+\subsection{Treectrl sample}\label{sampletreectrl}
+
+This sample demonstrates using \helpref{wxTreeCtrl}{wxtreectrl} class. Here
+you may see how to process various notification messages sent by this control
+and also when they occur (by looking at the messages in the text control in
+the bottom part of the frame).
+
+Adding, inserting and deleting items and branches from the tree as well as
+sorting (in default alphabetical order as well as in custom one) is
+demonstrated here as well - try the corresponding menu entries.
+
+\subsection{Wizard sample}\label{samplewizard}
+
+This sample shows so-called wizard dialog (implemented using
+\helpref{wxWizard}{wxwizard} and related classes). It shows almost all
+features supported:
+
+\begin{itemize}\itemsep=0pt
+\item Using bitmaps with the wizard and changing them depending on the page
+shown (notice that wxValidationPage in the sample has a different image from
+the other ones)
+\item Using \helpref{TransferDataFromWindow}{wxwindowtransferdatafromwindow}
+to verify that the data entered is correct before passing to the next page
+(done in wxValidationPage which forces the user to check a checkbox before
+continuing).
+\item Using more elaborated techniques to allow returning to the previous
+page, but not continuing to the next one or vice versa (in wxRadioboxPage)
+\item This (wxRadioboxPage) page also shows how the page may process {\tt
+Cancel} button itself instead of relying on the wizard parent to do it.
+\item Normally, the order of the pages in the wizard is known at compile-time,
+but sometimes it depends on the user choices: wxCheckboxPage shows how to
+dynamically decide which page to display next (see also
+\helpref{wxWizardPage}{wxwizardpage})
