Center stage on parent stage

You can use the parent stage’s X/Y/width/height properties to do that. Rather than using Stage#centerOnScreen, you could do the following: public class CenterStage extends Application { @Override public void start(final Stage stage) throws Exception { stage.setX(300); stage.setWidth(800); stage.setHeight(400); stage.show(); final Stage childStage = new Stage(); childStage.setWidth(200); childStage.setHeight(200); childStage.setX(stage.getX() + stage.getWidth() / 2 – childStage.getWidth() / … Read more

How to get stage from controller during initialization?

You can get the instance of the controller from the FXMLLoader after initialization via getController(), but you need to instantiate an FXMLLoader instead of using the static methods then. I’d pass the stage after calling load() directly to the controller afterwards: FXMLLoader loader = new FXMLLoader(getClass().getResource(“MyGui.fxml”)); Parent root = (Parent)loader.load(); MyController controller = (MyController)loader.getController(); controller.setStageAndSetupListeners(stage); … Read more
