java - 更改控件的颜色 FX PopOver 标题

Question

想要更改设置为始终打开的控件 FX PopOver 标题的颜色。我想在 CSS 中执行此操作，我已经更改了背景颜色。我在 .popover 下尝试了几个不同的选项。

这是我最后尝试的 CSS 示例:

public class HelloPopOver extends Application {

    @Override
    public void start(Stage primaryStage) {


        //Build PopOver look and feel
        Label lblName = new Label("John Doe");
        Label lblStreet = new Label("123 Hello Street");
        Label lblCityStateZip = new Label("MadeUpCity, XX 55555");   
        VBox vBox = new VBox(lblName, lblStreet, lblCityStateZip);
        //Create PopOver and add look and feel
        PopOver popOver = new PopOver(vBox);

        // I always want to see my header
        popOver.setHeaderAlwaysVisible(true);

        Label label = new Label("Mouse mouse over me");
        label.setOnMouseEntered(mouseEvent -> {
            popOver.show(label);
            ((Parent)popOver.getSkin().getNode()).getStylesheets().add(getClass().getResource("Style.css").toExternalForm());
        });


        StackPane root = new StackPane();
        root.getChildren().add(label);

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

        primaryStage.setTitle("Hello World!");
        primaryStage.setScene(scene);
        primaryStage.show();
    }


    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        launch(args);
   }    
}

还有 CSS:

.popover > .border {
    -fx-stroke-width: 0.5;
    -fx-fill: rgba(200,200,200, 1);
    -fx-text-fill: red; /* This doesn't work, but is what I am looking for */
}
.popover > .label {
    -fx-text-fill: red; /* This doesn't work, but is what I am looking for */
 }

CSS 如何将标题颜色更改为红色？

Answer 1

我遇到了同样的问题，并通过查看 org.controlsfx.control 中的 popover.css 文件解决了这个问题。

这应该可以解决问题:

.popover > .content > .title > .text  {
    -fx-text-fill: red;
}
