adding css file to stylesheets in javafx

Question

Language: JavaFX

IDE: Netbeans

Problem: I\'m trying to add a css file to the stylesheet, but the first line of the following code always generates a Nu

Answer 1

All of the answers are missing one very important part and that's '/' before the name of the css file:

Folder structure:

src
  resources
    stylesheet.css

Load it like this, notice the starting slash before css file:

scene.getStylesheets().add(getClass().getResource("/stylesheet.css").toExternalForm())

Answer 2

I made a small login example and this is how i link my styleshet.css

@Override
public void start(Stage stage) throws Exception {
    Parent root = FXMLLoader.load(getClass().getResource("LoginUI.fxml"));


    Scene scene = new Scene(root);

    scene.getStylesheets().add(JavaFXLogin.class.getResource("stylesheet.css").toExternalForm());

    stage.setScene(scene);
    stage.show();

}

You can use this code line to link your css file. but the css file should be in your package.

scene.getStylesheets().add(JavaFXLogin.class.getResource("stylesheet.css").toExternalForm());

Answer 3

Try putting '@' the name of the file. It worked for me.

ex: '@main.css'

Answer 4

I think your're missing the slashes which causes that the CSS file can't be found. Try to correct your path reference.

For example:

-root
--app/Main.java
--assets/double_slider.css

would be:

String css = this.getClass().getResource("/assets/double_slider.css").toExternalForm();

Answer 5

I had the same problem (in NetBeans 8). I found a solution here : https://blog.idrsolutions.com/2014/04/use-external-css-files-javafx/

My resource file spreadsheet.css was here :

MyApp
-resources
--spreadsheet.css
-source packages
--fr.ccc.myapp.view
---mainView.java
---FXMLMain.fxml

In mainView.java :

File f = new File("resources/spreadsheet.css");
spreadsheet.getStylesheets().add("file:///" + f.getAbsolutePath().replace("\\", "/"));

Hope this helps.

Answer 6

scene.getStylesheets().add("file:///home/fullpathname/file.css");

or

scene.getStylesheets().add("file:/home/fullpathname/file.css");

but after:

Run / Clean and Build Project

worked for me
