Direct Known Subclasses:

CalendarPseudoWidget

public class DateWidget

extends TimeStampWidget

implements NodeGenerator

A composite widget set up to handle dates. Shows a typein box for day, drop-down for month, typein box for year, and (if JavaScript available) a button which pops up a little calendar view from which you can select the date by browsing. Date handling in Java is bizarrely awkward and obscure...

Method Detail

generateInnerHTML

public Node generateInnerHTML(Document doc,
                              Context context)
                       throws GenerationException

Generate a node representing the XHTML 1.0 representation of just this widget, without prompt, helptext or any accompanying guff, but including JavaScript support if necessary (in which case the element returned will be a span). Essentially this method is the Jacquard 2 replacement for Widget.layout(), q.v. When specialising you almost certainly want to specialise this and not generateHTML, q.v.

Overrides:

generateInnerHTML in class Widget

Parameters:

doc - the document whithin which I am to be created

context - the context in which I am to be created.

Returns:

an element representing either the INPUT element itself or a SPAN element containing the INPUT element and any other functionally supporting stuff (SCRIPTs, other INPUTs, APPLETs etc

Throws:

GenerationException

layout(uk.co.weft.dbutil.Context, int), Widget.generateHTML(org.w3c.dom.Document, uk.co.weft.dbutil.Context)

getTabPlaces

public int getTabPlaces(Context context)

Specialisation: I'm on the date part

Overrides:

getTabPlaces in class TimeStampWidget

Parameters:

context - the service context

Returns:

the number of tab places I occupy

See Also:

TimeStampWidget.getTabPlaces(uk.co.weft.dbutil.Context)

getWidth

public int getWidth(Context context)

Specialisation: I'm only the date part

Overrides:

getWidth in class TimeStampWidget

Parameters:

context - the service context

Returns:

my desired width in characters

See Also:

layout

public void layout(Context context,
                   int tabIndex)
            throws java.io.IOException,

Specialisation: I'm only the date part

Overrides:

layout in class TimeStampWidget

Parameters:

context - the service context
