All Implemented Interfaces:

Buffered, BufferedValidatable, Property, Property.Editor, Property.ReadOnlyStatusChangeNotifier, Property.ValueChangeListener, Property.ValueChangeNotifier, Property.Viewer, Validatable, MethodEventSource, Paintable, Sizeable, VariableOwner, Component, Component.Focusable, Field, EventListener

Direct Known Subclasses:

InlineDateField, PopupDateField

public class DateField
extends AbstractField

A date editor component that can be bound to any bindable Property. that is compatible with java.util.Date.

Since DateField extends AbstractField it implements the Bufferedinterface. A DateField is in write-through mode by default, so AbstractField.setWriteThrough(boolean)must be called to enable buffering.

Since:

3.0

5.2.12

Constructor Detail

DateField

public DateField()

Constructs an empty DateField with no caption.

DateField

public DateField(String caption)

Constructs an empty DateField with caption.

Parameters:

caption - the caption of the datefield.

DateField

public DateField(String caption,
                 Property dataSource)

Constructs a new DateField that's bound to the specified Property and has the given caption String.

Parameters:

caption - the caption String for the editor.

dataSource - the Property to be edited with this editor.

DateField

public DateField(Property dataSource)
          throws IllegalArgumentException

Constructs a new DateField that's bound to the specified Property and has no caption.

Parameters:

dataSource - the Property to be edited with this editor.

Throws:

IllegalArgumentException

DateField

public DateField(String caption,
                 Date value)

Constructs a new DateField with the given caption and initial text contents. The editor constructed this way will not be bound to a Property unless Property.Viewer.setPropertyDataSource(Property) is called to bind it.

Parameters:

caption - the caption String for the editor.

value - the Date value.

Method Detail

paintContent

public void paintContent(PaintTarget target)
                  throws PaintException

Description copied from class: AbstractComponent

Paints any needed component-specific things to the given UIDL stream. The more general AbstractComponent.paint(PaintTarget) method handles all general attributes common to all components, and it calls this method to paint any component-specific attributes to the UIDL stream.

Overrides:

paintContent in class AbstractField

Parameters:

target - the target UIDL stream where the component should paint itself to

Throws:

PaintException - if the paint operation failed.

getTag

public String getTag()

Description copied from class: AbstractComponent

Gets the UIDL tag corresponding to the component.

Specified by:

getTag in class AbstractComponent

Returns:

the component's UIDL tag as String

changeVariables

public void changeVariables(Object source,
                            Map variables)

Description copied from interface: VariableOwner

Called when one or more variables handled by the implementing class are changed.

Specified by:

changeVariables in interface VariableOwner

Overrides:

changeVariables in class AbstractField

Parameters:

source - the Source of the variable change. This is the origin of the event. For example in Web Adapter this is the request.

variables - the Mapping from variable names to new variable values.

getType

public Class getType()

Description copied from interface: Property

Returns the type of the Property. The methods getValue and setValue must be compatible with this type: one must be able to safely cast the value returned from getValue to the given type and pass any variable assignable to this type as an argument to setValue.

Specified by:

getType in interface Property

Specified by:

getType in class AbstractField

Returns:

type of the Property

toString

public String toString()

Description copied from class: AbstractField

Returns the value of the Property in human readable textual format.

Specified by:

toString in interface Property

Overrides:

toString in class AbstractField

Returns:

String representation of the value stored in the Property

See Also:

Object.toString()

setValue

public void setValue(Object newValue)
              throws Property.ReadOnlyException,
                     Property.ConversionException

Description copied from class: AbstractField

Sets the value of the field.

Specified by:

setValue in interface Property

Overrides:

setValue in class AbstractField

Parameters:

newValue - the New value of the field.

Throws:

Property.ReadOnlyException - if the object is in read-only mode

Property.ConversionException - if newValue can't be converted into the Property's native type directly or through String

setValue

public void setValue(Object newValue,
                     boolean repaintIsNotNeeded)
              throws Property.ReadOnlyException,
                     Property.ConversionException

Description copied from class: AbstractField

Sets the value of the field.

Overrides:

setValue in class AbstractField

Parameters:

newValue - the New value of the field.

repaintIsNotNeeded - True iff caller is sure that repaint is not needed.

Throws:

Property.ReadOnlyException

Property.ConversionException

setPropertyDataSource

public void setPropertyDataSource(Property newDataSource)

Sets the DateField datasource. Datasource type must assignable to Date.

Specified by:

setPropertyDataSource in interface Property.Viewer

Overrides:

setPropertyDataSource in class AbstractField

Parameters:

newDataSource - the new data source Property.

See Also:

Property.Viewer.setPropertyDataSource(Property)

getResolution

public int getResolution()

Gets the resolution.

Returns:

int

setResolution

public void setResolution(int resolution)

Sets the resolution of the DateField.

Parameters:

resolution - the resolution to set.

setDateFormat

public void setDateFormat(String dateFormat)

Sets formatting used by some component implementations. See SimpleDateFormat for format details. By default it is encouraged to used default formatting defined by Locale, but due some JVM bugs it is sometimes necessary to use this method to override formatting. See Toolkit issue #2200.

Parameters:

dateFormat - the dateFormat to set

See Also:

com.itmill.toolkit.ui.AbstractComponent#setLocale(Locale))

getDateFormat

public String getDateFormat()

Reterns a format string used to format date value on client side or null if default formatting from Component.getLocale() is used.

Returns:

the dateFormat
