Constructor Detail

SynthSpinnerUI

public SynthSpinnerUI()

Method Detail

createUI

public static ComponentUI createUI(JComponent c)

Returns a new instance of SynthSpinnerUI.

Parameters:: c - the JSpinner (not used)
Returns:: a new SynthSpinnerUI object
See Also:: ComponentUI.createUI(javax.swing.JComponent)

installDefaults

protected void installDefaults()

Initializes the JSpinner border, foreground, and background, properties based on the corresponding "Spinner.*" properties from defaults table. The JSpinners layout is set to the value returned by createLayout. This method is called by installUI.

Overrides:: installDefaults in class BasicSpinnerUI
See Also:: uninstallDefaults(), BasicSpinnerUI.installUI(javax.swing.JComponent), BasicSpinnerUI.createLayout(), LookAndFeel.installBorder(javax.swing.JComponent, java.lang.String), LookAndFeel.installColors(javax.swing.JComponent, java.lang.String, java.lang.String)

uninstallDefaults

protected void uninstallDefaults()

Sets the JSpinner's layout manager to null. This method is called by uninstallUI.

Overrides:: uninstallDefaults in class BasicSpinnerUI
See Also:: installDefaults(), BasicSpinnerUI.uninstallUI(javax.swing.JComponent)

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()

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
Parameters:: oldEditor - an old instance of editor; newEditor - a new instance of editor
See Also:: createEditor(), BasicSpinnerUI.createPropertyChangeListener()

update

public void update(Graphics g,
                   JComponent c)

Notifies this UI delegate to repaint the specified component. This method paints the component background, then calls the paint(SynthContext,Graphics) method.

In general, this method does not need to be overridden by subclasses. All Look and Feel rendering code should reside in the paint method.

Overrides:: update in class ComponentUI
Parameters:: g - the Graphics object used for painting; c - the component being painted
See Also:: paint(SynthContext,Graphics)

paint

public void paint(Graphics g,
                  JComponent c)

Paints the specified component according to the Look and Feel.

This method is not used by Synth Look and Feel. Painting is handled by the paint(SynthContext,Graphics) method.

Overrides:: paint in class ComponentUI
Parameters:: g - the Graphics object used for painting; c - the component being painted
See Also:: paint(SynthContext,Graphics)

paint

protected void paint(SynthContext context,
                     Graphics g)

Paints the specified component. This implementation does nothing.

Parameters:: context - context for the component being painted; g - the Graphics object used for painting
See Also:: update(Graphics,JComponent)
