Method Detail

paint

void paint(java.awt.Graphics2D g)

Paint the background.

Parameters:

g - The graphics context.

getAppearance

FwkAppearanceInterface getAppearance()

Get the appearance of the background.

Returns:

The appearance of the background.

setAppearance

void setAppearance(FwkAppearanceInterface ap)

Set the appearance of the background.

Parameters:

ap - The appearance of the background.

getBoundingBox

P2DBoundingBoxInterface getBoundingBox()

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

Returns:

The bounding box.

setBoundingBox

void setBoundingBox(P2DBoundingBoxInterface bb)

Set the the bounding box of the component.

Parameters:

bb - The new bounding box of the component.

isVisible

boolean isVisible()

Returns a boolean whether the object is visible.

Returns:

true if the object is visible.

setVisible

void setVisible(boolean flag)

Sets the visibility of the background.

Parameters:

flag - The flag that indicates the visiblity of the background.

getVisible

boolean getVisible()

Retrieves the visibility of the background.

Returns:

true if the background is visible.

setColor

void setColor(java.awt.Color c)

Sets this graphics context's current color to the specified color.

Parameters:

c - the color.

getColor

java.awt.Color getColor()

Gets this graphics context's current color to the specified color.

Returns:

the color.

Color

setTransparency

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.

Parameters:

t - The transparency.

getTransparency

float getTransparency()

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

Returns:

The transparency.
