I have strange problems with JavaFX that look a lot like a bug. I want to do the following:
- Entering fullscren when starting my application
- Press escape to exit the application (not fullscreen, the entire application)
So far, I have the following code:
public class AppTest extends Application {
public static void main(String[] args) {
launch(args);
}
public void start(Stage stage) {
stage.setOnCloseRequest(t -> {
Platform.exit();
System.exit(0);
});
stage.setFullScreenExitHint("Press ESCAPE to exit");
stage.setFullScreenExitKeyCombination(KeyCombination.NO_MATCH);
stage.setFullScreen(true);
Rectangle2D screenBounds = Screen.getPrimary().getBounds();
stage.setX(screenBounds.getMinX());
stage.setY(screenBounds.getMinY());
double screenWidth = screenBounds.getWidth();
double screenHeight = screenBounds.getHeight();
stage.setWidth(screenWidth);
stage.setHeight(screenHeight);
Group root = new Group();
Scene scene = new Scene(root);
stage.setScene(scene);
scene.setOnKeyTyped(event -> {
if(event.getCode() == KeyCode.ESCAPE) {
stage.close();
}
});
Canvas canvas = new Canvas(screenWidth, screenHeight);
root.getChildren().add(canvas);
GraphicsContext gc = canvas.getGraphicsContext2D();
gc.setFill(Color.BLUE);
gc.fillRect(0,0, screenWidth, screenHeight);
stage.show();
}
}
I'm on macOS.
In general it goes fullscreen. I'm saying in general because the real version of this code doesn't always. Sometimes, it is just a maximized window.
Then, when pressing escape, I get a maximized window instead of exiting the application.
How can I fix that?
