    <p>I want to implement a simple popup control, which should be styleable with CSS. It's all working fine the only question is how to add content (a Node in JavaFX) to it?</p> <p>The <code>PopupWindow.getContent()</code> method is deprecated in JavaFX 2.2.6 and not working with CSS, I am able to see the content but the CSS-selector will not work then.</p> <p>So what is the best solution to add content myself, should I implement my own Skin class for that purpose or is there a simple way to just make it work?</p> <p>I have prepared a simple use case:</p> <pre><code>import javafx.scene.control.Label; import javafx.scene.control.PopupControl; import javafx.scene.layout.StackPane; import javafx.scene.shape.Rectangle; public class PopupTest extends PopupControl { public PopupTest() { getStyleClass().add("popup"); // not working!? StackPane pane = new StackPane(); pane.getStyleClass().add("pane"); Rectangle rectangle = new Rectangle(250, 250); rectangle.getStyleClass().add("rect"); Label text = new Label("popup test"); text.getStyleClass().add("text"); pane.getChildren().addAll(rectangle, text); // how to display to pane when the popup is shown? getContent().addAll(pane); } } </code></pre> <p>For completeness here are my MainApplication and CSS file:</p> <pre><code>import javafx.application.Application; import javafx.event.ActionEvent; import javafx.event.EventHandler; import javafx.scene.Group; import javafx.scene.Scene; import javafx.scene.control.Button; import javafx.stage.Stage; public class MainApplication extends Application { @Override public void start(Stage stage) throws Exception { Group root = new Group(); final Scene scene = new Scene(root); scene.getStylesheets().add(MainApplication.class.getResource("style.css").toExternalForm()); final Button button = new Button("show popup"); button.setOnAction(new EventHandler&lt;ActionEvent&gt;() { @Override public void handle(ActionEvent event) { PopupTest popup = new PopupTest(); popup.show(scene.getWindow()); } }); root.getChildren().add(button); stage.setScene(scene); stage.show(); } public static void main(String[] args) { launch(args); } } </code></pre> <p>style.css:</p> <pre><code>.popup { -fx-font-size: 24px; } .popup .rect { -fx-fill: green; } .popup .text { -fx-text-fill: white; -fx-font-weight: bold; } </code></pre> <p>The ".popup" selector is not working here, if I set it to the "pane" it will style the popup window so the css is correct: <code>pane.getStyleClass().add("popup"); // working with this "fix"</code>.</p>

    2. COI tried that one before, but essentially the Popup class is the same as PopupWindow, and PopupControl (also extends PopupWindow) also implements the javafx.scene.control.Skinnable interface which should make it style-able via CSS.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
