+\subsection{Dynamic sample}\label{sampledynamic}
+
+This sample is a very small sample that demonstrates the use of the
+\helpref{wxEvtHandler::Connect}{wxevthandlerconnect} method. This method
+should be used whenever it is not known at compile time, which control
+will receive which event or which controls are actually going to be in
+a dialog or frame. This is most typically the case for any scripting
+language that would work as a wrapper for wxWindows or programs where
+forms or similar datagrams can be created by the uses.
+
+See also the \helpref{event sample}{sampleevent}
+
+\subsection{Event sample}\label{sampleevent}
+
+The event sample demonstrates various features of the wxWindows events. It
+shows using dynamic events and connecting/disconnecting the event handlers
+during the run time and also using
+\helpref{PushEventHandler()}{wxwindowpusheventhandler} and
+\helpref{PopEventHandler()}{wxwindowpopeventhandler}.
+
+It replaces the old dynamic sample.
+
+\subsection{Exec sample}\label{sampleexec}
+
+The exec sample demonstrates the \helpref{wxExecute}{wxexecute} and
+\helpref{wxShell}{wxshell} functions. Both of them are used to execute the
+external programs and the sample shows how to do this synchronously (waiting
+until the program terminates) or asynchronously (notification will come later).
+
+It also shows how to capture the output of the child process in both
+synchronous and asynchronous cases and how to kill the processes with
+\helpref{wxProcess::Kill}{wxprocesskill} and test for their existence with
+\helpref{wxProcess::Exists}{wxprocessexists}.
+
+\subsection{Font sample}\label{samplefont}
+
+The font sample demonstrates \helpref{wxFont}{wxfont},
+\helpref{wxFontEnumerator}{wxfontenumerator} and
+\helpref{wxFontMapper}{wxfontmapper} classes. It allows you to see the fonts
+available (to wxWindows) on the computer and shows all characters of the
+chosen font as well.
+
+\subsection{Grid sample}\label{samplegrid}
+
+TODO.
+
+\subsection{HTML samples}\label{samplehtml}
+
+Eight HTML samples (you can find them in directory {\tt samples/html})
+cover all features of HTML sub-library.
+
+{\bf Test} demonstrates how to create \helpref{wxHtmlWindow}{wxhtmlwindow}
+and also shows most of supported HTML tags.
+
+{\bf Widget} shows how you can embed ordinary controls or windows within
+HTML page. It also nicely explains how to write new tag handlers and extend
+the library to work with unsupported tags.
+
+{\bf About} may give you an idea how to write good-looking about boxes.
+
+{\bf Zip} demonstrates use of virtual file systems in wxHTML. The zip archives
+handler (ships with wxWindows) allows you to access HTML pages stored
+in compressed archive as if they were ordinary files.
+
+{\bf Virtual} is yet another virtual file systems demo. This one generates pages at run-time.
+You may find it useful if you need to display some reports in your application.
+
+{\bf Printing} explains use of \helpref{wxHtmlEasyPrinting}{wxhtmleasyprinting}
+class which serves as as-simple-as-possible interface for printing HTML
+documents without much work. In fact, only few function calls are sufficient.
+
+{\bf Help} and {\bf Helpview} are variations on displaying HTML help
+(compatible with MS HTML Help Workshop). {\it Help} shows how to embed
+\helpref{wxHtmlHelpController}{wxhtmlhelpcontroller} in your application
+while {\it Helpview} is simple tool that only pops up help window and
+displays help books given at command line.
+
+\subsection{Image sample}\label{sampleimage}
+
+The image sample demonstrates the use of the \helpref{wxImage}{wximage} class
+and shows how to download images in a variety of formats, currently PNG, GIF,
+TIFF, JPEG, BMP, PNM and PCX. The top of the sample shows to rectangles, one
+of which is drawn directly in the window, the other one is drawn into a
+\helpref{wxBitmap}{wxbitmap}, converted to a wxImage, saved as a PNG image
+and then reloaded from the PNG file again so that conversions between wxImage
+and wxBitmap as well as loading and save PNG files are tested.
+
+At the bottom of the main frame is a test for using a monochrome bitmap by
+drawing into a \helpref{wxMemoryDC}{wxmemorydc}. The bitmap is then drawn
+specifying the foreground and background colours with
+\helpref{wxDC::SetTextForeground}{wxdcsettextforeground} and
+\helpref{wxDC::SetTextBackground}{wxdcsettextbackground} (on the left). The
+bitmap is then converted to a wxImage and the foreground colour (black) is
+replaced with red using \helpref{wxImage::Replace}{wximagereplace}.
