Method Detail

• getWindow

  protected Window getWindow(Component c)

• whenDisplayable

  protected void whenDisplayable(Component w,
                     Runnable action)

  Execute the given action when the given window becomes displayable.

• toRaster

  protected Raster toRaster(Shape mask)

• toRaster

  protected Raster toRaster(Component c,
                Icon mask)

• toShape

  protected Shape toShape(Raster raster)

• setWindowAlpha

  public void setWindowAlpha(Window w,
                    float alpha)

  Set the overall alpha transparency of the window. An alpha of 1.0 is fully opaque, 0.0 is fully transparent.

• isWindowAlphaSupported

  public boolean isWindowAlphaSupported()

  Default: no support.

• getAlphaCompatibleGraphicsConfiguration

  public GraphicsConfiguration getAlphaCompatibleGraphicsConfiguration()

  Return the default graphics configuration.

• setWindowTransparent

  public void setWindowTransparent(Window w,
                          boolean transparent)

  Set the window to be transparent. Only explicitly painted pixels will be non-transparent. All pixels will be composited with whatever is under the window using their alpha values.

• setDoubleBuffered

  protected void setDoubleBuffered(Component root,
                       boolean buffered)

• setLayersTransparent

  protected void setLayersTransparent(Window w,
                          boolean transparent)

• setMask

  protected void setMask(Component c,
             Raster raster)

  Override this method to provide bitmap masking of the given heavyweight component.

• setWindowMask

  protected void setWindowMask(Component w,
                   Raster raster)

  Set the window mask based on the given Raster, which should be treated as a bitmap (zero/nonzero values only). A value of null means to remove the mask.

• setWindowMask

  public void setWindowMask(Component w,
                   Shape mask)

  Set the window mask based on a Shape.

• setWindowMask

  public void setWindowMask(Component w,
                   Icon mask)

  Set the window mask based on an Icon. All non-transparent pixels will be included in the mask.

• setForceHeavyweightPopups

  protected void setForceHeavyweightPopups(Window w,
                               boolean force)

  Use this method to ensure heavyweight popups are used in conjunction with a given window. This prevents the window's alpha setting or mask region from being applied to the popup.
