问题 Is there any way of getting the Stage/Window object of an FXML loaded file from the associated class controller? Particularly, I have a controller for a modal window and I need the Stage to close it. 回答1: I could not find an elegant solution to the problem. But I found these two alternatives: Getting the window reference from a Node in the Scene @FXML private Button closeButton ; public void handleCloseButton() { Scene scene = closeButton.getScene(); if (scene != null) { Window window = scene

问题 I am working with a group which is looking to target a graphics renderer in Java. At the moment I am trying to figure out whether targeting java.awt.Graphics2D will be forward compatible. Namely, can other libraries like JavaFX display renders from a Graphics2D instance? Is there interoperability between java.awt.Graphics2D and javafx.scene.canvas.GraphicsContext ? Or, if not between Graphics2D and GraphicsContext directly, is there any means of displaying a Graphics2D render in a JavaFX

问题 I've got a MenuBar that is setup as follows in FXML: <MenuBar VBox.vgrow="NEVER"> <menus> <Menu mnemonicParsing="true" text="_File"> <items> <MenuItem mnemonicParsing="true" text="_New Project"/> <MenuItem mnemonicParsing="true" text="_Open…"/> <MenuItem mnemonicParsing="false" text="Quit"/> </items> </Menu> </menus> </MenuBar> This produces a menu as follows: I've successfully styled the MenuBar and the Menu File with the following CSS: .menu-bar { /* The menu bar itself */ } .menu { /* The

问题 I have to create an application in which minimize and maximize button will be disabled. I have used "StageStyle.UNDECORATED" with which the application will not be movable or draggable anymore, so I am searching for any other alternative to make my application. Do anyone having solution for this? 回答1: To achieve the window to be undecorated but still movable/dragable you have to handle the appropriate MouseEvent on any node of your choice. Example: import javafx.application.Application;

问题 In JavaFX, if I have a scene with 2 VBox elements and each VBox has multiple Label in it. If I set the top VBox to invisible , why does the bottom VBox not move up the scene where the top VBox was ? The VBox is invisible but I would expect the other objects to move into its place. I am using FXML to load my controls. 回答1: Node.setVisible(boolean) just toggles the visibility state of a Node . To exclude a Node from its parents layout calculations you additionally have to set its managed state,

问题 I'm trying to change the color of bar in ProgressBar with pBar.setStyle("-fx-accent: green"); but I have encountered a problem: that doesn't seem to work right for me! (Or I just don't understand something) here is the code: public class JavaFXApplication36 extends Application { @Override public void start(Stage primaryStage) { AnchorPane root = new AnchorPane(); ProgressBar pbRed = new ProgressBar(0.4); ProgressBar pbGreen = new ProgressBar(0.6); pbRed.setLayoutY(10); pbGreen.setLayoutY(30);

问题 I would like to know if it was possible to detect the double-click in JavaFX 2 ? and how ? I would like to make different event between a click and a double click. Thanks 回答1: Yes you can detect single, double even multiple clicks: myNode.setOnMouseClicked(new EventHandler<MouseEvent>() { @Override public void handle(MouseEvent mouseEvent) { if(mouseEvent.getButton().equals(MouseButton.PRIMARY)){ if(mouseEvent.getClickCount() == 2){ System.out.println("Double clicked"); } } } }); MouseButton

问题 I can't seem to find any material on the subject. To give a more concrete example, let's say I want to create a simple component that combines a checkbox and a label. Then, populate a ListView with instances of this custom component. UPDATE: see my answer for complete code UPDATE 2: For an up-to-date tutorial, please, consult the official documentation. There was a lot of new stuff that was added in 2.2. Finally, the Introduction to FXML covers pretty much everything you need to know about

问题 I have zip-compressed file, which contains a set of html pages. I need to load html-pages from it. I need to redefine the mechanism of resolve of links. It is possible using WebView javafx? 回答1: If I understand well your question. I'm guessing that you need to open html files. I extracted the next code from javafx 2 tutorial from Oracle WebView browser = new WebView(); WebEngine webEngine = browser.getEngine(); webEngine.load("http://mySite.com"); The load function takes a regular URL, so you
