を使用して独自のチェス ゲームを作ろうとしているときに問題が発生しJLayeredPaneました。
私はこれまでに得ました：
(うまくいけばG6、どのブロックが選択されたかを示すラベルに緑の境界線が表示されます)
しかしSidePanel、パネルに 2 を追加してから、各ボードブロックを正確にカバーするラベルをChessBoard上に別のレイヤーにすると、そうではありません:
ご覧のとおり、ブロックを囲む緑色の境界線G2がオフになっています。
SidePanels を にChessBoard追加して最下層に追加し、そのサイズを 600x600 に設定してから、ブロックにChessBoard正確に収まるラベルである最上層と緑の境界線を追加すると、明らかに絞り込まれました。選択されたJLabel(および下のChessBoard四角 [黒または白])の周りに描画されます。SidePanelこれは、チェス盤の実際のサイズを 600x600 に縮小した s により、中心から外れて描画されます。現在は600-sp1.getWidth()xになります600-sp2.getHeight()。それを補うために最上位レイヤーの境界と優先サイズを設定しようとしましたが、役に立たないようです。どんな助けでも感謝します:

最初に私が使用した：
chessPieceLayer.setPreferredSize(boardSize);
chessPieceLayer.setBounds(0, 0, boardSize.width, boardSize.height);
それから私は試しました：
chessPieceLayer.setPreferredSize(new Dimension(600-sp1.getWidth(),600-sp2.getHeight()));
chessPieceLayer.setBounds(0+sp1.getWidth(), 0+sp2.getHeight(), 600-sp1.getWidth(), 600-sp2.getHeight());
しかし結果は変わらない
