public function get y():Number| ReshapeHandlerHandle | () | Constructor |
public function ReshapeHandlerHandle(position:uint, reshapeHandler:IReshapeHandler, minimumSize:ISize = null, maximumSize:ISize = null)Subclass constructor that creates a handle for the given position using the location instance as the location for the handle. The instance modifies the instances using the reshapeable interface and reads the current state using the rect. The handle will automatically trim changes of the rectangle to the specified minimum and maximum size.
Parametersposition:uint — The position of the handle.
| |
reshapeHandler:IReshapeHandler — The reshapeable to write the changes to.

minimumSize:ISize (default = null) | |
maximumSize:ISize (default = null) |
| cancelDrag | () | method |
public function cancelDrag(context:IInputModeContext, originalX:Number, originalY:Number):void
Delegates the cancel request to the IReshapeHandler.
Called by clients to indicate that the dragging has been canceled by the user.
This method may be called after the initial initializeDrag and zero or
more invocations of handleMove.
Implementations should reset the position of the items they modify to their initial state.
Alternatively to this method the dragFinished method might be called.
Parameters
context:IInputModeContext — The context to retrieve information about the drag from.
| |
originalX:Number — The value of the x property at the time of initializeDrag.
| |
originalY:Number — The value of the y property at the time of initializeDrag.
|

| dragFinished | () | method |
public function dragFinished(context:IInputModeContext, originalX:Number, originalY:Number, newX:Number, newY:Number):void
Delegates the finish request to the IReshapeHandler.
Called by clients to indicate that the repositioning has just been finished.
This method may be called after the initial initializeDrag and zero or
more invocations of handleMove.
Alternatively to this method the cancelDrag method might be called.
Parameters
context:IInputModeContext — The context to retrieve information about the drag from.
| |
originalX:Number — The value of the x property at the time of initializeDrag.
| |
originalY:Number — The value of the y property at the time of initializeDrag.
| |
newX:Number — The value of the x coordinate in the world coordinate system that the client wants the handle to be at.
Depending on the implementation the x and y properties or may not be modified to reflect the new value.
This is the same value as delivered in the last invocation of handleMove.
| |
newY:Number — The value of the y coordinate in the world coordinate system that the client wants the handle to be at.
Depending on the implementation the x and y properties or may not be modified to reflect the new value.
This is the same value as delivered in the last invocation of handleMove.

| handleMove | () | method |
public function handleMove(context:IInputModeContext, originalX:Number, originalY:Number, newX:Number, newY:Number):Boolean
Delegates the move request to the IReshapeHandler.handleReshape method.
Called by clients to indicate that the element has been dragged and its position
should be updated.
This method may be called more than once after an initial initializeDrag
and will be followed by either dragFinished or cancelDrag.
Parameters
context:IInputModeContext — The value of the x property at the time of initializeDrag.
| |
originalX:Number — The value of the y property at the time of initializeDrag.
| |
originalY:Number — The value of the x coordinate in the world coordinate system that the client wants the handle to be at.
Depending on the implementation the x property may or may not be modified to reflect the new value.
| |
newX:Number — The value of the y coordinate in the world coordinate system that the client wants the handle to be at.
Depending on the implementation the y property may or may not be modified to reflect the new value.
| |
newY:Number |
Boolean — Whether the move had any visual effect. This is a hint to the engine to optimize invalidation.
