JavaFX 8アプリケーションに画像をロードするこのcssファイルがあります:

#pill-left {  
    -fx-padding: 5;  
     -fx-border-image-source: url("/com/dx57dc/images/left-btn.png");

イメージは、Java パッケージ com.dx57dc.images にあります。

Java 7_25 ではこのコードは期待どおりに動作しますが、JavaFX 8 b99 では次のエラーが発生します。

Java 8でcssから画像をロードする適切な方法は何ですか?

1 に答える 1

私はこのような構造を持っています:

view
|--css
|   |- style.css
|
|--img
    |- image.png

そして、次のように画像を使用します。

 -fx-background-image: url("../img/image.png");

だから、もし

/com/dx57dc/images/

css ファイルに対してすでに相対的な場合は、先行するドット ["./com/dx57dc/images/"] を試してください。それ以外の場合は、(複数の) "../" を使用して共有の親フォルダーに戻ります
