Tkinterでツールチップを表示するにはどうすればよいですか？
ツールチップとは、一定期間マウスをウィジェットの上に置いたときにポップアップ表示されるテキストです。
tkinter Pythonアプリケーションにツールチップメッセージを追加するにはどうすればよいですか？
Tkinterの Pmw.BalloonPmw toolkit のクラスは、ツールヒントを描画します。
Tkinterでツールヒントを表示するために使用されるIDLEのコードを適応させる ブログ投稿 もご覧ください。
ars で言及された ブログ投稿 のコードを試しました IDLE lib のコードも試しました。
どちらも機能していましたが、IDLEのツールチップのサイズが制限されていて（手動で新しい行を個別のリストとして入力しなければなりませんでした）、ヒントがブログの投稿のコードにすぐに表示されていました。
だから私は両者のハイブリッドを作りました。ラップの長さとホバー時間を指定できます。それぞれに制限はありません。

スクリーンショット：
まず、私は本当に気に入っています Alberto Vassenaのツールチップ と彼の投稿にこのバグ修正を加えてコメントしようとしましたが、新しいユーザーとして、コメントするのに十分なポイントがないので、答えを出す。これが許容できることを願っています。
Alberto Vassenaの優れた答え に非常に小さなバグがあり、ツールヒントが改善されました。
バグ：実際のラベルについて、彼のコードはtk.Labelではなくttk.Labelを呼び出します。これにより、ツールチップボックスがレンダリングされますが、別のマウスの移動やキーボードイベントなどのUIイベントが発生するまで、実際のテキストはレンダリングされません。

モジュールを直接インポートして使用することもできます：
from idlelib.ToolTip import *
def main():
root = Tk()
b = Button(root, text="Hello", command=root.destroy)
b.pack()
root.update()
tip = ListboxToolTip(b, ["Hello", "world"])
root.mainloop()
if __name__ == '__main__':
main()
Python 3.4を使用しています。他のPythonのディストリビューションにこのToolTipモジュールが含まれていない可能性があります。
Tooltipクラスを変更しましたcrxguy52が提案しました。次のクラスは、インスタンス化する必要があるほとんどすべての場合に機能するはずです：[〜＃〜] nw [〜＃〜]、 [〜＃〜] n [〜＃〜]、[〜＃〜] ne [〜＃〜]、[〜 ＃〜] e [〜＃〜]、[〜＃〜] se [〜＃〜]、[〜＃〜 ] s [〜＃〜]、[〜＃〜] sw [〜＃〜]、[〜＃〜] w [〜＃〜]。
私のクラスが現在管理していない唯一のケースは、ツールチップが画面全体よりも単に高い場合です（おそらく非常にまれですが、手動でより大きいwraplengthもそのケースをすぐに解決できます）。
