How to block a ScrollPane panel JavaFX

Question

I have a small problem. I'm building an interface with JavaFX like this: I wonder, how can I do to block those "lines" of the ScrollPane I indicated in the image? Practically it is not to be resizable but among its properties the ScrollPane does not allow me to put the check on that property:

How can I do to solve? thanks to all in advance!

I think your problem is that you have not added a minimum value to your ScrollPanes here's an example :

    SplitPane split = new SplitPane();
    split.setPrefSize(400, 400); 

    //First ScrollPane
    ScrollPane spA = new ScrollPane();
    spA.setMinWidth(100);  //Block the scrollPane width to 100
    spA.setFitToHeight(true);
    spA.setFitToWidth(true); 
    Pane paneA = new Pane();
    paneA.setStyle("-fx-background-color:red;");
    spA.setContent(paneA);

    //Second ScrollPane
    ScrollPane spB = new ScrollPane();
    spB.setMinWidth(100); //Block the scrollPane width to 100
    spB.setFitToHeight(true);
    spB.setFitToWidth(true); 
    Pane paneB = new Pane();
    paneB.setStyle("-fx-background-color:blue;");
    spB.setContent(paneB);

    split.getItems().addAll(spA,spB);

To be able to use your scrollPane as it grows, you can use the binding and bind the content's (width/height properties) of your ScrollPane to their parents (ScrollPane) example :

//set the (FitToHeight/FitToWidth) properties to false before !
spA.widthProperty().addListener(new ChangeListener<Number>() {

        @Override
        public void changed(ObservableValue<? extends Number> observable, Number oldValue, Number newValue) {

            paneB.setMinWidth((double)newValue);
        }
    });

Good luck !
