How can i select TitledPane`s title in Java Code, without CSS?

I made TitledPane and want to make the title`s font weight is bold.

So i tried like this.

TitledPane Rootpane = new TitledPane();
Rootpane.setText("Options");
Rootpane.setStyle("-fx-background-color: #eeeeee; -fx-text-fill: #1b75bc; -fx-font-weight: bold;");

and the title became bold but the other buttons which are located in TitledPane also became bold...

I just want to make Title is bold without CSS file.

So how can i select the title in Java Code?

And i tried like this

Rootpane.lookup(".titled-pane > .title").setStyle("-fx-font-weight: bold;");

But the result was

Exception in thread "main" java.lang.NullPointerException

Samuel Philipp :

You should call the lookup() after the node was added to the stage and after Stage.show(). For example like this:

@Override
public void start(Stage primaryStage) {
    TitledPane root = new TitledPane();
    root.setText("Options");
    primaryStage.setScene(new Scene(root, 200, 100));
    primaryStage.show();

    root.lookup(".titled-pane > .title > .text").setStyle("-fx-font-weight: bold;");
}

As you can see you should also use .titled-pane > .title > .text to get the actual text label (docs).
