public static class JSpinner.DefaultEditor
- extends JPanel
- implements ChangeListener, PropertyChangeListener, LayoutManager
A simple base class for more specialized editors that displays a read-only view of the model's current value with a JFormattedTextField. Subclasses can configure the JFormattedTextField to create an editor that's appropriate for the type of model they support and they may want to override the stateChanged and propertyChanged methods, which keep the model and the text field in sync.
This class defines a dismiss method that removes the editors ChangeListener from the JSpinner that it's part of. The setEditor method knows about DefaultEditor.dismiss, so if the developer replaces an editor that's derived from JSpinner.DefaultEditor its ChangeListener connection back to the JSpinner will be removed. However after that, it's up to the developer to manage their editor listeners. Similarly, if a subclass overrides createEditor, it's up to the subclasser to deal with their editor subsequently being replaced (with setEditor). We expect that in most cases, and in editor installed with setEditor or created by a createEditor override, will not be replaced anyway.
This class is the LayoutManager for it's single JFormattedTextField child. By default the child is just centered with the parents insets.

JSpinner.DefaultEditor
public JSpinner.DefaultEditor(JSpinner spinner)
-
Constructs an editor component for the specified JSpinner. This DefaultEditor is it's own layout manager and it is added to the spinner's ChangeListener list. The constructor creates a single JFormattedTextField child, initializes it's value to be the spinner model's current value and adds it to this DefaultEditor.
-
Parameters:
-
spinner - the spinner whose model this editor will monitor
-
See Also:
-
getTextField()
,
JSpinner.addChangeListener(javax.swing.event.ChangeListener)
dismiss
public void dismiss(JSpinner spinner)
-
Disconnect this editor from the specified JSpinner. By default, this method removes itself from the spinners ChangeListener list.
-
-
-
Parameters:
-
spinner - the JSpinner to disconnect this editor from; the same spinner as was passed to the constructor.
getSpinner
public JSpinner getSpinner()
-
Returns the JSpinner ancestor of this editor or null if none of the ancestors are a JSpinner. Typically the editor's parent is a JSpinner however subclasses of
JSpinner
may override the the createEditor method and insert one or more containers between the JSpinner and it's editor.
-
-
-
Returns:
-
JSpinner ancestor; null if none of the ancestors are a JSpinner
-
See Also:
-
JSpinner.createEditor(javax.swing.SpinnerModel)
getTextField
public JFormattedTextField getTextField()
-
Returns the JFormattedTextField child of this editor. By default the text field is the first and only child of editor.
-
-
-
Returns:
-
the JFormattedTextField that gives the user access to the SpinnerDateModel's value.
-
See Also:
-
getSpinner()
,
JSpinner.getModel()
stateChanged
public void stateChanged(ChangeEvent e)
-
This method is called when the spinner's model's state changes. It sets the value of the text field to the current value of the spinners model.
-
-
Specified by:
-
stateChanged
in interface
ChangeListener
-
-
Parameters:
-
e - the ChangeEvent whose source is the JSpinner whose model has changed.
-
See Also:
-
getTextField()
,
JSpinner.getValue()
propertyChange
public void propertyChange(PropertyChangeEvent e)
-
Called by the JFormattedTextField PropertyChangeListener. When the "value" property changes, which implies that the user has typed a new number, we set the value of the spinners model.
This class ignores PropertyChangeEvents whose source is not the JFormattedTextField, so subclasses may safely make this DefaultEditor a PropertyChangeListener on other objects.
-
-
Specified by:
-
propertyChange
in interface
PropertyChangeListener
-
-
Parameters:
-
e - the PropertyChangeEvent whose source is the JFormattedTextField created by this class.
-
See Also:
-
getTextField()
addLayoutComponent
public void addLayoutComponent(String name,
Component child)
-
This LayoutManager method does nothing. We're only managing a single child and there's no support for layout constraints.
-
-
Specified by:

addLayoutComponent
in interface
LayoutManager
-
-
Parameters:
-
name - ignored
-
child - ignored
removeLayoutComponent
public void removeLayoutComponent(Component child)
-
This LayoutManager method does nothing. There isn't any per-child state.
-
-
Specified by:
-
removeLayoutComponent
in interface
LayoutManager
-
-
Parameters:
-
child - ignored
preferredLayoutSize
public Dimension preferredLayoutSize(Container parent)
-
Returns the preferred size of first (and only) child plus the size of the parents insets.
-
-
Specified by:
-
preferredLayoutSize
in interface
LayoutManager
-
-
Parameters:
-
parent - the Container that's managing the layout
-
Returns:
-
the preferred dimensions to lay out the subcomponents of the specified container.
-
See Also:
-
LayoutManager.minimumLayoutSize(java.awt.Container)
minimumLayoutSize
public Dimension minimumLayoutSize(Container parent)
-
Returns the minimum size of first (and only) child plus the size of the parents insets.
-
-
Specified by:
-
minimumLayoutSize
in interface
LayoutManager
-
-
Parameters:
-
parent - the Container that's managing the layout
-
Returns:
-
the minimum dimensions needed to lay out the subcomponents of the specified container.
-
See Also:
-
LayoutManager.preferredLayoutSize(java.awt.Container)
layoutContainer
public void layoutContainer(Container parent)
-
Resize the one (and only) child to completely fill the area within the parents insets.
-
-
Specified by:
-
layoutContainer
in interface
LayoutManager
-
-
Parameters:
-
parent - the container to be laid out
commitEdit
public void commitEdit()
throws ParseException
-
Pushes the currently edited value to the SpinnerModel.
The default implementation invokes commitEdit on the JFormattedTextField.
-
-
-
Throws:
-
ParseException
- if the edited value is not legal
getBaseline
public int getBaseline(int width,
int height)
-
Returns the baseline.
-
-
Overrides:
-
getBaseline
in class
JComponent
-
-
Parameters:
-
width - the width to get the baseline for
-
height - the height to get the baseline for
-
Returns:
-
the baseline or < 0 indicating there is no reasonable baseline
-
Throws:
-
IllegalArgumentException
- if width or height is < 0
-
Since:
-
1.6
-
See Also:
-
JComponent.getBaseline(int,int)
,

getBaselineResizeBehavior
public Component.BaselineResizeBehavior getBaselineResizeBehavior()
-
Returns an enum indicating how the baseline of the component changes as the size changes.
-
-
Overrides:
-
getBaselineResizeBehavior
in class
JComponent
-
-
Returns:
-
an enum indicating how the baseline changes as the component size changes
-
Throws:
-
NullPointerException
