问题 I have created a JavaFX application (running on Ubuntu, Java(TM) SE Runtime Environment (build 1.8.0_131-b11)) and have made a simple test application: public class DelayedSceneApplication extends Application { @Override public void start(Stage primaryStage) throws Exception { primaryStage.setTitle("Test"); primaryStage.setResizable(false); // Root. BorderPane root = new BorderPane(); Scene scene = new Scene(root); primaryStage.setScene(scene); // Buttons box. HBox buttonBox = new HBox();

问题 I searched but could not find anything close to the problem that I am having with Fx. I am using Java Fx/JDK 8 and having problems with resizing the scene(s). The below code below loads only one screen at a time in scene graph, and switches between the screens. The problem is when I resize the stage. The scene is not being resized with the stage. Nothing fancy in FXML files only anchor pane and a few components.Thanks in advance. public class ScreensFramework extends Application { static

问题 Consider I have a sample JavaFX application which updates its UI with an image read from the application's JAR, and does so in a delayed manner (i.e. the image is painted after the UI is shown): import javafx.application.Application; import javafx.application.Platform; import javafx.embed.swing.SwingFXUtils; import javafx.scene.Node; import javafx.scene.Scene; import javafx.scene.control.Label; import javafx.scene.image.ImageView; import javafx.scene.layout.StackPane; import javafx.stage

问题 I have a window that has three different line charts in it. I am trying to set the color of each line chart series individually. Right now I have a css file that has something like this: .default-color0.chart-series-line { -fx-stroke: blue } .default-color1.chart-series-line { -fx-stroke: black } What this does is set the colors of series in each chart. For example, if I have a line chart that has two series, one would be blue, the other would be black. But with this setting, all three charts

问题 Do you know how to wait for the user's input in a for loop? I don't mean the showAndWait() method, because I am not opening a new dialogue stage for the user.
