C〓Tool Stripは四辺寄港フローティングツールバーを作ります。

フローティングツールバーの作成について、アリさんはいい文章を書いています。見てください。https://www.jb51.net/article/44272.htmアッ捷というツールストリップが浮動した後、上の方にしか停まらないです。これに基づいて、左/右/底の方に停まることを追加します。停泊条件はフロートフォームがメインフォームのエッジにぴったりくっついたり、越えたりすることです。実は阿捷が与えたコードはかなり詳しくなりました。ここでは主に書き換えたToolStripコードセグメントを提供します。3つのTool StripPanel
