How do I get a reference to my controller class?
Here is my code snippet.
Parent root = FXMLLoader.load(getClass().getResource("my.fxml"));
stage.setScene(new Scene(root, 500, 500));
MyController c = stage.getControllerInstance(); <-- HOW???
c.setATextValue("Hello world"); //Set initial value
stage.show();
The Controller class is specified in FXML in the fx:controller attribute. The instance gets created automatically in the background. I need access to that instance in order to set initial values in the form.
I know I can set the initial values in XML, but I need to set them at runtime.
Don't use the static FXMLLoader.load(...)
method. Instead, create an FXMLLoader
instance and call load()
on the instance. Then you can call getController()
:
FXMLLoader loader = new FXMLLoader(getClass().getResource("my.fxml"));
Parent root = loader.load();
MyController c = loader.getController();
stage.setScene(new Scene(root, 500, 500));