+
+\subsection{Layout sample}\label{samplelayout}
+
+The layout sample demonstrates the two different layout systems offered
+by wxWindows. When starting the program, you will see a frame with some
+controls and some graphics. The controls will change their size whenever
+you resize the entire frame and the exact behaviour of the size changes
+is determined using the \helpref{wxLayoutConstraints}{wxlayoutconstraints}
+class. See also the \helpref{overview}{constraintsoverview} and the
+\helpref{wxIndividualLayoutConstraint}{wxindividuallayoutconstraint}
+class for further information.
+
+The menu in this sample offers two more tests, one showing how to use
+a \helpref{wxBoxSizer}{wxboxsizer} in a simple dialog and the other one
+showing how to use sizers in connection with a \helpref{wxNotebook}{wxnotebook}
+class. See also \helpref{wxNotebookSizer}{wxnotebooksizer} and
+\helpref{wxSizer}{wxsizer}.
+
+\subsection{Listctrl sample}\label{samplelistctrl}
+
+This sample shows \helpref{wxListCtrl}{wxlistctrl} control. Different modes
+supported by the control (list, icons, small icons, report) may be chosen from
+the menu.
+
+The sample also provides some timings for adding/deleting/sorting a lot of
+(several thousands) controls into the control.
+
+\subsection{Rotate sample}\label{samplerotate}
+
+This is a simple example which demonstrates how to rotate an image with
+the \helpref{wxImage::Rotate}{wximagerotate} method. The rotation can
+be done without interpolation (left mouse button) which will be faster,
+or with interpolation (right mouse button) which is slower but gives
+better results.
+
+\subsection{Scroll subwindow sample}\label{samplescrollsub}
+
+This sample demonstrates the use of the \helpref{wxScrolledWindow}{wxscrolledwindow}
+class including placing subwindows into it and drawing simple graphics. It uses the
+\helpref{SetTargetWindow}{wxscrolledwindowsettargetwindow} method and thus the effect
+of scrolling does not show in the scrolled window itself, but in one of its subwindows.
+
+Additionally, this samples demonstrates how to optimize drawing operations in wxWindows,
+in particular using the \helpref{wxWindow::IsExposed}{wxwindowisexposed} method with
+the aim to prevent unnecessary drawing in the window and thus reducing or removing
+flicker on screen.
+
+\subsection{Sockets sample}\label{samplesockets}
+
+The sockets sample demonstrates how to use the communication facilities
+provided by \helpref{wxSocket}{wxsocketbase}. There are two different
+applications in this sample: a server, which is implemented using a
+\helpref{wxSocketServer}{wxsocketserver} object, and a client, which
+is implemented as a \helpref{wxSocketClient}{wxsocketclient}.
+
+The server binds to the local address, using TCP port number 3000,
+sets up an event handler to be notified of incoming connection requests
+({\bf wxSOCKET\_CONNECTION} events), and stands there, waiting for clients
+({\it listening} in the socket parlance). For each accepted connection,
+a new \helpref{wxSocketBase}{wxsocketbase} object is created. These
+socket objects are independent from the server that created them, so
+they set up their own event handler, and then request to be notified
+of {\bf wxSOCKET\_INPUT} (incoming data) or {\bf wxSOCKET\_LOST}
+(connection closed at the remote end) events. In the sample, the event
+handler is the same for all connections; to find out which socket the
+event is addressed to, the \helpref{GetSocket}{wxsocketeventgetsocket} function
+is used.
+
+Although it might take some time to get used to the event-oriented
+system upon which wxSocket is built, the benefits are many. See, for
+example, that the server application, while being single-threaded
+(and of course without using fork() or ugly select() loops) can handle
+an arbitrary number of connections.
+
+The client starts up unconnected, so you can use the Connect... option
+to specify the address of the server you are going to connect to (the
+TCP port number is hard-coded as 3000). Once connected, a number of
+tests are possible. Currently, three tests are implemented. They show
+how to use the basic IO calls in \helpref{wxSocketBase}{wxsocketbase},
+such as \helpref{Read}{wxsocketbaseread}, \helpref{Write}{wxsocketbasewrite},
+\helpref{ReadMsg}{wxsocketbasereadmsg} and \helpref{WriteMsg}{wxsocketbasewritemsg},
+and how to set up the correct IO flags depending on what you are going to
+do. See the comments in the code for more information. Note that because
+both clients and connection objects in the server set up an event handler
+to catch {\bf wxSOCKET\_LOST} events, each one is immediately notified
+if the other end closes the connection.
