constructor:SynthLabelUI() [NONE]

SynthLabelUI

public SynthLabelUI()

Constructs a SynthLabelUI.

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

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

method:installDefaults(javax.swing.JLabel) [NONE]

installDefaults

protected void installDefaults (JLabel c)

Installs default properties.

Overrides:: installDefaults in class BasicLabelUI
Parameters:: c - an instance of JLabel

method:uninstallDefaults(javax.swing.JLabel) [NONE]

uninstallDefaults

protected void uninstallDefaults (JLabel c)

Uninstalls default properties.

Overrides:: uninstallDefaults in class BasicLabelUI
Parameters:: c - an instance of JLabel

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

getContext

public SynthContext getContext (JComponent c)

Returns the Context for the specified component.

Specified by:: getContext in interface SynthUI
Parameters:: c - Component requesting SynthContext.
Returns:: SynthContext describing component.

method:getBaseline(javax.swing.JComponent,int,int) [NONE]

getBaseline

public int getBaseline (JComponent c, int width, int height)

Returns the baseline.

Overrides:

getBaseline in class BasicLabelUI

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

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:

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 BasicLabelUI

Parameters:

g - the Graphics object used for painting

c - the component being painted

See Also:

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:

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: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 BasicLabelUI

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:

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 BasicLabelUI

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:

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 BasicLabelUI

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:

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
Overrides:: propertyChange in class BasicLabelUI
Parameters:: e - A PropertyChangeEvent object describing the event source and the property that has changed.
