问题 I'm trying out JavaFX-2 and one of the features is said to be that we can create event handler functions using Javascript in our FXML file. One thing that bugged me is I can't access the System class right away. It needs to be fully referenced, like "java.lang.System". That becomes ugly when we need a simple output on the console, I mean come on, "System.out.println" is ugly enough to get something printed. And, even though my FXML has all the <?import java.lang.*?> statements, apparently it

问题 I have a question. I want to change the color of a pane from another controller class. I am using this code: FXMLLoader loader = new FXMLLoader(getClass().getResource("/fxml/Menu.fxml")); try { Parent loaded = (Parent) loader.load(); } catch (IOException e) { e.printStackTrace(); } MenuController controller = (MenuController) loader.getController(); Platform.runLater(new Runnable() { @Override public void run() { Pane pane = controller.getRedPane(); pane.setBackground(new Background(new

问题 Good Day, I a working my way through the official JavaFX FXML tutorial (See source code here). However when I compile it using the Netbeans IDE I get the following error: Can anyone help me with this I'm running JDK 1.7 and JavaFX 2.0 init: Deleting: C:\Users\riash\Documents\Riaz\Personal\Java\Samples\FXMLExample\build\built-jar.properties deps-jar: Updating property file: C:\Users\riash\Documents\Riaz\Personal\Java\Samples\FXMLExample\build\built-jar.properties compile: Detected JavaFX Ant

问题 I'm writing some code where I interact (Change text) with FXML elements from the start method. However, I find that when I call the method from my controller class I get a NullPointerException. I've found that the issue has something to do with threads, but I have been able to get anything to work. I have included some sample code that generates the same problem. Main class: public class Main extends Application { Controller C = new Controller(); @Override public void start(Stage stage)

问题 I'm having a bit of trouble with the Text.setText() method. It is supposed to set the String name as it's value. The FXML code has the text: <Text fx:id="airlineName" strokeType="OUTSIDE" strokeWidth="0.0" text="Airline Name Goes Here" GridPane.rowIndex="1"> <font> <Font size="17.0" /> </font> </Text> Here is a fragment of the java code: @FXML Text airlineName; private void loadNewWindow(String resource, Button button) throws IOException { Stage stage = (Stage) button.getScene().getWindow();

问题 I am trying to make a TableView to programmatically resize its columns at startup in order to fit its content, to achieve this I found a method which works great when bound to a listener (for example #onKeyPressed ). But when i try to bind it to the showingProperty() of the primaryStage in order to call it without any user action it throws a NullPointerException on columnToFitMethod.invoke(tableView.getSkin(), column, -1) . In a previous post I exposed a similar problem, the difference was

问题 We have started to use the java FX with FXML for a desktop application. We need to load some combos with values from a local cache and we created a builder that instantiate the combo, fill it with values from cache and return it. We expect to have around 20 builders. I know most of java FX builders are deprecated because of this http://mail.openjdk.java.net/pipermail/openjfx-dev/2013-March/006725.html According to a FXML tutorial if the FXMLLoader cannot create an object of a class, it looks

问题 I want a Rectangle and a Label to align in the StackPane, however my code doesn't achieve the desired result: FXML: <fx:root type="HBox" xmlns:fx="http://javafx.com/fxml"> <StackPane fx:id="pane"> <children> <Rectangle fx:id="bubble" fill="#ffffff"></Rectangle> <Label fx:id="message" style="-fx-border-color:black; -fx-border-width: 1; -fx-border-style: solid;"></Label> </children> </StackPane> </fx:root> Controller: public class MessageBubble extends HBox implements Initializable { @FXML

问题 I'm trying to create javafx applet, using IntelliJ Idea. After building I get three files: .jar, .jnlp and .html. If I launch jar all works fine, but if I try to run app using jnlp or html it throws exception: java.lang.NullPointerException: Location is required. at javafx.fxml.FXMLLoader.loadImpl(Unknown Source) at javafx.fxml.FXMLLoader.loadImpl(Unknown Source) at javafx.fxml.FXMLLoader.loadImpl(Unknown Source) at javafx.fxml.FXMLLoader.loadImpl(Unknown Source) at javafx.fxml.FXMLLoader
