java - JPanels显示问题

Question

我正在开发一款小游戏。我已经快完成了，但我面临的剩余问题可以分为三个:

1. 当我执行游戏时，窗口上什么也没有显示，只有灰色背景，当我缩小它并再次单击它时，我找到了通常应该看到的内容；所有面板都有这个问题，例如从游戏面板移动到得分面板我应该再次减少它......
2. 速度很慢!特别是当我输球时它需要计算分数并需要显示我更新的 ScorePanel。
3. 我无法执行生成的 JAR 文件，我尝试了一段时间的解决方案但没有成功

这是我的代码的三个主要类:

JFrame代码

public class Fenetre extends JFrame {

    private JMenuBar menu = new JMenuBar();
    private JMenu file = new JMenu("Fichier");
    private JMenuItem neew = new JMenuItem("Nouveau");

    private JMenuItem how = new JMenuItem("Règles");
    private JMenuItem who = new JMenuItem("Credit");
    private int i=1;
    private ScorePanel scorepan = new ScorePanel(900,650);
    private ReglesJeuPanel rgpan = new ReglesJeuPanel(900,650);
    private GamePanel gamepan = new GamePanel();
    private JPanel pan = new JPanel();
    private JPanel container = new JPanel();
    private JLabel label = new JLabel("------------------------SAMAIKOM------------------------");
    private JTextArea texte = new JTextArea(    "Vous avez sept coups pour trouver le mot caché. Si vous réussissez, on recommence !\n" +
            "Plus vous trouvez de mots, plus votre score augmente. Alors, à vous de jouer !\n" +
            "Proverbe :\t« Pas vu, pas pris !\n" +

Answer 1

The first one is, when I execute my game, nothings shows up on the window just a gray background, when I reduce it and clic on it again, I find what normally I should see; and this problem with all the panels, for exemple to move from the game panel to the score panel I should reduce it again ...

这通常是在您实际向窗口添加任何内容之前调用 setVisible(true) 的症状...

The third problem is that I cannot execute my generated JAR file, I sought a sollution for a while but in vain

这可能是因为您未能向 mainfest 文件提供 Main-Class 条目。看看Setting an Application's Entry Point

== 不是 Java 中 String 比较的方式，而是您想要使用 String#equals，例如...

if (mistakeslabel == label3.getText()) {...

应该是

if (mistakeslabel.equals(label3.getText())) {...

The second problem is that it is slow ! especially if it needs to calculate score when I lose and seeds to display my updated scorepanel ...

这还不清楚，但我怀疑，如果您在更改面板后调用 revalidate 和 repaint 或使用 CardLayout，您可能会发现这样效果更好
