カスタム描画、所有者描画、およびサブクラス化については既に知っています。これまでのところ、私の選択はカスタム描画です。サブクラス化は私の 2 番目の選択肢ですが、作成するボタンの量は膨大です。誰か他の提案があれば、コメントしてください。とにかく、win32のどこにも直接の答えがないので、カスタム描画のコードを投稿します。

最初の画像は何も選択されていないとき、2 番目の画像は最初のボタンが選択されて押されたとき、最後の画像は 2 番目のボタンが押されてマウスがその上にあるときを示しています (輝度の増加に注意してください - カットム ハイライト)。これを行うには、NM_CUSTOMDRAW メッセージをキャッチし、自分でボタンをペイントする必要があります。そして、これがあなたのやり方です。また、グラデーション ブラシ機能といくつかのコメントを追加しました。
