GetStage() during initialize

Question

Hi,
when i try to write code like :
@FXML
Node node
@Override
public void initialize(URL url, ResourceBundle rb) {
   node.getStage();
}i receive a SEVERE: java.lang.NullPointerException.
So, how can i get stages during the initialization ?
thank you

Answer 1

may i try with a preloader?I think a Preloader would not help you with respect to the question "getStage() during initialize".
I tried adding a change listener, but it 's heavy (i've to add 2 nested listenerIn the (fairly common) case that your application just has one stage, you can probably record the stage as a static member of your application on startup, expose it via a getStage() method on the applicatio and then access it from your controller's initialize method via MyApplication.getStage(). Make sure you don't load any of your FXMLs until after the stage has been recorded for the application. This should be simple to implement and use.
If the above does not work for you, you will probably get better assistance if you also state why you are trying to do this and what the bigger picture of what you are trying to accomplish is.
