默认大小的窗口

然后

窗口最大化

我创建了一个键来显示控件的包含：

这里

我希望VBoxs内部的列表视图在保持其比率的同时增长。

以下是代码：

代码语言：javascript
运行
复制
public class Modules extends BorderPane {

private Button Term1AddBtn, Term2AddBtn, Term2AddBtn, Term2RemoveBtn, ResetBtn, SubmitBtn;
private ListView Term1UnSelect, Term2UnSelect, Term1Select, Term2Select, YearSelect;
private TextField txtTerm1Cred, txtTerm1Cred;

public Modules() {
    FlowPane flowPane = new FlowPane(Orientation.VERTICAL);
    flowPane.setHgap(20);
    flowPane.setVgap(20);
    this.setPadding(new Insets(0, 10, 20, 10)); 

    Label lblTerm1UnSel = new Label("Unselected Term 1 Modules");
    Label lblTerm2UnSel = new Label("Unselected Term 2 Modules");
    Label lblTerm1Sel   = new Label("Selected Term 1 Modules");
    Label lblTerm2Sel   = new Label("Selected Term 2 Modules");
    Label lblYearSel   = new Label("Selected Year Long Modules");
    Label lblTerm1Btns  = new Label("Term 1:");
    Label lblTerm2Btns  = new Label("Term 2:");
    Label lblTerm1Cred  = new Label("Current Term 1 Credits:");
    Label lblTerm2Cred  = new Label("Current Term 2 Credits:");

    Term1UnSelect = new ListView();
    Term2UnSelect = new ListView();
    Term1Select = new ListView();
    Term2Select = new ListView();
    YearSelect = new ListView();
    Term1AddBtn  = new Button("Add");
    Term1RemoveBtn   = new Button("Remove");
    Term2AddBtn  = new Button("Add");
    Term2RemoveBtn   = new Button("Remove");
    ResetBtn    = new Button("Reset");
    SubmitBtn    = new Button("Submit");
    txtTerm1Cred = new TextField("0");
    txtTerm1Cred = new TextField("0");


    Term1UnSelect.setPrefSize(350, 100);
    Term2UnSelect.setPrefSize(350, 100);
    Term1Select.setPrefSize(350, 100);
    Term2Select.setPrefSize(350, 100);
    YearSelect.setPrefSize(350, 50);
    txtTerm1Cred.setMaxWidth(50);
    txtTerm1Cred.setMaxWidth(50);
    Term1AddBtn.setPrefWidth(70);
    Term1RemoveBtn.setPrefWidth(70);
    Term2AddBtn.setPrefWidth(70);
    Term2RemoveBtn.setPrefWidth(70);
    ResetBtn.setPrefWidth(70);
    SubmitBtn.setPrefWidth(70);

    VBox vboxTerm1Unsel = new VBox();
    VBox vboxTerm2Unsel = new VBox();
    VBox vboxTerm1Sel   = new VBox();
    VBox vboxTerm2Sel   = new VBox();
    VBox vboxYear   = new VBox();
    HBox hboxTerm1Btns  = new HBox();
    HBox hboxTerm2Btns  = new HBox();
    HBox hboxTerm1Cred  = new HBox();
    HBox hboxTerm2Cred  = new HBox();
    HBox hboxResetSubmit= new HBox();

    hboxTerm1Btns.setSpacing(20);
    hboxTerm2Btns.setSpacing(20);
    hboxTerm1Cred.setSpacing(20);
    hboxTerm2Cred.setSpacing(20);
    hboxResetSubmit.setSpacing(20);

    vboxTerm1Unsel.getChildren().addAll(lblTerm1UnSel, Term1UnSelect);
    vboxTerm2Unsel.getChildren().addAll(lblTerm2UnSel, Term2UnSelect);
    vboxTerm1Sel.getChildren().addAll(lblTerm1Sel, Term1Select);
    vboxTerm2Sel.getChildren().addAll(lblTerm2Sel, Term2Select);
    vboxYear.getChildren().addAll(lblYearSel, YearSelect);
    hboxTerm1Btns.getChildren().addAll(lblTerm1Btns, Term1AddBtn, Term1RemoveBtn);
    hboxTerm2Btns.getChildren().addAll(lblTerm2Btns, Term2AddBtn, Term2RemoveBtn);
    hboxTerm1Cred.getChildren().addAll(lblTerm1Cred, txtTerm1Cred);
    hboxTerm2Cred.getChildren().addAll(lblTerm2Cred, txtTerm1Cred);
    hboxResetSubmit.getChildren().addAll(ResetBtn, SubmitBtn);

    hboxTerm1Btns.setAlignment(Pos.CENTER);
    hboxTerm2Btns.setAlignment(Pos.CENTER);
    hboxTerm1Cred.setAlignment(Pos.CENTER);
    hboxTerm2Cred.setAlignment(Pos.CENTER);
    hboxResetSubmit.setAlignment(Pos.CENTER);

    flowPane.getChildren().addAll(vboxTerm1Unsel, hboxTerm1Btns, vboxTerm2Unsel, hboxTerm2Btns, hboxTerm1Cred, vboxYear, vboxTerm1Sel, vboxTerm2Sel, hboxTerm2Cred);

    BorderPane.setMargin(flowPane, new Insets(20));

    this.setCenter(flowPane);
    this.setBottom(hboxResetSubmit);

}

或者，如果可能的话，以如下方式将控件保持在相同的格式：

就像这样

}

你可以在这两种情况下使用间距。
