问题 with the ScheneBuilder I defined the controller class of my fxml, the code genereted inside my AnchorPane tag is: fx:controller="demo.SplashController" now I would like if I had args in the main, to load a new version of the controller, using the appropriate construct. I try this code in the Application.start: FXMLLoader loader = new FXMLLoader(getClass().getResource("page.fxml")); PageController controller; if(!dir.equals("")){ //attribute coming from args controller = new PageController(dir

问题 ObjectPropertyBase skips value invalidation when newValue == oldValue : /** * {@inheritDoc} */ @Override public void set(T newValue) { if (isBound()) { throw new java.lang.RuntimeException((getBean() != null && getName() != null ? getBean().getClass().getSimpleName() + "." + getName() + " : ": "") + "A bound value cannot be set."); } if (value != newValue) { value = newValue; markInvalid(); } } Problem: markInvalid() and value are private , therefore I cannot override set(newValue) properly.

问题 I have a java desktop app using Swing which I rewrote in JavaFX using SceneBuilder. The Swing app works fine on all users machines (35 Machine). After rewriting the app in JavaFX, on one specific machine the app won't start and gives the below error message. I couldn't figure out the issue. I appreciate if someone can give any help. Thank you. Exception in Application start method java.lang.reflect.InvocationTargetException at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0

问题 I am putting together an image gallery that displays a preview of the image. For most of the images this is no problem, only when the image is an animated gif the image is animated as well, which in this case is not necessary. What I would like to do for an animated gif is to just display one frame of the animation. While searching for a solution I have come across this. GifDecoder d = new GifDecoder(); d.read( filename); WritableImage wimg = null; Image img = SwingFXUtils.toFXImage(d

问题 I want to be able to choose the layer that the Nodes appear and change it throughout the course of the program. I know that the last added Nodes appear on the top of the previous one. In swing, I use JLayeredPane and its method setLayout(JComponent, integer). The higher the int, the higher level the component appears on screen. Is there something similar? Thank you 回答1: I think you can play with the z-order indices of child nodes by combinations of Node node = pane.getChildren().get(index);
