Method Detail

getId

int getId()

Returns the unique id of this object

Returns:

getWidth

float getWidth()

Returns the width of this object

Returns:

0 by default

getHeight

float getHeight()

Returns the height of this object

Returns:

0 by default

setRadius

void setRadius(float radius)

Sets the radius of this shape. For Polygon shapes, this will stretch in/out the shape from its center. Note that Polygons must be equilateral.

Parameters:

radius - The radius in pixels

scale

void scale(float scale)

Scales the radius of this shape. For Polygon shapes, this will stretch in/out the shape from its center. Note that Polygons must be equilateral.

Parameters:

scale - The amount to scale by (e.g. 2.0 = double the size)

getMinX

float getMinX()

Returns min X coordinate of this object

Returns:

The left-most x coordinate

getMinY

float getMinY()

Returns min Y coordinate of this object

Returns:

The up-most y coordinate

getMaxX

float getMaxX()

Returns max X coordinate of this object

Returns:

The right-most x coordinate

getMaxY

float getMaxY()

Returns max Y coordinate of this object

Returns:

The bottom-most y coordinate

getCenterX

float getCenterX()

Returns the center x coordinate of this object. Note for Circle this is the same as x.

Returns:

0 by default

getCenterY

float getCenterY()

Returns the center y coordinate of this object. Note for Circle this is the same as y.

Returns:

0 by default

setCenter

void setCenter(float x,
               float y)

Sets the center x,y coordinate of this object

Parameters:

x - The x coordinate of the shape's center

y - The y coordinate of the shape's center

setCenterX

void setCenterX(float x)

Sets the center x coordinate

Parameters:

x - The x coordinate of the shape's center

setCenterY

void setCenterY(float y)

Sets the center y coordianate

Parameters:

y - The y coordinate of the shape's center

addSizeChangeListener

<T extends Sizeable> void addSizeChangeListener(SizeChangeListener<T> listener)

Adds a SizeChangeListener to be notified of size changes

Parameters:

listener - The SizeChangeListener to add

removeSizeChangeListener

<T extends Sizeable> void removeSizeChangeListener(SizeChangeListener<T> listener)

Removes a SizeChangeListener to stop it being notified of size changes

Parameters:

listener - The SizeChangeListener to remove
