Overrides javafx.scene.control.skin.VirtualContainerBase.createVirtualFlow.

Doc from javafx.scene.control.skin.VirtualContainerBase.createVirtualFlow.

Create the virtualized container that handles the layout and scrolling of all the cells. This enables skin subclasses to provide a custom VirtualFlow implementation. If not overridden, this method instantiates a default VirtualFlow instance.

public void rebuildCells()

Overrides javafx.scene.control.skin.VirtualFlow.rebuildCells.

Doc from javafx.scene.control.skin.VirtualFlow.rebuildCells.

Informs the VirtualFlow that a layout pass should be done, and cell contents have changed. All cells are removed and then added properly in the viewport.

public void reconfigureCells()

Overrides javafx.scene.control.skin.VirtualFlow.reconfigureCells.

Doc from javafx.scene.control.skin.VirtualFlow.reconfigureCells.

Informs the VirtualFlow that a layout pass should be done, and the cell contents have not changed. For example, this might be called from a TableView or ListView when a layout is needed and no cells have been added or removed.

recreateCellsback to summary
public void recreateCells()

Overrides javafx.scene.control.skin.VirtualFlow.recreateCells.

Doc from javafx.scene.control.skin.VirtualFlow.recreateCells.

Informs the VirtualFlow that a layout pass should be done, and that the cell factory has changed. All cells in the viewport are recreated with the new cell factory.
