Class | public class RectangleHandle |
Inheritance | RectangleHandle Object |
Implements | IMutablePoint, IMovable, IHandle |
IHandle
implementation that modifies a rectangle.
Implementations of this class work on a mutable rectangle instance, which they
use for both determining the position of the handle and for handling drags of the handle.
As a convenience this class also implements the IMutablePoint
and
IMovable
interface which both modify the handle's position.
Property | Defined By | ||
---|---|---|---|
cursor : Cursor [read-only]
Provides the cursor to display when the mouse hovers over or drags this
handle. | RectangleHandle | ||
type : uint [read-only]
Returns an appropriate type for this position. | RectangleHandle | ||
x : Number
The x coordinate of the position for this rectangle. | RectangleHandle | ||
y : Number
The y coordinate of the position for this rectangle. | RectangleHandle |

cancelDrag(context:IInputModeContext, originalX:Number, originalY:Number):void
This implementation calls setPosition using the original values. | RectangleHandle | ||
[static]
Creates a handle for the given position that uses and modifies the given instances that
are interpreted as a rectangle. | RectangleHandle | ||
[static]
Creates a handle for the given position that uses and modifies the rectangle instance
provided. | RectangleHandle | ||

RectangleHandle | () | Constructor |
public function RectangleHandle(index:uint, location:IPoint, size:ISize, reshapable:IReshapeable)
This constructor should only be used by subclasses.
Parametersindex:uint — The index of the handle's position. 0 is north-west and 8 is south-east.
| |
location:IPoint — The location of the upper left corner of the rectangle.
| |
size:ISize — The size of the rectangle.
| |
reshapable:IReshapeable — The reshapeable to write back the coordinates.
|
cancelDrag | () | method |
public function cancelDrag(context:IInputModeContext, originalX:Number, originalY:Number):void
This implementation calls setPosition
using the original values.
Parameters
context:IInputModeContext — The context to work with.
| |
originalX:Number — The original x coordinate.
| |
originalY:Number — The original y coordinate.
|
create | () | method |
public static function create(position:uint, location:IPoint, size:ISize, reshapable:IReshapeable):RectangleHandle
Creates a handle for the given position that uses and modifies the given instances that are interpreted as a rectangle.
The implementation uses the location and size to model the rectangle and writes changes to the geometry of the rectangle to the reshapeable.
Parameters
position:uint — The position to use for the handle.
| |
location:IPoint — The upper left corner of the rectangle.
| |
size:ISize — The size of the rectangle.
| |
reshapable:IReshapeable — The reshapeable to use for writing back changes of the handle.
|
RectangleHandle — A new instance that models a handle at the given position of the rectangle.
|

createFromRectangle | () | method |
public static function createFromRectangle(position:uint, rect:IMutableRectangle):RectangleHandle
Creates a handle for the given position that uses and modifies the rectangle instance provided.
Parameters
position:uint — The position to use for the handle.
| |
rect:IMutableRectangle — The rectangle that serves as a model for the handle.
|
RectangleHandle — A new instance that models a handle at the given position of the rectangle.
