以 Tk 打造圖形使用者介面 (Graphical User Interfaces)
****************************************************

Tk/Tcl 長期以來一直是 Python 不可或缺的一部分。它提供了一個強大且獨立
於平台的視窗工具包，可供使用 "tkinter" 套件及其擴充套件 "tkinter.tix"
和 "tkinter.ttk" 模組的 Python 開發者使用。

"tkinter" 套件是 Tcl/Tk 之上的一個輕薄物件導向層。要使用 "tkinter"，你
不需要編寫 Tcl 程式，但會需要查閱 Tk 文件和部份 Tcl 文件。"tkinter" 是
一組將 Tk 小工具 (widget) 實作為 Python 類別的包裝器。

"tkinter" 的主要優點是速度快，而且通常與 Python 捆綁 (bundle) 在一起。
儘管其標準文件不是很完整，但還是有些不錯的材料，包括：參考資料、教學、
書籍等。"tkinter" 曾因其過時的外觀而眾所皆知，但這在 Tk 8.5 中得到了極
大的改進。此外，還有許多其他你可能會感興趣的 GUI 函式庫。Python wiki
列出了幾個替代的 GUI 框架和工具。
