While Drag and Drop in JavaFX has a common API for all the platforms (as the rest of the API, of course), its internal implementation is platform dependent, and it is quite different on Windows, Mac or Linux. But this shouldn’t be an issue when migrating from JavaFX 8 to JavaFX 11, though. The sample … Read more
I ran into the same problem; the following worked for me and helped me make sense of those blasted “Error invoking method.” and “Failed to launch JVM” dialogs: Find your .jar file It has the same name as your Project and it’s in your application’s installation directory under AppData\Local\{ApplicationTitle}\app (shortcut: type %appdata% into explorer); if … Read more
MenuButton uses Menu internally and has a similar API. In such way that MenuButton contains MenuItems list just like Menu. So I think you need to try to play with .menu, .menu-button and .menu-item CSS selectors in caspian.css. More specifically with .menu-item. EDIT: It seems you need to change the .context-menu too, because the popped … Read more
Using the JavafX JAR export option doesn’t work anymore in Intelij. You can export it as a regular jar with “Jar-From module with dependencies”. This will export a valid Jar, but in order to run it, you need to add your javaFx path and modules to your command. After you have the jar, the run … Read more
Here is some code I use to allow a Label to be dragged around in a Pane. I don’t notice any significant lag behind the mouse trail with it. // allow the label to be dragged around. final Delta dragDelta = new Delta(); label.setOnMousePressed(new EventHandler<MouseEvent>() { @Override public void handle(MouseEvent mouseEvent) { // record a … Read more
Use FXML as components by using a custom java class as fx:root and as fx:controller of your FXML file: http://docs.oracle.com/javafx/2/fxml_get_started/custom_control.htm To do so, you need to call in the constructor of your custom java class FXMLLoader which will load your FXML. The advantage is to change the way FXML load components. The classic way to … Read more
You can style your dialogs with your own css file, but for that you need to take into consideration that the dialog is in fact a new stage, with a new scene, and the root node is a DialogPane instance. So once you create some dialog instance: @Override public void start(Stage primaryStage) { Alert alert … Read more
For any node in your scene (for example, the root node; but any node you have injected with @FXML will do), do chooser.showOpenDialog(node.getScene().getWindow());
It is possible to use TextFlow container from JavaFX8. Then you can easily add differently styled Text nodes inside it. TextFlow flow = new TextFlow(); Text text1=new Text(“Some Text”); text1.setStyle(“-fx-font-weight: bold”); Text text2=new Text(“Some Text”); text2.setStyle(“-fx-font-weight: regular”); flow.getChildren().addAll(text1, text2); TextFlow container will automatically wrap content Text nodes.
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.PRIMARY is used to determine if the left (commonly) mouse button is triggered the event. Read the api of getClickCount() to conclude that there maybe multiple click … Read more
