无法与JavaFX控件交互-可能存在.fxml布局问题
无法与JavaFX控件交互-可能存在.fxml布局问题
提问于 2015-03-31 02:50:55
我曾经有一个RootLayout边框窗格，上面有一个fx:includes Anchor窗格，上面有我的控制器。我试图将这两个文件合并到一个.fxml文件中，但我在尝试与应用程序的上半部分交互时遇到了问题(按钮、组合框等不可点击)。我假设我的组织有问题，或者甚至是失误，但我没有意识到这一点，这是我的第一个javaFX应用程序。如果我在JavaFX场景生成器中打开.fxml，我只能在层次中看到边界窗格。
下面是包含两个.fxml文件的旧设置

我想通了。我有一个额外的锚板，它不喜欢。我删除了以下代码；
