Class SynthStyle

java.lang.Object
  extended by javax.swing.plaf.synth.SynthStyle

public abstract class SynthStyle
extends Object

SynthStyle is a set of style properties. Each SynthUI references at least one SynthStyle that is obtained using a SynthStyleFactory. You typically don't need to interact with this class directly, rather you will load a Synth File Format file into SynthLookAndFeel that will create a set of SynthStyles.

Since:
1.5

SynthLookAndFeel, SynthStyleFactory

Constructor Detail

SynthStyle

public SynthStyle()
Constructs a SynthStyle.

Method Detail

getGraphicsUtils

public SynthGraphicsUtils getGraphicsUtils(SynthContext context)
Returns the SynthGraphicUtils for the specified context.

Parameters:
context - SynthContext identifying requester
Returns:
SynthGraphicsUtils

getColor

public Color getColor(SynthContext context,
                      ColorType type)
Returns the color for the specified state. This gives precedence to foreground and background of the JComponent. If the Color from the JComponent is not appropriate, or not used, this will invoke getColorForState. Subclasses should generally not have to override this, instead override getColorForState(javax.swing.plaf.synth.SynthContext, javax.swing.plaf.synth.ColorType).

Parameters:
context - SynthContext identifying requester
type - Type of color being requested.
Returns:
Color

getColorForState

protected abstract Color getColorForState(SynthContext context,
                                          ColorType type)
Returns the color for the specified state. This should NOT call any methods on the JComponent.

Parameters:
context - SynthContext identifying requester
type - Type of color being requested.
Returns:
Color to render with

getFont

public Font getFont(SynthContext context)
Returns the Font for the specified state. This redirects to the JComponent from the context as necessary. If this does not redirect to the JComponent getFontForState(javax.swing.plaf.synth.SynthContext) is invoked.

Parameters:
context - SynthContext identifying requester
Returns:
Font to render with

getFontForState

protected abstract Font getFontForState(SynthContext context)
Returns the font for the specified state. This should NOT call any method on the JComponent.

Parameters:
context - SynthContext identifying requester
Returns:
Font to render with

getInsets

public Insets getInsets(SynthContext context,
                        Insets insets)
Returns the Insets that are used to calculate sizing information.

Parameters:
context - SynthContext identifying requester
insets - Insets to place return value in.
Returns:
Sizing Insets.

getPainter

public SynthPainter getPainter(SynthContext context)
Returns the SynthPainter that will be used for painting. This may return null.

Parameters:
context - SynthContext identifying requester
Returns:
SynthPainter to use

isOpaque

public boolean isOpaque(SynthContext context)
Returns true if the region is opaque.

Parameters:
context - SynthContext identifying requester
Returns:
true if region is opaque.

get

public Object get(SynthContext context,
                  Object key)
Getter for a region specific style property.

Parameters:
context - SynthContext identifying requester
key - Property being requested.
Returns:
Value of the named property

installDefaults

public void installDefaults(SynthContext context)
Installs the necessary state from this Style on the JComponent from context.

Parameters:
context - SynthContext identifying component to install properties to.

uninstallDefaults

public void uninstallDefaults(SynthContext context)
Uninstalls any state that this style installed on the JComponent from context.

Styles should NOT depend upon this being called, in certain cases it may never be called.

Parameters:
context - SynthContext identifying component to install properties to.

getInt

public int getInt(SynthContext context,
                  Object key,
                  int defaultValue)
Convenience method to get a specific style property whose value is a Number. If the value is a Number, intValue is returned, otherwise defaultValue is returned.

Parameters:
context - SynthContext identifying requester
key - Property being requested.
defaultValue - Value to return if the property has not been specified, or is not a Number
Returns:
Value of the named property

getBoolean

public boolean getBoolean(SynthContext context,
                          Object key,
                          boolean defaultValue)
Convenience method to get a specific style property whose value is an Boolean.

Parameters:
context - SynthContext identifying requester
key - Property being requested.
defaultValue - Value to return if the property has not been specified, or is not a Boolean
Returns:
Value of the named property

getIcon

public Icon getIcon(SynthContext context,
                    Object key)
Convenience method to get a specific style property whose value is an Icon.

Parameters:
context - SynthContext identifying requester
key - Property being requested.
Returns:
Value of the named property, or null if not specified

getString

public String getString(SynthContext context,
                        Object key,
                        String defaultValue)
Convenience method to get a specific style property whose value is a String.

Parameters:
context - SynthContext identifying requester
key - Property being requested.
