问题 I need to access the WhatsApp Web from a JavaFX application I'm not getting. When the page opens I get a message to use another browser. I have tried to change the UserAgent but it does not work. Code: WebEngine eng = webView.getEngine(); eng.load("https://web.whatsapp.com/"); eng.setJavaScriptEnabled(true); eng.setUserAgent("Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/68.0.3440.106 Safari/537.36"); How can I solve this? 回答1: I was unable to

问题 I am looking for an alternative of Swing InputVerifier to JavaFX TextField. The Swing InputVerifier will prevent input that does verify. Consider the following Swing JTextField code: InputVerifier iv = new InputVerifier() { /* (non-Javadoc) * @see javax.swing.InputVerifier#verify(javax.swing.JComponent) */ @Override public boolean verify(JComponent input) { JTextField tf = (JTextField) input; if (!myRegExTool.matches(tf.getText())) { return false; } return true; } }; jinstance

问题 I'm trying to run a program using JavaFX. If I was using Swing, I would have one class started by the main method, and have it build the GUI class. That would give me 2 threads, normal thread for an application, and the EventQueue. That would prevent blocking the UI work. So, I tried to have the class created in the static main method construct the Application class, and then launch it. I got a RuntimeException because the program calling the launch method was not a subclass of Application.

问题 So i am trying to create an application that has values on a chart, which shows normally. However i am also trying to add a mouse event that is called when i click on a particular bar of the bar graph. More specifically it updates a status bar with some more detail pulled from the database. Group root = new Group(); String[] years = {"Opened", "Closed", "Still Opened"}; CategoryAxis xAxis = new CategoryAxis(); xAxis.setCategories(FXCollections.observableArrayList(years)); NumberAxis yAxis =

问题 I have been trying to create an image object like this: Image img = new Image("images/jack.png"); or Image img = new Image("jack.png"); or /jack.png or /images/jack.png etc. I have looked up the working directory using System.getProperty("user.dir") and it is indeed where I put my image file. When I use file: prefix, it does work, like so: Image img = new Image("file:images/jack.png"); However, it is also supposed to work without using it. In the textbook it is done without file: . I've seen

问题 I have implemented a drag-and-drop function to my game, but so far I can only "drop" to hard-coded locations. As shown here: What I would like is for either: When the ships is dropped its x,y values (in relation to the GridPane) are saved, or The cell that the ship is dropped to is saved. My setOnDragDropped event is handled here: //Drag dropped draws the image to the receiving node target.setOnDragDropped(new EventHandler<DragEvent>() { public void handle(DragEvent event) { //Data dropped /
