你好我在JavaFx上有点新,我在oracle网站上获得了一个源代码,我想在JFXPanel中添加一个图标。如何在JFXPanel中插入一个图标。图标应该是位置。这是代码:
public class Test {
private static void initAndShowGUI() {
// This method is invoked on the EDT thread
JFrame frame = new JFrame("Swing and JavaFX");
final JFXPanel fxPanel = new JFXPanel();
JScrollPane pane = new JScrollPane(fxPanel,JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED,JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED);
frame.add(pane);
frame.setSize(300, 200);
frame.setVisible(true);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
Platform.runLater(new Runnable() {
@Override
public void run() {
initFX(fxPanel);
}
});
}
private static void initFX(JFXPanel fxPanel) {
// This method is invoked on the JavaFX thread
Scene scene = createScene();
fxPanel.setScene(scene);
}
private static Scene createScene() {
ImageIcon icon=new ImageIcon ( "icon/filter.jpg" );
// add icon here
return (scene);
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
@Override
public void run() {
initAndShowGUI();
}
});
}
}
答案 0 :(得分:2)
而不是ImageIcon
使用javafx.scene.image.Image
并将Image
添加到ImageView
,Node
,您可以添加到布局。
Image icon = new Image("stackoverflow5.png", 300, 300, false, false);
StackPane pane = new StackPane();
pane.getChildren().add(new ImageView(icon));
Scene scene = new Scene(pane, 300, 300);
来自Image
课程的关于文件位置的说明
// The image is located in default package of the classpath
Image image1 = new Image("/flower.png", true);
// The image is located in my.res package of the classpath
Image image2 = new Image("my/res/flower.png", 100, 150, false, false);
// The image is downloaded from the supplied URL through http protocol
Image image3 = new Image("http://sample.com/res/flower.png", 100, 0, false, false);
// The image is located in the current working directory
Image image4 = new Image("file:flower.png", 0, 100, false, false);
这是一个简单的例子
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
public class StackJavaFx extends Application {
@Override
public void start(Stage primaryStage) {
Image icon = new Image("stackoverflow5.png", 300, 300, false, false);
StackPane pane = new StackPane();
pane.getChildren().add(new ImageView(icon));
Scene scene = new Scene(pane, 300, 300);
primaryStage.setTitle("Hello World!");
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
