public synchronized void addNotify()

Tells this component that it has been added to a container. This is a standard Java AWT method which gets called by the AWT when this component is added to a container. Typically, it is used to create this component's peer. It has been overridden here to hook-up event listeners.

Overrides:

addNotify in class Panel

See Also:

removeNotify

public synchronized void addPropertyChangeListener(PropertyChangeListener listener)

Adds a listener for all property change events.

Parameters:

listener - the listener to add

Returns:

the current value of the calendar.

public java.awt.Color getSelectedColor()

Returns the color that highlights the selected date on the calendar.

Returns:

the current selected color.

public java.awt.Dimension minimumSize()

Returns the minimum dimensions to properly display this component. This is a standard Java AWT method which gets called to determine the minimum size of this component.

Returns:

the minimum dimensions needed for the calender (250 x 200 pixels).

Overrides:

minimumSize in class Container

See Also:

preferredSize

public void paint(Graphics g)

Paints this component using the given graphics context. This is a standard Java AWT method which typically gets called by the AWT to handle painting this component. It paints this component using the given graphics context. The graphics context clipping region is set to the bounding rectangle of this component and its <0,0> coordinate is this component's top-left corner.

Parameters:

g - the graphics context used for painting

Overrides:

paint in class Container

See Also:

repaint, update

public java.awt.Dimension preferredSize()

Returns the recommended dimensions to properly display this component. This is a standard Java AWT method which gets called to determine the recommended size of this component.

Returns:

the preferred dimensions for the calender (250 x 200 pixels).

Overrides:

preferredSize in class Container

See Also:

minimumSize

public synchronized void removeActionListener(ActionListener l)

Removes the specified action listener so it no longer receives action events from this button.

Parameters:

l - the action listener

public synchronized void removeNotify()

Tells this component that it is being removed from a container. This is a standard Java AWT method which gets called by the AWT when this component is removed from a container. Typically, it is used to destroy the peers of this component and all its subcomponents. It has been overridden here to unhook event listeners.

Overrides:

removeNotify in class Container

See Also:

addNotify

public synchronized void removePropertyChangeListener(PropertyChangeListener listener)

Removes a listener for all property change events.

Parameters:

listener - the listener to remove

See Also:

addPropertyChangeListener

public synchronized void removeVetoableChangeListener(VetoableChangeListener listener)

Removes a listener for all vetoable property change events.

Parameters:

listener - the listener to remove

addVetoableChangeListener

public void setActionCommand(String command) throws PropertyVetoException

Sets the command name of the action event fired by this button.

Parameters:

command - The name of the action event command fired by this button

Throws: PropertyVetoException

if the specified property value is unacceptable

public void setDate(String date) throws PropertyVetoException

Sets the date selected on the calendar.

Parameters:

date - the date that the calendar is to be set to

Throws: PropertyVetoException

if the specified property value is unacceptable

public void setLayout(LayoutManager lm)

Takes no action. This is a standard Java AWT method which gets called to specify which layout manager should be used to layout the components in standard containers. Since layout managers CANNOT BE USED with this container the standard setLayout has been OVERRIDDEN for this container and does nothing.

Parameters:

lm - the layout manager to use to layout this container's components (IGNORED)

Overrides:

setLayout in class Container

See Also:

getLayout

public void setSelectedColor(Color c) throws PropertyVetoException

Sets the color used to highlight the selected date on the calendar.

Parameters:

c - the color that the selected color is to be set to

Throws: PropertyVetoException

if the specified property value is unacceptable

public void sourceActionEvent()

Fire an action event to the listeners

public void update(Graphics g)

Handles redrawing of this component on the screen. This is a standard Java AWT method which gets called by the Java AWT (repaint()) to handle repainting this component on the screen. The graphics context clipping region is set to the bounding rectangle of this component and its <0,0> coordinate is this component's top-left corner. Typically this method paints the background color to clear the component's drawing space, sets graphics context to be the foreground color, and then calls paint() to draw the component. It is overridden here to reduce flicker by eliminating the uneeded clearing of the background.

Parameters:

g - the graphics context

Overrides:

update in class Container

See Also:

repaint, paint
