Method Detail

createUI

public static ComponentUI createUI(JComponent b)

createPreviousButton

protected Component createPreviousButton()
Create a component that will replace the spinner models value with the object returned by spinner.getPreviousValue. 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.

Overrides:
createPreviousButton in class com.sun.java.swing.plaf.windows.WindowsSpinnerUI
Returns:
a component that will replace the spinners model with the next value in the sequence, or null
See Also:
BasicSpinnerUI.installUI(javax.swing.JComponent), createNextButton()

createNextButton

protected Component createNextButton()
Create a component that will replace the spinner models value with the object returned by spinner.getNextValue. 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.

Overrides:
createNextButton in class com.sun.java.swing.plaf.windows.WindowsSpinnerUI
Returns:
a component that will replace the spinners model with the next value in the sequence, or null
See Also:
BasicSpinnerUI.installUI(javax.swing.JComponent), createPreviousButton()

createEditor

protected JComponent createEditor()
This method is called by installUI to get the editor component of the 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.

Overrides:
createEditor in class BasicSpinnerUI
Returns:
the JSpinners editor JComponent, spinner.getEditor() by default
See Also:
BasicSpinnerUI.installUI(javax.swing.JComponent), replaceEditor(javax.swing.JComponent, javax.swing.JComponent), JSpinner.getEditor()

createLayout

protected LayoutManager createLayout()
Create a 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.

Overrides:
createLayout in class BasicSpinnerUI
Returns:
a LayoutManager for the editor, next button, and previous button.
See Also:
createNextButton(), createPreviousButton(), createEditor()

replaceEditor

protected void replaceEditor(JComponent oldEditor,
                             JComponent newEditor)
Called by the 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.

Overrides:
replaceEditor in class BasicSpinnerUI
See Also:
createEditor(), BasicSpinnerUI.createPropertyChangeListener()
