"wx.Sizer is the abstract base class used for laying out subwindows in
a window. You cannot use wx.Sizer directly; instead, you will have to
use one of the sizer classes derived from it such as `wx.BoxSizer`,
-`wx.StaticBoxSizer`, `wx.NotebookSizer`, `wx.GridSizer`, `wx.FlexGridSizer`
-and `wx.GridBagSizer`.
+`wx.StaticBoxSizer`, `wx.GridSizer`, `wx.FlexGridSizer` and
+`wx.GridBagSizer`.
The concept implemented by sizers in wxWidgets is closely related to
layout tools in other GUI toolkits, such as Java's AWT, the GTK
more space than on Windows, then the initial size of a dialog using a
sizer will automatically be bigger on Mac than on Windows.", "
+Sizers may also be used to control the layout of custom drawn items on
+the window. The `Add`, `Insert`, and `Prepend` functions return a
+pointer to the newly added `wx.SizerItem`. Just add empty space of the
+desired size and attributes, and then use the `wx.SizerItem.GetRect`
+method to determine where the drawing operations should take place.
+
:note: If you wish to create a custom sizer class in wxPython you
should derive the class from `wx.PySizer` in order to get
Python-aware capabilities for the various virtual methods.
