FXResizePolicy

public FXResizePolicy()

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 AbstractTransactionPolicy<javafx.scene.Node>

Returns:

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

createOperation

protected ITransactionalOperation createOperation()

Description copied from class: AbstractTransactionPolicy

Creates an ITransactionalOperation that is used to encapsulate the changes that are applied by this AbstractTransactionPolicy through its "work" methods. The created operation should allow for local execution at each time.

Specified by:

createOperation in class AbstractTransactionPolicy<javafx.scene.Node>

Returns:

A new ITransactionalOperation to encapsulate all applied changes.

getMinimumHeight

protected double getMinimumHeight()

Returns the minimum height. The height of a Node cannot be changed below this limit.

Returns:

The minimum height.

getMinimumWidth

protected double getMinimumWidth()

Returns the minimum width. The width of a Node cannot be changed below this limit.

Returns:

The minimum width.

getResizeOperation

protected FXResizeNodeOperation getResizeOperation()

Returns the FXResizeNodeOperation that is used by this FXResizePolicy.

Returns:

The FXResizeNodeOperation nested within the ITransactionalOperation used by this AbstractTransactionPolicy.

getSize

protected Dimension getSize(javafx.scene.Node visualToResize)

Returns the current size of the passed-in Node, i.e. the width and height of its layout-bounds.

Parameters:

visualToResize - The Node for which to return the current size.

Returns:

The current size of the passed-in Node.

getVisualToResize

protected javafx.scene.Node getVisualToResize()

Returns the Node that should be resized. Per default, this is the host's visual.

Returns:

The Node that should be resized.

resize

public void resize(double dw,
                   double dh)

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

Parameters:

dw - The delta width.

dh - The delta height.
