protected JComponent |
createEditor()
This method is called by installUI to get the editor component of the
JSpinner . |
protected LayoutManager |
createLayout()
Create a
LayoutManager that manages the editor ,
nextButton , and previousButton children
of the JSpinner. |
protected Component |
createNextButton()
Create a component that will replace the spinner models value with the
object returned by
spinner.getNextValue . |
protected Component |
createPreviousButton()
Create a component that will replace the spinner models value with the
object returned by
spinner.getPreviousValue . |

createUI(JComponent b) |
protected void |
replaceEditor(JComponent oldEditor,

. By default
the previousButton
is a JButton who's ActionListener
updates it's JSpinner
ancestors model. If a
previousButton isn't needed (in a subclass) then override this method to
return null.createPreviousButton

protected Component createNextButton()

. By default the
nextButton
is a JButton who's ActionListener
updates it's JSpinner
ancestors model. If a nextButton
isn't needed (in a subclass) then override this method to return null.createNextButton

createPreviousButton()
protected JComponent createEditor()
JSpinner
. By default it just returns JSpinner.getEditor()
.
Subclasses can override createEditor
to return a
component that contains the spinner's editor or null, if they're going
to handle adding the editor to the JSpinner
in an installUI
override.
Typically this method would be overridden to wrap the editor with a container with a custom border, since one can't assume that the editors border can be set directly.
The replaceEditor
method is called when the spinners
editor is changed with JSpinner.setEditor
. If you've
overriden this method, then you'll probably want to override replaceEditor
as well.

protected LayoutManager createLayout()
LayoutManager
that manages the editor
,
nextButton
, and previousButton
children
of the JSpinner. These three children must be added with a constraint
that identifies their role: "Editor", "Next", and "Previous". The
default layout manager can handle the absence of any of these children.createLayout

protected void replaceEditor(JComponent oldEditor, JComponent newEditor)
PropertyChangeListener
when the JSpinner
editor property changes. It's the responsibility of this method to
remove the old editor and add the new one. By default this operation is
just:
spinner.remove(oldEditor); spinner.add(newEditor, "Editor");The implementation of
replaceEditor
should be coordinated
with the createEditor
method.replaceEditor
