+#	From http://docs.wxwidgets.org/trunk/overview_windowsizing.html, wxWidgets provides two main methods for sizing:
+#
+#   Fit() sets the size of a window to fit around its children. 
+#	The size of each children is added and then this parent window changes its size to fit them all.
+#   Layout() the opposite. The children will change their size, according to sizer rules, so they can fit into available space of their parent. 
+#	[...] is what is called by the default EVT_SIZE handler for container windows
+
+#	Because a grid can have thousands of rows/cols its size can be huge. 
+#	Don't try to tell the parent to fit around it. 
+#	You better set max and min sizes for the grid (or its sizer) and then use Fit() or Layout() each time you change number of rows/cols or their sizes.
