  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)
