问题 I am on Windows 8. I have a JavaFX app that creates a simple window with a webview control and loads the local file "test.html". "test.html" contains javascript (a simple "alert("hello");<(script>"). However, the javascript is ignored. What rendering engine does webview in JavaFX use? I have Firefox and IE installed. The latter executes JS contained in local files only if the users accepts to do so. So my assumption is that webview uses IE due to some configuration of my OS. Is this possible?

问题 I'm trying to configure the root node of my TreeView in FXML: <TreeView fx:id="treeView" prefHeight="-1.0" prefWidth="-1.0" VBox.vgrow="ALWAYS"> <TreeItem expanded="false" value="Root" fx:id="rootItem" graphic="/icons/icon_folder.png" /> </TreeView> There is a property called graphic which takes a Node , and not a String as I have supplied above. How do I give it a node in FXML that would represent the image stored in my resource at icons/icon_folder.png? In Java, I can do the following:

问题 While learning the javafx.animation API, I tried the following code, which simply draws a rectangle at (100,100) and translates it to (200,200) in 2 seconds. import javafx.animation.TranslateTransition; import javafx.application.Application; import javafx.scene.Group; import javafx.scene.Scene; import javafx.scene.layout.VBox; import javafx.scene.paint.Color; import javafx.scene.shape.Rectangle; import javafx.stage.Stage; import javafx.util.Duration; import javafx.event.ActionEvent; import

问题 There are no null fields in the Media block that launch the MediaPlayer I have researched this extensively and have found nothing to explain this error. I am building a Java Swing application for a class project and am attempting to use the JFX panel and media player to host and play several mp4 videos. I have successfully got it working one time through however when I come back to the window again I run into the error. java.lang.NullPointerException at com.sun.media.jfxmediaimpl.platform

问题 In a game I have a GridPane displaying the Tiles of the world in square cells. The player can, using the keyboard, move what is displayed by a column\row. The approaches I've thought of are: Having the GridPane change programmatically the displayed tiles by moving everything by x steps on player input. Wrapping the GridPane in a ScrollPane and tying the ScrollPane's scroll to Keyboard input. My question is, assuming that things that are off-sight but on the same map are always loaded, what

问题 Starting from this question JavaFX LineChart Hover Values I modified the Gist in the first answer https://gist.github.com/jewelsea/4681797 into this public class TestCharts extends Application { ObservableList<XYChart.Data<Integer, Integer>> _serie; @SuppressWarnings("unchecked") @Override public void start(Stage stage) { LineChart lineChart = new LineChart(new NumberAxis(), new NumberAxis()); XYChart.Series serie = new XYChart.Series( "Test", getTestValues() ); lineChart.getData().add(serie)

问题 I'm developing gant chart with JavaFx. My main content is placed inside of ScrollPane. I have zoom option which is changing content width. This is performance related to content size: zoom: x1 - 2880px // smooth scrolling x2 - 5760px // smooth scrolling x3 - 8640px // smooth scrolling x4 - 11520px // bad/jumps x5 - 14410px // very bad/ not smooth at all x6 - ... // :-/ Is it possible to fix it some how?
