ListView不会在Java FX中更改其大小

Question

我在VBox中添加了一个ListView，它位于BorderPane的左侧。它实际上运行良好，但如果我在应用程序运行时更改窗口大小，我遇到的问题是ListView不会更改其大小。谁能帮我解决这个问题？:)代码：

package main;

公共类ScreenBuilder扩展了Application {

BorderPane parent;
    HBox top;
    HBox bottom;
    VBox left;
        ScrollPane pane;
        ListView<String> list;
    VBox right;

@Override
public void start(Stage stage) throws Exception {
    // TODO Auto-generated method stub

    parent = new BorderPane();
    parent.setStyle("-fx-border-width: 2px; -fx-border-color: #2e8b57");

        top = new HBox();
        parent.setTop(top);


        bottom = new HBox();
        parent.setBottom(bottom);


        left = new VBox();
        parent.setLeft(left);

            list = new ListView<String>(initList());
            pane = new ScrollPane(list);
            pane.setStyle("-fx-border-width: 2px; -fx-border-color: #2e8b57");
            left.getChildren().add(pane);


        right = new VBox();
        parent.setRight(right);


    stage.setScene(new Scene(parent));
    stage.show();

}

private ObservableList<String> initList(){
    ObservableList list = FXCollections.observableArrayList();
    list.add("Hallo1");
    list.add("Hallo2");
    list.add("Hallo3");
    list.add("Hallo4");
    list.add("Hallo5");
    list.add("Hallo6");
    list.add("Hallo7");
    list.add("Hallo8");
    list.add("Hallo9");
    return list;
}





public static void main(String[] args){
    launch();
}

}
