

addProcessingPhaseListener
public void addProcessingPhaseListener(ProcessingPhaseListener listener)(Code)

addWidgetEvent
public void addWidgetEvent(WidgetEvent event)(Code)
	Events produced by child widgets should not be fired immediately, but queued in order to ensure an overall consistency of the widget tree before being handled. Parameters: event - the event to queue

doValidate
public boolean doValidate(FormContext formContext)(Code)

endProcessing
public void endProcessing(boolean redisplayForm)(Code)
	End the current form processing after the current phase. Parameters: redisplayForm - indicates if the form should be redisplayed to the user.

generateLabel
public void generateLabel(ContentHandler contentHandler) throws SAXException(Code)

generateSaxFragment
public void generateSaxFragment(ContentHandler contentHandler, Locale locale) throws SAXException(Code)

getAttribute
public Object getAttribute(String name)(Code)

getLocale
public Locale getLocale()(Code)
	Get the locale to be used to process this form. the form's locale.

getSubmitWidget
public Widget getSubmitWidget()(Code)
	Get the widget that triggered the current processing. Note that it can be any widget, and not necessarily an action or a submit. the widget that submitted this form.

isValid
public boolean isValid()(Code)
	Was form validation successful ? `true` if the form was successfully validated.

process

public boolean process(FormContext formContext)(Code)

Processes a form submit. If the form is finished, i.e. the form should not be redisplayed to the user, then this method returns true, otherwise it returns false. To know if the form was sucessfully validated, use the Form.isValid() method.

Form processing consists in multiple steps:

all widgets read their value from the request (i.e. Form.readFromRequest(FormContext) is called recursively on the whole widget tree)
if there is an action event, call the FormHandler
perform validation.

This processing can be interrupted by the widgets (or their event listeners) by calling Form.endProcessing(boolean) .

readFromRequest
public void readFromRequest(FormContext formContext)(Code)

removeAttribute
public void removeAttribute(String name)(Code)

removeProcessingPhaseListener
public void removeProcessingPhaseListener(ProcessingPhaseListener listener)(Code)

setAttribute
public void setAttribute(String name, Object value)(Code)

setFormHandler
public void setFormHandler(FormHandler formHandler)(Code)

setSubmitWidget
public void setSubmitWidget(Widget widget)(Code)
	Set the widget that triggered the current form processing. Parameters: widget - the widget

validate
public boolean validate(FormContext formContext)(Code)
