プログラマも３人目の登場です。この人のプログラムは、前回までに紹介した２人よりも単純で 素直だと最初は思っていました。「上手ではないが、とんでもない書き方はしてないよ。連中の中 では一番まともなのでは。」とか最初は評価していました。しかし、開発が進むに連れて、先輩の 「模範プログラム」に影響されてか、はたまた指導によってかは知るよしもありませんが、しだい に変な書き方になってきたのです。本当に怖いですね。
Ｘウィンドウを使ったソフトウェアでは、会話的操作が多いため、ウィンドウ上にボタンなどを きれいに配置し、マウスだけで複雑な操作ができるようにします。今回のプログラムは、そういう 部分のウィンドの初期化です。（リスト１３−１）
