\section{\class{wxSizer}}\label{wxsizer}
wxSizer is the abstract base class used for laying out subwindows in a window. You
-cannot use wxSizer directly; instead, you'll have to use \helpref{wxBoxSizer}{wxboxsizer}
-or \helpref{wxStaticBoxSizer}{wxstaticboxsizer}.

The layout algorithm used by sizers in wxWindows is closely related to layout
in other GUI toolkits, such as Java's AWT, the GTK toolkit or the Qt toolkit. It is
on Windows, the intial dialog size will automatically be bigger on Motif than on Windows.
\pythonnote{If you wish to create a sizer class in wxPython you should
-derive the class from \tt{wxPySizer} in order to get Python-aware
+derive the class from {\tt wxPySizer} in order to get Python-aware
capabilities for the various virtual methods.}
