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,
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.
Checkbutton, Scale, Listbox, Scrollbar, OptionMenu, Spinbox
LabelFrame and PanedWindow.
Properties of the widgets are specified with keyword arguments.
Keyword arguments have the same name as the corresponding resource
under Tk.
Widgets are positioned with one of the geometry managers Place, Pack
or Grid. These managers can be called with methods place, pack, grid

after window
Insert the window after the window specified. window
should be the name of a window already managed by pathName.
before window
Insert the window before the window specified. window
should be the name of a window already managed by pathName.
height size
Specify a height for the window. The height will be the
outer dimension of the window including its border, if
any. If size is an empty string, or if -height is not
specified, then the height requested internally by the
window will be used initially; the height may later be
adjusted by the movement of sashes in the panedwindow.
Size may be any value accepted by Tk_GetPixels.

Specifies that the size of the window cannot be made
less than n. This constraint only affects the size of
the widget in the paned dimension -- the x dimension
for horizontal panedwindows, the y dimension for
vertical panedwindows. May be any value accepted by
Tk_GetPixels.
padx n
Specifies a non-negative value indicating how much
extra space to leave on each side of the window in
the X-direction. The value may have any of the forms
accepted by Tk_GetPixels.
pady n
Specifies a non-negative value indicating how much
extra space to leave on each side of the window in
the Y-direction. The value may have any of the forms
accepted by Tk_GetPixels.
sticky style
If a window's pane is larger than the requested
dimensions of the window, this option may be used
to position (or stretch) the window within its pane.
Style is a string that contains zero or more of the
characters n, s, e or w. The string can optionally
contains spaces or commas, but they are ignored. Each
letter refers to a side (north, south, east, or west)
that the window will "stick" to. If both n and s
(or e and w) are specified, the window will be
stretched to fill the entire height (or width) of
its cavity.
width size

the outer dimension of the window including its
border, if any. If size is an empty string, or
if -width is not specified, then the width requested
internally by the window will be used initially; the
width may later be adjusted by the movement of sashes
