问题 Background Using JavaFX, I render a TableView and a Button side by side. The Table contains a number of entries which are more then the Table size. Hence TableView automatically shows a scrollbar for scrolling down. The Problem I want to scroll down the table by using the button. So pressing the button, scroll down the table by 5 entries. I found the scrollTo() method, which would be sufficient for the task, but I need an index to scroll to. Which I do not have, as far as I understand there

问题 Is there a way to identify the type of the clicked element in webView (like Textbox/Radio/Button etc) using the webEngine.getDocument() ? Suppose I click on a textfield, I can get the x,y coordinates of the clicked position. Is it possible to identify the element present in that particular location? Something like the document.elementFromPoint() method in Javascript. I can do it using Jquery/Javascript. But since we have access to Document object and its elements, is there a way to identify

问题 This question is a follow-up question to Custom object drag-and-drop from FX to Swing. I'm working on a plugin for a Swing application that uses JavaFX for some graphical user interfaces. We added drag-and-drop functionality to improve the user experience. First, we were using an external JavaFX window ( Stage ) for our Scene , now we want to embed it directly into the Swing application via a JFXPanel . Now, the strange thing is, that it seems to make a big difference for drag-and-drop

问题 I'm looking for form validator similar to these examples: or Is this custom JavaFX component or this can be done using standard JavaFX? Is there any example how I can create form validator similar to these? 回答1: Just to give you a kick start, here is a small example with using ContextMenu. May be ContextMenu is not an ideal Control for this scenario and you are free to replace it with Label, Text etc. Keep the TextField and Label inside a HBox (with Label being hidden initially) and the HBox

问题 I am testing using Spring Boot with JavaFX (Based on some excellent YouTube videos that explain this). To make it work with TestFX, I need to create the context like this: @Override public void init() throws Exception { SpringApplicationBuilder builder = new SpringApplicationBuilder(MyJavaFXApplication.class); builder.headless(false); // Needed for TestFX context = builder.run(getParameters().getRaw().stream().toArray(String[]::new)); FXMLLoader loader = new FXMLLoader(getClass().getResource(

问题 we are struggling on a problem with custom css for our application. Until now we used workaround to apply our custom css but keep modena style for the rest. StyleManager.getInstance().addUserAgentStylesheet(css); In 8u40 java update this behavior was however restricted and is no longer working. Setting stylesheets to all scenes separately is madness, setting custom stylesheet via Application.setUserAgentStylesheet(css); works but not as we intended - modena stylesheet is replaced by custom so

问题 I am making a JavaFX kiosk application that needs to take full control of the screen and disallow closing, minimising, and certain keypresses. I was wondering is there a way to make a JavaFX application run in full screen exclusive mode, if not are there any alternatives that could achieve the same goal. I have tried using: stage.setFullScreen(true); which does successfully make the application full screen, however the user can still exit the application or exit the full screen. 回答1: Handle
