FXResizeConnectionPolicy

public FXResizeConnectionPolicy()

Method Detail

commit

public ITransactionalOperation commit()

Description copied from class: AbstractTransactionPolicy

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

Overrides:

commit in class FXResizePolicy

Returns:

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

getIndicesOfMovableAnchors

protected java.util.List<java.lang.Integer> getIndicesOfMovableAnchors()

Returns the indices of all movable anchors. Only those anchors are relocated by this policy.

Returns:

List of Integers specifying the anchors to relocate.

init

public void init()

Description copied from class: AbstractTransactionPolicy

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 AbstractTransactionPolicy.init() multiple times in sequence.

Overrides:

init in class AbstractTransactionPolicy<javafx.scene.Node>

resize

public void resize(double dw,
                   double dh)

Description copied from class: FXResizePolicy

Resizes the visual by the given delta width and delta height.

Overrides:

resize in class FXResizePolicy

Parameters:

dw - The delta width.

dh - The delta height.
