问题描述

我正在编写一个应用程序（虚拟诊所），但我不知道如何注入FXML文件（在MainController.FXML中注入），该文件将在单击按钮后显示，之前我将其注入到Main.FXML的Button行之间，但是它不起作用，我是说它确实起作用，但是随后包含的FXML始终可见，并且我想以CheckOutPatient.FXML在Main.FXML中的“ optionPane”空间中单击“ checkoutButton”时将可见，这是一个代码：

Main.FXML：

这个RegistrationController： 

@FXML
public void handleAddPatient(ActionEvent event) {

    infoPatientController.infoageField.setText("asdf");
 }

这是错误：

尝试以下代码： 

// creating a loader for the scene you want to change
FXMLLoader loader = new FXMLLoader(getClass().getResource("yourScene.fxml"));

// creating a controller to be called to customize that scene's elements
MainController controller = (MainController)loader.getController();

现在您可以执行以下操作： 

controller.yourButton.setText("...");

希望这可以帮助！
