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