initialized

protected boolean initialized

Stores the initialized flag for this policy, i.e. true after init() was called, and false after commit() was called, respectively.

FXScaleRelocatePolicy

public FXScaleRelocatePolicy()

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.

getResizePolicy

protected FXResizePolicy getResizePolicy()

Returns the FXResizePolicy that is installed on the host.

Returns:

The FXResizePolicy that is installed on the host.

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

performScaleRelocate

public void performScaleRelocate(javafx.geometry.Bounds oldBoundsInScene,
                                 javafx.geometry.Bounds newBoundsInScene)

Applies a scale/relocate transformation to its host. The transformation reflects the transformation from the given old Bounds to the given new Bounds.

Parameters:

oldBoundsInScene - The old Bounds of the host.

newBoundsInScene - The new Bounds of the host.
