# Pmw megawidget base classes.

|
|
# This module provides a foundation for building megawidgets. It
|
||
|
|
# contains the MegaArchetype class which manages component widgets and
|
||
|
|
# configuration options. Also provided are the MegaToplevel and
|
||
|
|
# MegaWidget classes, derived from the MegaArchetype class. The
|
||
|
|
# MegaToplevel class contains a Tkinter Toplevel widget to act as the
|
||
|
|
# container of the megawidget. This is used as the base class of all
|
||
|
|
# megawidgets that are contained in their own top level window, such
|
||
|
|
# as a Dialog window. The MegaWidget class contains a Tkinter Frame
|
||
|
|
# to act as the container of the megawidget. This is used as the base
|
||
|
|
# class of all other megawidgets, such as a ComboBox or ButtonBox.
|
||
|
|
#
|
||
|
|
# Megawidgets are built by creating a class that inherits from either
|
||
|
|
# the MegaToplevel or MegaWidget class.

# does not have the grab or focus). For example, if a modal

|
|
# dialog is deleted by the window manager or deactivated by

|
|
# a timer. In this case, all dialogs above and including

# stack.
