我想弄清楚为什么我的文字没有在这里显示。我认为它不是白色的，根本不会出现在黑色背景上。所以，我想弄清楚为什么背景是黑色的，但没有显示文本。
我正在使用 JavaFX 12。
如何将字母涂成白色？
public class MCVE extends Application {
private static Stage gameStage = new Stage();
@Override
public void start(Stage primaryStage) {
gameStage.setScene(new Scene(createScreen(), 1280.0, 800.0));
// adjust window settings.
gameStage.setTitle("my game");
gameStage.setResizable(false);
gameStage.show();
}
private Pane createScreen() {
Text welcome = new Text("Welcome,");
welcome.setFont(new Font("Old_Style", 22.0));
welcome.setStyle("-fx-text-fill: whitesmoke");
Text toMyGame = new Text(" to my game.");
toMyGame.setFont(new Font("System", 14.0));
toMyGame.setStyle("-fx-text-fill: whitesmoke");
TextFlow tf = createTextFlow();
ObservableList list = tf.getChildren();
list.addAll(welcome, toMyGame);
return tf;
}
private TextFlow createTextFlow() {
String style = "-fx-background-color: black;";
style += " -fx-text-fill: whitesmoke;";
TextFlow tf = new TextFlow();
tf.setStyle(style);
return tf;
}
}
