问题 Is there a way to remove the blue frame from input filed? 回答1: The blue border you are showing is the focus border. To remove it entirely, use something like textField.setStyle("-fx-focus-color: -fx-control-inner-background ; -fx-faint-focus-color: -fx-control-inner-background ;"); or in an external css file .text-field { -fx-focus-color: -fx-control-inner-background ; -fx-faint-focus-color: -fx-control-inner-background ; } To make it the same as the unfocused text field, use .text-field

问题 Consider this code: Thread.setDefaultUncaughtExceptionHandler((Thread t, Throwable e) -> { System.out.println("An exception occurred!"); }); // set the exception handler for the JavaFX application thread Thread.currentThread().setUncaughtExceptionHandler((Thread t, Throwable e) -> { System.out.println("An exception occurred!"); }); Task<?> task = new Task() { @Override public Void call() throws Exception { throw new RuntimeException("foobar"); }; }; new Thread(task).start(); If we run the

问题 I'd like to use a (JavaFX) TabPane to display the content of 20 different tabs. This works fine with the standard TabPane, however, when the pane hits a certain amount of tabs, a button / ComboBox can be clicked to click on one of the tabs not seen. I'm designing a feature that will be used on a touchscreen, so this is not ideal. I think it'd be more intuitive to have two separate rows of tabs. How can I add two rows of tabs to a TabPane, or, what can be done to achieve a similar effect?

问题 I'm trying to resize a canvas in Javafx. I am using scene builder and fxml. So far, when the user clicks on the canvas the canvas turns black, and when I resize the screen and click on the canvas only the original size of the canvas turns black (canvas is not being resized). I'm not sure how to solve this. Any ideas or solutions would help alot. Code: Controller: public class MainFXMLController implements Initializable { @FXML private Canvas mainCanvas; @FXML public GraphicsContext gc; public

问题 It seems that in FXML if you don't specify a ID (CSS) then the fx:id value is used by default. My previous understanding was the two were completely disjoint, ID for CSS and only CSS. fx:id for @FXML bindings in the controller. This can be demonstrated with a small test - three buttons, first with ID, second with FX:ID, third with both types of ID. <VBox maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="400.0" prefWidth="600.0" xmlns="http:/

问题 I have this simple example with JavaFX tabs: public class test extends Application { private BorderPane root; // Navigation Utilization private ActionTabs actiontabs; @Override public void start(Stage primaryStage) { // Set Main Window Label primaryStage.setTitle("Desktop Client"); Image iv = new Image(getClass().getResource("/images/internet-icon.png").toExternalForm()); primaryStage.getIcons().add(iv); root = new BorderPane(); root.setLeft(getLeftHBox(primaryStage, root)); Scene scene = new
