Method Detail
-
createUI
public static ComponentUI createUI(JComponent c)
Creates a new UI object for the given component.- Parameters:
c- component to create UI object for- Returns:
- the UI object
-
installDefaults
protected void installDefaults(AbstractButton b)
- Overrides:
installDefaultsin classBasicButtonUI
-
installListeners
protected void installListeners(AbstractButton b)
- Overrides:
installListenersin classBasicButtonUI
-
uninstallListeners
protected void uninstallListeners(AbstractButton b)
- Overrides:
uninstallListenersin classBasicButtonUI
-
uninstallDefaults
protected void uninstallDefaults(AbstractButton b)
- Overrides:
uninstallDefaultsin classBasicButtonUI
-
getContext
public SynthContext getContext(JComponent c)
Description copied from interface:SynthUIReturns the Context for the specified component.- Specified by:
getContextin interfaceSynthUI- Parameters:
c- Component requesting SynthContext.- Returns:
- SynthContext describing component.
-
getBaseline
public int getBaseline(JComponent c, int width, int height)
Description copied from class:BasicButtonUIReturns the baseline.- Overrides:
getBaselinein classBasicButtonUI- Parameters:
c-JComponentbaseline is being requested forwidth- the width to get the baseline forheight- the height to get the baseline for- Returns:
- baseline or a value < 0 indicating there is no reasonable baseline
- See Also:
JComponent.getBaseline(int, int)
-
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 thepaint(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
paintmethod.- Overrides:
updatein classComponentUI- Parameters:
g- theGraphicsobject used for paintingc- 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:
paintin classBasicButtonUI- Parameters:
g- theGraphicsobject used for paintingc- the component being painted- See Also:
paint(SynthContext,Graphics)
-
paint
protected void paint(SynthContext context, Graphics g)
Paints the specified component.- Parameters:
context- context for the component being paintedg- theGraphicsobject used for painting- See Also:
update(Graphics,JComponent)
-
paintBorder
public void paintBorder(SynthContext context, Graphics g, int x, int y, int w, int h)
Description copied from interface:SynthUIPaints the border.- Specified by:
paintBorderin interfaceSynthUI- Parameters:
context- a component contextg-Graphicsto paint onx- the X coordinatey- the Y coordinatew- width of the borderh- height of the border
-
getDefaultIcon
protected Icon getDefaultIcon(AbstractButton b)
Returns the default icon. This should not callback to the JComponent.- Parameters:
b- button the icon is associated with- Returns:
- default icon
-
getIcon
protected Icon getIcon(AbstractButton b)
Returns the Icon to use for painting the button. The icon is chosen with respect to the current state of the button.- Parameters:
b- button the icon is associated with- Returns:
- an icon
-
getMinimumSize
public Dimension getMinimumSize(JComponent c)
Description copied from class:ComponentUIReturns the specified component's minimum size appropriate for the look and feel. Ifnullis returned, the minimum size will be calculated by the component's layout manager instead (this is the preferred approach for any component with a specific layout manager installed). The default implementation of this method invokesgetPreferredSizeand returns that value.- Overrides:
getMinimumSizein classBasicButtonUI- Parameters:
c- the component whose minimum size is being queried; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components- Returns:
- a
Dimensionobject ornull - See Also:
JComponent.getMinimumSize(),LayoutManager.minimumLayoutSize(java.awt.Container),ComponentUI.getPreferredSize(javax.swing.JComponent)
-
getPreferredSize
public Dimension getPreferredSize(JComponent c)
Description copied from class:ComponentUIReturns the specified component's preferred size appropriate for the look and feel. Ifnullis returned, the preferred size will be calculated by the component's layout manager instead (this is the preferred approach for any component with a specific layout manager installed). The default implementation of this method returnsnull.- Overrides:
getPreferredSizein classBasicButtonUI- Parameters:
c- the component whose preferred size is being queried; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components- See Also:
JComponent.getPreferredSize(),LayoutManager.preferredLayoutSize(java.awt.Container)
-
getMaximumSize
public Dimension getMaximumSize(JComponent c)
Description copied from class:ComponentUIReturns the specified component's maximum size appropriate for the look and feel. Ifnullis returned, the maximum size will be calculated by the component's layout manager instead (this is the preferred approach for any component with a specific layout manager installed). The default implementation of this method invokesgetPreferredSizeand returns that value.- Overrides:
getMaximumSizein classBasicButtonUI- Parameters:
c- the component whose maximum size is being queried; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components- Returns:
- a
Dimensionobject ornull - See Also:
JComponent.getMaximumSize(),LayoutManager2.maximumLayoutSize(java.awt.Container)
-
getSizingIcon
protected Icon getSizingIcon(AbstractButton b)
Returns the Icon used in calculating the preferred/minimum/maximum size.
-
propertyChange
public void propertyChange(PropertyChangeEvent e)
Description copied from interface:PropertyChangeListenerThis method gets called when a bound property is changed.- Specified by:
propertyChangein interfacePropertyChangeListener- Parameters:
e- A PropertyChangeEvent object describing the event source and the property that has changed.
