startInStage

public void startInStage(javafx.stage.Stage stage)

Starts the flow directly in a Stage. This method is useful if an application contains of one main flow. Because this flow can contain several sub-flows this is the preferred way to create a DataFX based application. The title of the Stage will be bound to the title of the flow metadata and will change whenever the flow title fill change. This can happen if a view of the flow defines its own title by using the title attribute of the @FXMLController annotation or the ViewMetadata of an view is changed in code.

By using the method a flow based application can be created by only a few lines of code as shown in this example: public class Example extends Application { public static void main(String[] args) { launch(args); } public void start(Stage primaryStage) throws Exception { new Flow(SimpleController.class).startInStage(primaryStage); } }
