Constructor Detail

ReshapeHandlerHandle

public ReshapeHandlerHandle(HandlePositions position,
                            IReshapeHandler reshapeHandler)

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.

Parameters:

position - The position of the handle.

reshapeHandler - The reshapeable to write the changes to.

ReshapeHandlerHandle

public ReshapeHandlerHandle(HandlePositions position,
                            IReshapeHandler reshapeHandler,
                            ISize minimumSize)

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.

Parameters:

position - The position of the handle.

reshapeHandler - The reshapeable to write the changes to.

minimumSize - The minimum size allowed for the rectangle.

ReshapeHandlerHandle

public ReshapeHandlerHandle(HandlePositions position,

                            ISize minimumSize,
                            ISize maximumSize)

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.

Parameters:

position - The position of the handle.

reshapeHandler - The reshapeable to write the changes to.

maximumSize - The maximum size allowed for the rectangle.

minimumSize - The minimum size allowed for the rectangle.

Method Detail

cancelDrag

public void cancelDrag(IInputModeContext context,
                       PointD originalLocation)

Delegates the cancel request to the IReshapeHandler.

Specified by:

cancelDrag in interface IDragHandler

Parameters:

context - The context to retrieve information about the drag from.

originalLocation - The value of the coordinate of the Location property at the time of IDragHandler.initializeDrag(IInputModeContext).

dragFinished

public void dragFinished(IInputModeContext context,
                         PointD originalLocation,
                         PointD newLocation)

Delegates the finish request to the IReshapeHandler.

Specified by:

dragFinished in interface IDragHandler

Parameters:

context - The context to retrieve information about the drag from.

originalLocation - The value of the Location property at the time of IDragHandler.initializeDrag(IInputModeContext).

newLocation - The coordinates in the world coordinate system that the client wants the handle to be at. Depending on the implementation the Location may or may not be modified to reflect the new value. This is the same value as delivered in the last invocation of IDragHandler.handleMove(IInputModeContext, PointD, PointD)

getCursor

public final Cursor getCursor()

Gets the cursor to display when the mouse hovers over or drags this handle.

Parameters:

context - The context to retrieve information about the drag from.

originalLocation - The value of the Location property at the time of IDragHandler.initializeDrag(IInputModeContext).
