java - JavaFX HBox hide item

Question

How can i hide an item in HBox, and made space used by this item available to other items.

TitledPane legendPane = new TitledPane("Legend", _legend);
legendPane.setVisible(false);
LineChart chart = new LineChart<Number, Number>(_xAxis, _yAxis);

HBox hbox = new HBox(5);
hbox.getChildren().addAll(legendPane, chart);

In the above code i want the chart node to use all available space when the legend pane is hidden.

Answer 1

Before calling legendPane.setVisible, call:

legendPane.managedProperty().bind(legendPane.visibleProperty());

The Node.managed property prevents a node in a Scene from affecting the layout of other scene nodes.
