Make sure to provide the complete path starting from the root of the classpath.
The way to resolve the path differs depending on whether you are accessing a CSS URL resource within a style sheet or directly in an inline style.
Refer to the URI information in the CSS reference for detailed guidance and examples that can help clarify any confusion you may have. According to the CSS URL resolution documentation:
- If the address does not contain a
scheme: part, then it is treated as just the path.
- A leading
/ at the beginning indicates that the path is relative to the classpath's root.
- In case the style is included in a stylesheet without a leading
/, the path should be relative to the base URI of the stylesheet.
- For styles written directly in an inline format, the path is always relative to the classpath's root (regardless of the presence of a leading
/).
For instance,
-fx-background-image: url('Background.quiz.jpg');
When utilized within a CSS file, this will search for the image alongside the stylesheet within the classpath.
However, when used in an inline style, it will look for the image at the classpath's root level.
To ensure correct resolution for the inline style URL, provide the full path starting from the classpath's root where the image resides.
If your application is packaged as a jar file, and the image is located in a place like image/Background2.quiz.jpg within the jar, then the appropriate URL to use in an inline style would be:
settingsGrid.setStyle("-fx-background-image: url('image/Background2.quiz.jpg')");
