An Overview of The Tkinter Classes

The class hierarchy looks complicated, but in actual practice, application programmers almost always refer to the classes at the very bottom of the hierarchy.

Here are links [which ought to be embedded in the graphic; eventually] to the interfaces for each of the concrete widgets:

Button Canvas Checkbutton Entry Frame Label Listbox Menu Menubutton Message *Misc *Pack *Place Radiobutton Scale Scrollbar Text **Tk Toplevel ***Widget *Wm

Notes:

* These classes are provided for the purposes of organizing certain functions under one namespace. They aren't meant to be instantiated independently.
** The Tk class is meant to be instantiated only once in an application. Application programmers need not instantiate one explicitly, the system creates one whenever any of the other classes are instantiated.
*** The Widget class is not meant to be instantiated, it is meant only for subclassing to make ``real'' widgets. (in C++, this is called an `abstract class')
