* Tkinter functions and constructors which need a default root window
raise now RuntimeError with descriptive message instead of obscure
AttributeError or NameError if it is not created yet or cannot
be created automatically.
* Add tests for all functions which use default root window.
* Fix import in the pynche script.

# base class for tk common dialogues

# this module provides a base class for accessing the common
|
|
# dialogues available in Tk 4.2 and newer. use filedialog,
|
|
# colorchooser, and messagebox to access the individual
|
|
# dialogs.
