Javafxでスクロールペインの内容をどのように翻訳するのですか？

Question

こんにちは現在、特定のユーザー操作に応じて、スクロールペインのコンテンツの表示を移動させています。アプリケーションでは、同じサイズの画面と同じサイズの3つの画像ビューを含むgridPaneがあります。しかし、スクロールペイン（またはその内容を私が試した）をsetTranslateX（）で翻訳し、パラメータを画面の幅に設定しようとすると、ズームやパンに関するすべての機能がうまく動作します。スクロールペインの場合は内容または空白の画面が表示されます。あなたが "WorldProvincialMap-v1.01.png"の画像を置き換えても同じように動作するはずです。コードはエラーを生成せず、目的の結果を達成できません。

Answer 1

私はmapScroll.setHvalue（）を使用しなければならなかった内容を翻訳するために、パラメータとしてdoubleを使用します（ピクセルは移動しません）。
