TkTreectrl 介绍
TkTreectrl (TkinterTreectrl) 模块封装了 treectrl Tk 扩展以便在
Python/Tkinter 中使用。
The treectrl widget allows you to create fancy things like sortable multi-
column list boxes and hierarchical tree views in Tkinter. The package also
includes a ready to use multi-column listbox widget, scrolled Treectrl, and
multi-column list box widgets plus a generic ScrolledWidget class that makes
it quite easy to add one or two static or automatic scroll bars to any
listbox-alike Tkinter widget.
