All Implemented Interfaces:

ChangeListener, java.util.EventListener, ImageObserver, MenuContainer

public class JSpinner

extends JPanel

implements ChangeListener

Implementation of Swing's JSpinner class. We actually use a text box and a vertical scrollbar to get the same effect with native widgets.

addFocusListener

public void addFocusListener(FocusListener l)

Description copied from class: Component

Add a KeyListener to this component

Overrides:

addFocusListener in class Component

removeFocusListener

public void removeFocusListener(FocusListener l)

Description copied from class: Component

Remove an KeyListener from the component

Overrides:

removeFocusListener in class Component

addKeyListener

public void addKeyListener(KeyListener l)

Description copied from class: Component

Add a KeyListener to this component

Overrides:

addKeyListener in class Component

processChangeEvent

public void processChangeEvent(ChangeEvent e)

setValue

public void setValue(java.lang.Object o)

getValue

public java.lang.Object getValue()

setEnabled

public void setEnabled(boolean b)

Description copied from class: Component

Change the enabled state of the component

Overrides:

setEnabled in class Component

isEnabled

public boolean isEnabled()

Description copied from class: Component

Returns true if the component is enabled

Overrides:

isEnabled in class Component

getToolTipText

public java.lang.String getToolTipText()

Description copied from class: Component

Returns the tooltip text used on the component

Overrides:

setToolTipText

public void setToolTipText(java.lang.String tip)

Description copied from class: Component

Sets the tooltip text used on the component

Overrides:

setToolTipText in class Component

previousItem

protected void previousItem()

nextItem

protected void nextItem()

requestFocus

public void requestFocus()

Description copied from class: Component

Requests the component receives the focus

Overrides:

requestFocus in class Component

grabFocus

public void grabFocus()

Description copied from class: Component

Forces keyboard focus to the component

Overrides:

grabFocus in class Component

getJTextField

public JTextField getJTextField()

stateChanged

public void stateChanged(ChangeEvent e)

Specified by:

stateChanged in interface ChangeListener

setBounds

public void setBounds(int x,
                      int y,
                      int width,
                      int height)

Component displays oddly since we used a vertical scrollbar. This should lock it to no more than 30 pixels in height when LayoutManagers try to update it

Overrides:

setBounds in class Component

calculatePreferredSize

protected Dimension calculatePreferredSize()

Overriden to calculate non-realised preferred size.

Overrides:

calculatePreferredSize in class JPanel

setSwingWTParent

                      throws java.lang.Exception

Description copied from class: JPanel

Callback for when this is added to a Container to create the peer and load cached values.

Overrides:

setSwingWTParent in class JPanel

Throws:

java.lang.Exception
