# LearnSizer*.py is a small application aimed to learn the sizers and
# their usage.
# This application is a collection of panels. Each panel contains
# a few widgets laid out with sizers. The panels are numbered
# MyPanel_0 to MyPanel_n. The panel 0 is the simplest case. The
# order of the panels follows an increasing complexity in the
# layout. It is warmly recommended to start with MyPanel_0.
#
# Do not forget:
# - the wxPython doc
# - the wiki page http://wiki.wxpython.org/index.cgi/UsingSizers
# - dir(<instance of a sizer>) for a list of methods
# - print sizer.method.__doc__
