public void setAppearance(FwkAppearanceInterface ap)

Set the appearance of the background.

Specified by:

setAppearance in interface P2DBackgroundInterface

Parameters:

ap - The appearance of the background.

getBoundingBox

public P2DBoundingBoxInterface getBoundingBox()

Retrieve the bounding box the component. The component must be alive to get a meaningful value.

Specified by:

getBoundingBox in interface P2DBackgroundInterface

Returns:

The bounding box.

setBoundingBox

public void setBoundingBox(P2DBoundingBoxInterface bb)

Set the the bounding box of the component.

Specified by:

setTransparency

public void setTransparency(float t)

Set the transparency. This method makes sense if the color is already set only. If the value is lower equal than 1 the method assumes that the transparency is specified in the range 0 .. 1.0. If the value is greater than 1 the method assumes the the transparency is specified in the range 1 .. 255.

Specified by:

setTransparency in interface P2DBackgroundInterface

Parameters:

t - The transparency.

getTransparency

public float getTransparency()

Get the transparency of the current color (range 0 .. 1.0). If no color is available the method returns 0.

Specified by:

getTransparency in interface P2DBackgroundInterface

Returns:

The transparency.
