今日も見に来てくださってありがとうございます。こんな時期なのに、今日はなんと雪が降りましたね。
先日、tkinterの事前定義の色ってどんなのがあるのかなぁ、と、思って本家のホームページまでたどり着きました が、どんな色かわからないので、一覧を作ってみようと思いました。なんと、OS依存しない名称は760色、多いなぁ。20×38でちょっと作ってみよう。
出来上がりイメージは以下の通りです。
上記の画面を出力するためのスクリプトは以下の通りです。

前半部分は、COLORSの定義です。Tcl/Tkの本家のホームページにあった色定義 をコピペして作りました。ただ、実行時に2件、エラーが出ました。
TclError: unknown color name "agua"
TclError: unknown color name "crymson"
きっと単なるtypoですね。以下の通り修正しました。
"agua"
→ "aqua"
"crymson"
→ "crimson"
本家に修正依頼を出せればよいのでしょうけど、、、どこへ連絡すればよいのか分かりませんねぇ。と、いうことでこのtypoは放置するしかなさそうですね。
プログラムの方は、ラベルをつくって、マウスポインタがラベルに入ったら(<Enter>
イベントで)、ラベルに指定された色名と、RGB形式に変更した値をタイトルとして出力するように作りました。
いつも気になるのが、mainloop()
を書く位置なんだけど、スクリプトとして実行された後に書くか、__init__の最後で書くか、どっちがいいのかなぁ。たぶんどっちでもいいんだろうけど、メインアプリケーションとして実行されるなら、__init__の最後に書いておくのが正解なんじゃないかなぁ、と、思う今日この頃です。
