SynthLabelUI
public SynthLabelUI()
Methods
createUI
public static ComponentUI createUI(JComponent c)
Returns the LabelUI implementation used for the skins look and feel.
- Parameters:
-
c
- component to create UI object for - Returns:
- the UI object
installDefaults
protected void installDefaults(JLabel c)
Installs default properties.
- Overrides:
-
installDefaults
in classBasicLabelUI
- Parameters:
-
c
- an instance ofJLabel
uninstallDefaults
protected void uninstallDefaults(JLabel c)
Uninstalls default properties.
- Overrides:
-
uninstallDefaults
in classBasicLabelUI
- Parameters:
-
c
- an instance ofJLabel
getContext
public SynthContext getContext(JComponent c)
Returns the Context for the specified component.
- Specified by:
-
getContext
in interfaceSynthUI
- Parameters:
-
c
- Component requesting SynthContext. - Returns:
- SynthContext describing component.
getBaseline
public int getBaseline(JComponent c, int width, int height)
Returns the baseline.
- Overrides:
-
getBaseline
in classBasicLabelUI
- Parameters:
-
c
-JComponent
baseline is being requested for -
width
- the width to get the baseline for -
height
- 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 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 classComponentUI
- Parameters:
-
g
- theGraphics
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 classBasicLabelUI
- Parameters:
-
g
- theGraphics
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.
- Parameters:
-
context
- context for the component being painted -
g
- theGraphics
object used for painting - See Also:
update(Graphics,JComponent)
paintBorder
public void paintBorder(SynthContext context, Graphics g, int x, int y, int w, int h)
Paints the border.
- Specified by:
-
paintBorder
in interfaceSynthUI
- 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
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 classBasicLabelUI
- 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)
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 classBasicLabelUI
- 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:
- getPreferredSize(c)
- See Also:
-
JComponent.getMinimumSize()
,LayoutManager.minimumLayoutSize(java.awt.Container)
,ComponentUI.getPreferredSize(javax.swing.JComponent)
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 classBasicLabelUI
- 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:
- getPreferredSize(c)
- See Also:
-
JComponent.getMaximumSize()
,LayoutManager2.maximumLayoutSize(java.awt.Container)
propertyChange
public void propertyChange(PropertyChangeEvent e)
This method gets called when a bound property is changed.
- Specified by:
-
propertyChange
in interfacePropertyChangeListener
- Overrides:
-
propertyChange
in classBasicLabelUI
- Parameters:
-
e
- A PropertyChangeEvent object describing the event source and the property that has changed.