+
+There is also an URL test which shows how to use
+the \helpref{wxURL}{wxurl} class to fetch data from a given URL.
+
+The sockets sample is work in progress. Some things to do:
+
+\begin{itemize}\itemsep=0pt
+\item More tests for basic socket functionality.
+\item More tests for protocol classes (wxProtocol and its descendants).
+\item Tests for the recently added (and still in alpha stage) datagram sockets.
+\item New samples which actually do something useful (suggestions accepted).
+\end{itemize}
+
+\subsection{Statbar sample}\label{samplestatbar}
+
+This sample shows how to create and use wxStatusBar. Although most of the
+samples have a statusbar, they usually only create a default one and only
+do it once.
+
+Here you can see how to recreate the statusbar (with possibly different number
+of fields) and how to use it to show icons/bitmaps and/or put arbitrary
+controls into it.
+
+\subsection{Text sample}\label{sampletext}
+
+This sample demonstrates four features: firstly the use and many variants of
+the \helpref{wxTextCtrl}{wxtextctrl} class (single line, multi line, read only,
+password, ignoring TAB, ignoring ENTER).
+
+Secondly it shows how to intercept a \helpref{wxKeyEvent}{wxkeyevent} in both
+the raw form using the {\tt EVT\_KEY\_UP} and {\tt EVT\_KEY\_DOWN} macros and the
+higher level from using the {\tt EVT\_CHAR} macro. All characters will be logged
+in a log window at the bottom of the main window. By pressing some of the function
+keys, you can test some actions in the text ctrl as well as get statistics on the
+text ctrls, which is useful for testing if these statistics actually are correct.
+
+Thirdly, on platforms which support it, the sample will offer to copy text to the
+\helpref{wxClipboard}{wxclipboard} and to paste text from it. The GTK version will
+use the so called PRIMARY SELECTION, which is the pseudo clipboard under X and
+best known from pasting text to the XTerm program.
+
+Last not least: some of the text controls have tooltips and the sample also shows
+how tooltips can be centrally disabled and their latency controlled.
+
+\subsection{Thread sample}\label{samplethread}
+
+This sample demonstrates the use of threads in connection with GUI programs.
+There are two fundamentally different ways to use threads in GUI programs and
+either way has to take care of the fact that the GUI library itself usually
+is not multi-threading safe, i.e. that it might crash if two threads try to
+access the GUI class simultaneously. One way to prevent that is have a normal
+GUI program in the main thread and some worker threads which work in the
+background. In order to make communication between the main thread and the
+worker threads possible, wxWindows offers the \helpref{wxPostEvent}{wxpostevent}
+function and this sample makes use of this function.
+
+The other way to use a so called Mutex (such as those offered in the \helpref{wxMutex}{wxmutex}
+class) that prevent threads from accessing the GUI classes as long as any other
+thread accesses them. For this, wxWindows has the \helpref{wxMutexGuiEnter}{wxmutexguienter}
+and \helpref{wxMutexGuiLeave}{wxmutexguileave} functions, both of which are
+used and tested in the sample as well.
+
+See also \helpref{Multithreading overview}{wxthreadoverview} and \helpref{wxThread}{wxthread}.
+
+\subsection{Toolbar sample}\label{sampletoolbar}
+
+The toolbar sample shows the \helpref{wxToolBar}{wxtoolbar} class in action.
+
+The following things are demonstrated:
+
+\begin{itemize}\itemsep=0pt
+\item Creating the toolbar using \helpref{wxToolBar::AddTool}{wxtoolbaraddtool}
+and \helpref{wxToolBar::AddControl}{wxtoolbaraddcontrol}: see
+MyApp::InitToolbar in the sample.
+\item Using {\tt EVT\_UPDATE\_UI} handler for automatically enabling/disabling
+toolbar buttons without having to explicitly call EnableTool. This is done
+in MyFrame::OnUpdateCopyAndCut.
+\item Using \helpref{wxToolBar::DeleteTool}{wxtoolbardeletetool} and
+\helpref{wxToolBar::InsertTool}{wxtoolbarinserttool} to dynamically update the
+toolbar.
+\end{itemize}
+
+Some buttons in the main toolbar are check buttons, i.e. they stay checked when
+pressed. On the platforms which support it, the sample also add a combobox
+to the toolbar showing how you can use arbitrary controls and not only buttons
+in it.
+
+If you toggle another toolbar in the sample (using {\tt Ctrl-A}) you will also
+see the radio toolbar buttons in action: the first three buttons form a radio
+group, that is checking any of them automatically unchecks the previously
+checked one.
+
+\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})
+\end{itemize}
+
