Question

我试图将3个功能组合到一个JavaFX类中。我的第一个特色是显示＆＃34;欢迎来到JAVA＆＃34;围成一圈。第二个显示随机1和0的10x10矩阵。第三个显示笑脸。它们应该在一个窗格中一个接一个地显示。我有第一和第三个功能，但矩阵一个让我失望。虽然一切都应该在一个窗格中显示在同一个GUI窗口（每位教授），但我不知道除了创建gridPane之外我还能做什么。它在没有大小限制的情况下显示正常，但随后它占据了整个屏幕，而我的其他两个功能都不可见。当我添加约束时，它变小并且数字不可见。我不知道如何解决这个问题。有人可以帮忙吗？

为每个功能创建一个窗格，然后将这些功能添加到VBox或HBox，这将是场景的根窗格。这样您就可以获得第二个功能的GridPane。 JavaFX中有不同的布局，它们的行为也不同。请查看此documentation及其子文档。
