not working ccs style javafx -fx-strikethrough

Question

I want to make text strikethrough using CSS.

I use tag:

button.setStyle(\"-fx-strikethrough: true;\");

But this code is working, please

Answer 1

You need to use a CSS stylesheet to enable strikethrough on a button. Using a CSS stylesheet is usually preferable to using an inline CSS setStyle command anyway.

/** file: strikethrough.css (place in same directory as Strikeout) */
.button .text {
    -fx-strikethrough: true;
}

The CSS style sheet uses a CSS selector to select the text inside the button and apply a strikethrough style to it. Currently (as of Java 8), setStyle commands cannot use CSS selectors, so you must use a CSS stylesheet to achieve this functionality (or use inline lookups, which would not be advisable) - the style sheet is the best solution anyway.

See @icza's answer to understand why trying to set the -fx-strikethrough style directly on the button does not work.

Here is a sample application:

import javafx.application.Application;
import javafx.geometry.Insets;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

public class Strikeout extends Application {

    @Override 
    public void start(Stage stage) throws Exception {
        Button strikethrough = new Button("Strikethrough");
        strikethrough.getStylesheets().addAll(getClass().getResource(
                "strikethrough.css"
        ).toExternalForm());

        StackPane layout = new StackPane(
                strikethrough
        );
        layout.setPadding(new Insets(10));
        stage.setScene(new Scene(layout));

        stage.show();
    }

    public static void main(String[] args) {
        launch(args);
    }
}
