method:update(java.awt.Graphics,javax.swing.JComponent) [NONE]

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)

method:paint(java.awt.Graphics,javax.swing.JComponent) [NONE]

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 BasicButtonUI

Parameters:

g - the Graphics object used for painting

c - the component being painted

See Also:

paint(SynthContext,Graphics)

method:paint(javax.swing.plaf.synth.SynthContext,java.awt.Graphics) [NONE]

paint
```
protected void paint(SynthContext context,
                     Graphics g)
```
Paints the specified component.

Parameters:

context - context for the component being painted

g - the Graphics object used for painting

See Also:

update(Graphics,JComponent)

method:paintBorder(javax.swing.plaf.synth.SynthContext,java.awt.Graphics,int,int,int,int) [NONE]

paintBorder

public void paintBorder(SynthContext context,
                        Graphics g,
                        int x,
                        int y,
                        int w,
                        int h)

Paints the border.

Specified by:: paintBorder in interface SynthUI
Parameters:: context - a component context; g - Graphics to paint on; x - the X coordinate; y - the Y coordinate; w - width of the border; h - height of the border

method:getDefaultIcon(javax.swing.AbstractButton) [NONE]

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

method:getIcon(javax.swing.AbstractButton) [NONE]

getIcon
```
protected Icon getIcon(AbstractButton b)
```

an icon

method:getMinimumSize(javax.swing.JComponent) [NONE]

getMinimumSize
```
public Dimension getMinimumSize(JComponent c)
```
Returns the specified component's minimum size appropriate for the look and feel. If null is 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 invokes getPreferredSize and returns that value.

Overrides:

getMinimumSize in class BasicButtonUI

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 Dimension object or null

See Also:

JComponent.getMinimumSize(), LayoutManager.minimumLayoutSize(java.awt.Container), ComponentUI.getPreferredSize(javax.swing.JComponent)

method:getPreferredSize(javax.swing.JComponent) [NONE]

getPreferredSize
```
public Dimension getPreferredSize(JComponent c)
```
Returns the specified component's preferred size appropriate for the look and feel. If null is 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 returns null.

Overrides:

getPreferredSize in class BasicButtonUI

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

Returns:

a Dimension object containing given component's preferred size appropriate for the look and feel

See Also:

JComponent.getPreferredSize(), LayoutManager.preferredLayoutSize(java.awt.Container)

method:getMaximumSize(javax.swing.JComponent) [NONE]

getMaximumSize
```
public Dimension getMaximumSize(JComponent c)
```
Returns the specified component's maximum size appropriate for the look and feel. If null is 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 invokes getPreferredSize and returns that value.

Overrides:

getMaximumSize in class BasicButtonUI

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 Dimension object or null

See Also:

JComponent.getMaximumSize(), LayoutManager2.maximumLayoutSize(java.awt.Container)

method:getSizingIcon(javax.swing.AbstractButton) [NONE]

getSizingIcon
```
protected Icon getSizingIcon(AbstractButton b)
```
Returns the Icon used in calculating the preferred/minimum/maximum size.

Parameters:

b - specifies the AbstractButton used when calculating the preferred/minimum/maximum size.

Returns:

the Icon used in calculating the preferred/minimum/maximum size.

method:propertyChange(java.beans.PropertyChangeEvent) [NONE]

propertyChange
```
public void propertyChange(PropertyChangeEvent e)
```
This method gets called when a bound property is changed.

Specified by:

propertyChange in interface PropertyChangeListener
