JavaFX 8 - Add a graphic to a TitledPane on the right side

Question

I want to add a little icon to the title of a `TitledPane`. Therefore I set an empty title and add a `HBox` containing a `Label` and a `ImageView` as graphic. In this way the icon is shown close to the end of the text. I want it to be shown always next to the right border of the `TitledPane`. How can I do this? I also tried to use a `BorderPane` and add the `Label` to the center and the `ImageView` to the right, but the `BorderPane` doesn't get the maximum size of the TitledPane. So I tried to set MaxWidth to Max-Value, but this didn't help Does anybody know what to do? **EDIT: ** The "custom" control I created will be initialized within a method called in stage.setOnShown. ``` public class CustomTitledPane extends TitledPane { private Image alert; private Image registered; private Image deleted; private ImageView img; public CustomTitledPane(String titleText, Node node) { super(titleText, node); setAnimated(true); setCollapsible(true); img = new ImageView(); img.setFitHeight(10d); im…

Accepted Answer

Based on the code shown by the OP on his edited question, this code addresses the fact that the titled pane is created on a listener before the stage is shown, on a custom class.

```
@Override
public void start(Stage primaryStage) {

Scene scene = new Scene(new StackPane(), 300, 250);

primaryStage.setScene(scene);

primaryStage.setOnShown(e -> {
        CustomTitledPane customTitledPane = new CustomTitledPane("Title", new StackPane(new Label("Graphic to the Right")));
        scene.setRoot(customTitledPane);
        customTitledPane.applyCss();
        customTitledPane.layout();

// title region
        Node titleRegion=customTitledPane.lookup(".title");
        // padding
        Insets padding=((StackPane)titleRegion).getPadding();
        // image width
        double graphicWidth=customTitledPane.getGraphic().getLayoutBounds().getWidth();
        // arrow
        double arrowWidth=titleRegion.lookup(".arrow-button").getLayoutBounds().getWidth();
        // text
        double labelWidth=titleRegion.lookup(".text").getLayoutBounds().getWidth();

double nodesWidth = graphicWidth+padding.getLeft()+padding.getRight()+arrowWidth+labelWidth;

customTitledPane.graphicTextGapProperty().bind(customTitledPane.widthProperty().subtract(nodesWidth));
    });

primaryStage.show();

}

class CustomTitledPane extends TitledPane {

public CustomTitledPane(String titleText, Node node) {
        super(titleText, node);
        setAnimated(true);
        setCollapsible(true);
        ImageView img = new ImageView(new Image(getClass().getResource("unlock24.png").toExternalForm()));
        img.setFitHeight(10d);
        img.setPreserveRatio(true);
        img.setSmooth(true);
        setGraphic(img);
        setContentDisplay(ContentDisplay.RIGHT);
    }
}
```
