Constructor Details

DefaultEditor

public DefaultEditor(JSpinner spinner)
Creates a new DefaultEditor object. The editor is registered with the spinner as a ChangeListener here.
Parameters:
spinner - the JSpinner associated with this editor

Method Details

addLayoutComponent

public void addLayoutComponent(String name,
                               Component child)
This method does nothing. It is required by the LayoutManager interface, but since this component has a single child, there is no need to use this method.
Specified by:
addLayoutComponent in interface LayoutManager
Parameters:
name - the name.
child - the child component to add.

commitEdit

public void commitEdit()
            throws ParseException
DOCUMENT ME!

dismiss

public void dismiss(JSpinner spinner)
Removes the editor from the ChangeListener list maintained by the specified spinner.
Parameters:
spinner - the spinner (null not permitted).

getSpinner

public JSpinner getSpinner()
Returns the JSpinner component that the editor is assigned to.
Returns:
The spinner that the editor is assigned to.

getTextField

public JFormattedTextField getTextField()
Returns the text field used to display and edit the current value in the spinner.
Returns:
The text field.

layoutContainer

public void layoutContainer(Container parent)
Sets the bounds for the child components in this container. In this case, the text field is the only component to be laid out.
Specified by:
layoutContainer in interface LayoutManager
Parameters:
parent - the parent container.

minimumLayoutSize

public Dimension minimumLayoutSize(Container parent)
Calculates the minimum size for this component. In this case, the text field is the only subcomponent, so the return value is the minimum size of the text field plus the insets of this component.
Specified by:
minimumLayoutSize in interface LayoutManager
Parameters:
parent - the parent container.
Returns:
The minimum size.

preferredLayoutSize

public Dimension preferredLayoutSize(Container parent)
Calculates the preferred size for this component. In this case, the text field is the only subcomponent, so the return value is the preferred size of the text field plus the insets of this component.
Specified by:
preferredLayoutSize in interface LayoutManager
Parameters:
parent - the parent container.
Returns:
The preferred size.

propertyChange

public void propertyChange(PropertyChangeEvent event)
Receives notification of property changes. If the text field's 'value' property changes, the spinner's model is updated accordingly.
Specified by:
propertyChange in interface PropertyChangeListener
Parameters:
event - the event.

removeLayoutComponent

public void removeLayoutComponent(Component child)
This method does nothing. It is required by the LayoutManager interface, but since this component has a single child, there is no need to use this method.
Specified by:
removeLayoutComponent in interface LayoutManager
Parameters:
child - the child component to remove.

stateChanged

public void stateChanged(ChangeEvent event)
Receives notification of changes in the state of the JSpinner that the editor belongs to - the content of the text field is updated accordingly.
Specified by:
stateChanged in interface ChangeListener
Parameters:
event - the change event.
