# wx.BoxSizer: a row or a column. We can put another sizer into an existing sizer.
# wx.StaticBoxSizer: Identical to a wx.BoxSizer, with the one addition of a border (and optional
# caption) around the box.
# wx.GridSizer lays out widgets in two dimensional table.
# Each cell within the table has the same size.
# wx.FlexGridSizer: All cells in a row have the same height.
# All cells in a column have the same width.
# But all rows and columns are not necessarily the same height or width.
# box.Add(wx.Window window, integer proportion=0, integer flag = 0, integer border = 0)
# proportion: 0 - Do not change size
# it is relative, item with 2 changes twice the degree of item with 1

# wx.RIGHT
# wx.BOTTOM
# wx.TOP
# wx.ALL: all the above are border margin flags
