  18 # LearnSizer*.py is a small application aimed to learn the sizers and
  19 # their usage.
  20 # This application is a collection of panels. Each panel contains
  21 # a few widgets laid out with sizers. The panels are numbered
  22 # MyPanel_0 to MyPanel_n. The panel 0 is the simpliest case. The
  23 # order of the panels follows an increasing complexity in the
  24 # layout. It is warmly recommended to start with MyPanel_0.
  25 #
  26 # Do not forget :
  27 # - the wxPython doc
  28 # - the wiki page http://wiki.wxpython.org/index.cgi/UsingSizers
  29 # - dir(<instance of a sizer>) for a list of methods
  30 # - print sizer.method.__doc__
