今日は、DOSコマンドを調べていました。

動画の作成の為ですけど、途中で…

以前からの課題、ウインドウの巻き上げを調べて羽目になってしまった！

成果

本体を作る

　大体できた（makiage.py）

方針！

方法１　グローバルフック　タイトルバーのシステムメニューにハックして追加する

方法２　グローバルフック

How can I paint an image in the caption bar?

※問題点

WPFでは、大丈夫なのか？

そんなこんなもあり（時間もあり）

タイトルバーには、自前でアイコンを表示する事にした

（これが安全で簡単）その検証が、（mainPin.py）

である。

マウスを動かすと小さなウインドウが追従する

これを利用して、以下を実現！

全てのウインドウにこの小さなウインドウ（アイコンを）付ける

（最小化アイコンの左側）

これをクリックすると巻き上げするというやり方だ！

どうかな～な！

でも、これが一番だと思ってやりますね
