setMinSize()是否适用于容器,例如GridPane？我发现在我的程序中GridPane忽略了min.手动调整大小时的大小属性.这是FXML代码:

<GridPane fx:id="gp" prefHeight="134.0" prefWidth="238.0" xmlns:fx="http://javafx.com/fxml" fx:controller="javafxapplication12.SampleController">
  <columnConstraints>
    <ColumnConstraints hgrow="SOMETIMES" minWidth="10.0" prefWidth="100.0" />
    <ColumnConstraints hgrow="SOMETIMES" minWidth="10.0" prefWidth="100.0" />
  </columnConstraints>
  <rowConstraints>
    <RowConstraints minHeight="10.0" prefHeight="30.0" vgrow="SOMETIMES" />
    <RowConstraints minHeight="10.0" prefHeight="30.0" vgrow="SOMETIMES" />
    <RowConstraints minHeight="10.0" prefHeight="30.0" vgrow="SOMETIMES" />
  </rowConstraints>
</GridPane>

和控制器类

public class SampleController implements Initializable {

    @FXML
    private GridPane gp;

    @Override
    public void initialize(URL url, ResourceBundle rb) {
    gp.setMaxWidth(700);
    gp.setMinSize(200, 200);
    }   

这有什么不对？应该有某种"窗口"最大/最小尺寸？
