One controller to 2 fxmls (JavaFX)

阅读更多关于 One controller to 2 fxmls (JavaFX)

Is possible to connect two FXML (JavaFX) files to one controller? I can't do this with changing "fx:controller" in each FXML file... Any ideas? jewelsea Yes, you can do this. Although, it can be done, I do not recommend this approach . Don't place a fx:controller attribute in either FXML. Create a new controller and set the same controller into separate FXMLLoader instances. CustomerDialogController dialogController = new CustomerDialogController(param1, param2); FXMLLoader summaryloader = new FXMLLoader( getClass().getResource( "customerSummary.fxml" ) ); summaryLoader.setController

Have multiple FXML files (created in SceneBuilder), but only one controller. Does each scene load it's own copy of the controller?

阅读更多关于 Have multiple FXML files (created in SceneBuilder), but only one controller. Does each scene load it's own copy of the controller?

I have multiple FXML files I have created in SceneBuilder and one controller file. When I edit a value (say for instance, an integer value) in one scene, and then switch scenes, that value does not seem to have been changed in the new scene. When loading the fxml file for a scene, is my program loading a copy of the controller file just for (and used only by) that fxml file? Really appreciate any help you guys can give answering this question. jewelsea Your controller file is a Java source file which gets compiled to a single Java class from which many Java object instances may be created.

I've set up a data binding between a Label in an FXML file and an IntegerProperty in the associated controller.

I've been looking at some blogs and other stackoverflow questions, and I'm not seeing a direct answer to my question.

I just don't want to have all of my code for my login, menubar, and main content in the same file. This is an image of what i am working on: Use FXML as components

How do I access a UI element from another controller class in JavaFX?

阅读更多关于 How do I access a UI element from another controller class in JavaFX?

I have a JavaFX / Java 8 application written with NetBeans 8 (no SceneBuilder ). My application has a main window that has its own FXML file (primary.fxml) and its own controller class (FXMLPrimaryController.java). One of the items in the FXML is a TextArea . Some of the methods in FXMLPrimaryController.java are about appending to that TextArea . This application now spawns a second window (another "stage") with its own FXML (second.fxml) and its own controller class (FXMLsecondController.java). Within the second controller class, how can I access the TextArea in the primary? Here's a sample

I want to change the styling of a button, most of the threads here and the articles on the internet show how to do it using Java code, which I don't see it as a real good solution, is there any way for example to set a button with some text and an image inside it all by using FXML only (no Css) ? jewelsea Solution using only fxml As tarrsalah points out, css is the recommended way of doing this, though you can also do it in fxml if you prefer: <?import java.lang.*?> <?import java.util.*?> <?import javafx.scene.control.*?> <?import javafx.scene.image.*?> <?import javafx.scene.layout.*?> <
