这是我的主要课程

Class MainGuiFrame：

public class MainGuiFrame extends JFrame {
public static void main(String args[]) throws Exception {


    EventQueue.invokeLater(new Runnable() {
        public void run() {
            MainGuiFrame jf;
            try {
                jf = new MainGuiFrame();
                setLookAndFeel();
                jf.setVisible(true);
                jf.setExtendedState(JFrame.MAXIMIZED_BOTH);

            } catch (Exception e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

        }
    });
}

类CarsDrawingJpnl是一个JPanel，它包含一个绘图区域（JPanel）和相应的按钮（JPanel）

Class CarsDrawingJpnl：

public class CarsDrawingJpnl extends JPanel {

private CarsDrawingMap jpnlCarsMap;
private CarMapButtons jpnlCarMapCounterButtons;

private JScrollPane carDrawingScroller;
private JSplitPane jSplitPaneMapPlusFunctions;


private TwoJourneyModel twoJourneyCustomers;




public CarsDrawingJpnl(int width , int height) {


    this.setPreferredSize(new Dimension(width,height));//this is neccesary for the component to realize the size in practicality given in constructor
    this.setLayout(new BorderLayout());
    Border borScrollPane = BorderFactory.createEtchedBorder();
    this.setBorder(borScrollPane);
    //CAR MAP

    int widthJpnlMapButtons=width, heightJpnlMapButtons=height/6;

    int widthCarMap=width, heightCarMap = height-heightJpnlMapButtons;
    jpnlCarsMap = new CarsDrawingMap(this,widthCarMap,heightCarMap);

    carDrawingScroller = new JScrollPane( jpnlCarsMap);

    carDrawingScroller.getVerticalScrollBar().setUnitIncrement(5);
    carDrawingScroller.getVerticalScrollBar().setPreferredSize(new Dimension(30,5));
    carDrawingScroller.getHorizontalScrollBar().setUnitIncrement(7);
    carDrawingScroller.getHorizontalScrollBar().setPreferredSize(new Dimension(5,30));
    carDrawingScroller.setBorder(borScrollPane);


    jpnlCarMapCounterButtons= new CarMapButtons(this,widthJpnlMapButtons, heightJpnlMapButtons);
    DisabledPanel.disable(jpnlCarMapCounterButtons);

    //SPLIT BETWEEN MAP AND ALL FUNCTION BELOW
    jSplitPaneMapPlusFunctions= new JSplitPane(JSplitPane.VERTICAL_SPLIT);
//  jSplitPaneMapPlusFunctions.setDividerLocation(0.5);
    jSplitPaneMapPlusFunctions.setResizeWeight(0.70);

    jSplitPaneMapPlusFunctions.add(carDrawingScroller);

    this.add(jSplitPaneMapPlusFunctions, BorderLayout.CENTER);

当我运行我的主类时，Class CarsDrawingJpnl中使用的分割窗格的大小仅在运行程序开始时的当前选项卡中更新，如下图所示。

运行主JFrame类时的当前选项卡：

虽然其他标签不显示JSplitPane的实际重量，而其中三个标签是同一类的对象并以相同的方式实例化。另一个标签可以在下图中看到。

运行主JFrame类时的非当前选项卡：

我在运行主类时选择的任何一个标签都会显示更新的重量，而其余的则没有显示。

JSplitPane仅在创建时Jframe内部的JTabbedPane内的当前选项卡中显示实际权重
