How to use

getMax

method

in

javafx.scene.control.ScrollBar

  @Override
  protected double computeValue() {
    double max = bar.getMax();
    double visible = bar.getVisibleAmount();
    return max > visible
        ? 16 / (max - visible) * max
        : 0;
  }
});

 updateTextAreaTask.messageProperty().addListener(new ChangeListener<String>() {
  @Override
  public void changed(ObservableValue<? extends String> obs, String oldMessage, String newMessage) {
    taProgressText.setText(newMessage);
    ScrollBar scrollBar = (ScrollBar) taProgressText.lookup(".scroll-bar:vertical");
    if (scrollBar != null) {
      scrollBar.setValue(scrollBar.getMax());
    }
  }
});

scrollBar.setMax(scrollBar1.getMax());

scrollBar.setMax(TOTAL_WIDTH - canvas.getWidth());
