所以我目前正在创建此API。这个登录类应该只创建一个包含所有需要的框的场景来制作GUI。我遇到的问题是我的形状在点击时不会做任何事情。我有事件监听器,但它不起作用。

答案 0 :(得分:1)
问题是您的Panes
互相重叠。当你这样称呼时:
shapes.getChildren().addAll(mainBox,cornerBox,clientBox,contractorBox);
contractorBox
(这是一个窗格)将位于顶部,消耗所有点击事件。
您应该在所有方法中使用相同的窗格。为此你可以使用像这样的成员:
private static Pane pane = new Pane();
然后例如在cornerBox
中:
pane.getChildren().addAll(cornerBox,cornerText);
这是针对此案例的解决方案,但是
整个班级看起来很奇怪。你为什么要扩展MainWindow?没有意义。还有为什么每一个都是静态的?
你需要什么,一个扩展任何Parent
(例如Group
)的类,它用你想要的每个控件填充Parent,并返回Parent。那么你可以在任何你想要的地方:
Scene scene = new Scene(new Login());
我也不明白为什么要绘制矩形和文本。你基本上需要的是两个按钮。您可以使用CSS修改按钮的外观:Example1,Example2。
