Method Detail

paint

public void paint(java.awt.Graphics2D g2d,
                  java.awt.Rectangle bounds,
                  E c,
                  D d,
                  java.awt.Shape shape)

Description copied from interface: IShadow

Paints shadow for the specified shape.

Parameters:

g2d - graphics context

bounds - painting bounds

c - painted component

d - painted decoration state

shape - background shape

getShadow

protected NinePatchIcon getShadow(java.awt.Rectangle bounds,
                                  int width,
                                  float opacity)

Returns cached shadow image. Image is updated if some related settings have changed.

Parameters:

bounds - shadow bounds

width - shadow width

opacity - shadow opacity

Returns:

cached shadow image

getShadowKey

protected static java.lang.String getShadowKey(java.awt.Rectangle b,
                                               int width,
                                               float opacity)

Returns shadow image cache key. It is optimized to only take bounds height and shadow width into account. Bounds width is not considered because it is always sufficient and should never really affect this shadow image.

Parameters:

b - shadow bounds

width - shadow width

opacity - shadow opacity

Returns:

shadow image cache key

getShadeCache

protected static NinePatchIcon getShadeCache(java.awt.Rectangle b,
                                             int width,
                                             float opacity)

Returns cached shadow image.

Parameters:

b - shadow bounds

width - shadow width

opacity - shadow opacity

Returns:

cached shadow image
