javafx-8

问题 I am developing a JavaFX 8 application that runs cross-platform on Windows/OSX/Ubuntu via JWrapper. Right now I am using stage.getIcons().add(..) to set the stage icon to a 256x256 PNG bundled with the application. This works on Windows, however on Ubuntu, the dock icon remains the Oracle/Java default icon, as shown below. Is there some third party library, or some technique I can use to get my own icon and tooltip/title to display for the Ubuntu dock icon? 回答1: Ubuntu is a bit different: You

问题 The following example and explanations are quite long, so here is the gist of my question: how to deal with scalac's name-mangling of private fields when using a framework which insists on performing field injection (on fields which really should stay private)? I am writing an application in Scala, using ScalaFX/JavaFX and FXML. When you use FXML to define your views in JavaFX, objects defined in FXML (such as buttons and text fields) are injected into the controller by : adding an fx:id

问题 I need to update my GUI based on client input. Calling my controller class method, from the background task works. But it can't update the GUI, because it is not the JavaFX application thread..please help. I tried many of the related Q & A, but I am still confused. Should I use Platform. runLater or Task ? Here's my class where I create an instance of controller class public class FactoryClass { public static Controller_Gui1 createGUI() { FXMLLoader fxLoader = new FXMLLoader(); fxLoader

问题 I want to rotate an object round a custom pivot, which is its point, so I have such code: private final EventHandler<MouseEvent> mouseEventHandler = new EventHandler<MouseEvent>() { @Override public void handle(MouseEvent mouseEvent) { if (mouseEvent.getEventType() == MouseEvent.MOUSE_PRESSED) { dragStartX = mouseEvent.getSceneX(); dragStartY = mouseEvent.getSceneY(); mousePosX = mouseEvent.getSceneX(); mousePosY = mouseEvent.getSceneY(); mouseOldX = mouseEvent.getSceneX(); mouseOldY =

问题 I need help creating a null -safe BooleanBinding . It has to be null -safe since I can not provide default values for all attributes in the model (one reason: the model contains enumerations). My first approach has been as follows: executeButtonDisabled.bind(missionProperty().isNotNull().and(missionProperty().get().statusProperty().isNotEqualTo(MissionStatus.CREATED))); final BooleanBinding isNotExecutingBinding = missionProperty().isNotNull().and(missionProperty().get().statusProperty()
