Constructor Detail

GradientPanel

public GradientPanel()

Creates a GradientPanel object. This is the default constructor. The initial and final colors are set to Color.white, and there is no gradient effect.

GradientPanel

public GradientPanel(java.awt.Color initialColor,
                     java.awt.Color finalColor)

Creates a GradientPanel object. The initial and final colors of the gradient colors effect must be passed to the constructor.

Parameters:

initialColor - A Color object.

finalColor - A Color object.

GradientPanel

public GradientPanel(java.awt.Color initialColor,
                     java.awt.Color finalColor,
                     int orientation)

Creates a GradientPanel object. This constructor takes the initial and final colors as well as the gradient effect orientation.

Parameters:

initialColor - A Color object.

finalColor - A Color object.

orientation - An integer number.

See Also:

TOP_TO_BOTTOM, BOTTOM_TO_TOP, LEFT_TO_RIGHT, RIGHT_TO_LEFT

Method Detail

setGradientOrientation

public void setGradientOrientation(int orientation)

Sets gradient colors orientation. Default value is TOP_TO_BOTTOM.

Parameters:

orientation - An integer number.

See Also:

TOP_TO_BOTTOM, BOTTOM_TO_TOP, LEFT_TO_RIGHT, RIGHT_TO_LEFT

setGradientColors

public void setGradientColors(java.awt.Color initialColor,
                              java.awt.Color finalColor)

Sets initial and final colors of the gradient colors effect.

Parameters:

initialColor - A Color object.

finalColor - A Color object.

paint

public void paint(java.awt.Graphics g)

Overrides the Component class paint() method to provide gradient effect.

Parameters:

g - A Graphics object.

finalize

protected void finalize()
                 throws java.lang.Throwable

Throws:

java.lang.Throwable
