FXRotatePolicy

public FXRotatePolicy()

Method Detail

commit

public IUndoableOperation commit()

Description copied from interface: ITransactional

Returns an IUndoableOperation that performs all manipulations applied by the policy since the last ITransactional.init() call. When called multiple times in sequence, only the first call will yield an operation, the subsequent calls will yield null.

Specified by:

commit in interface ITransactional

Returns:

An IUndoableOperation that performs all manipulations applied by the policy since the last ITransactional.init() call.

getTransformPolicy

protected FXTransformPolicy getTransformPolicy()

Returns the FXTransformPolicy that is installed on the host.

Returns:

The FXTransformPolicy that is installed on the host.

init

public void init()

Description copied from interface: ITransactional

Initializes the policy, so that the policy's "work" methods can be used. Calling a "work" method while the policy is not initialized will result in an IllegalStateException. It is safe to call ITransactional.init() multiple times in sequence.

Specified by:

init in interface ITransactional

performRotation

public void performRotation(Angle rotationAngle,
                            Point pivotInScene)

Rotates the host by the given Angle around the given pivot Point.

Parameters:

rotationAngle - The rotation Angle.

pivotInScene - The pivot Point in scene coordinates.

updateOperation

protected void updateOperation(Angle rotationAngle,
                               Point pivotInHostVisual)

Applies the rotation given by the rotation Angle and the pivot Point to the host.

Parameters:

rotationAngle - The rotation Angle.

pivotInHostVisual - The pivot Point in host coordinates.
