"""Wrapper functions for Tcl/Tk.

|
|
|
|
|
Tkinter provides classes which allow the display, positioning and
|
|
|
|
control of widgets. Toplevel widgets are Tk and Toplevel. Other
|
|
|
|
widgets are Frame, Label, Entry, Text, Canvas, Button, Radiobutton,
|
2001-09-02 02:29:55 +08:00
|
|
|
Checkbutton, Scale, Listbox, Scrollbar, OptionMenu. Properties of the
|
|
|
|
widgets are specified with keyword arguments. Keyword arguments have
|
|
|
|
the same name as the corresponding resource under Tk.
|
2000-06-30 00:30:50 +08:00
|
|
|
|
|
|
|
Widgets are positioned with one of the geometry managers Place, Pack
|
|
|
|
or Grid. These managers can be called with methods place, pack, grid
|
|
|
|
available in every Widget.
|
|
|
|
|
2001-09-02 02:29:55 +08:00
|
|
|
Actions are bound to events by resources (e.g. keyword argument
|
|
|
|
command) or with the method bind.
