needed to write a program that will display a "hello" dialog. This is usually
a good starting point for learning how to use wxWindows.
+\subsection{Art provider sample}\label{sampleartprovider}
+
+The {\tt artprov} sample shows how you can customize the look of standard
+wxWindows dialogs by replacing default bitmaps/icons with your own versions.
+It also shows how you can use wxArtProvider to
+get stock bitmaps for use in your application.

+from it or inserting new once (these functions are actually implemented in
the parent class \helpref{wxListBox}{wxlistbox} so the sample tests that class
as well). The layout of the dialog is created using a \helpref{wxBoxSizer}{wxboxsizer}
demonstrating a simple dynamic layout.
\subsection{Config sample}\label{sampleconfig}
This sample demonstrates the \helpref{wxConfig}{wxconfigbase} classes in a platform
-indepedent way, i.e. it uses text based files to store a given configuration under

Unix and uses the Registry under Windows.
See \helpref{wxConfig overview}{wxconfigoverview} for the descriptions of all
modification in terms of colour and font as well as the possibility to change
the controls programmatically, such as adding item to a list box etc. Apart
from that, the sample uses a \helpref{wxNotebook}{wxnotebook} and tests most

\subsection{Dialogs sample}\label{sampledialogs}
This sample shows how to use the common dialogs available from wxWindows. These
-dialogs are desrcibed in details in the \helpref{Common dialogs overview}{commondialogsoverview}.
-
-\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
-languge that would work as a wrapper for wxWindows or programs where
-forms or similar datagrams can be created by the uses.
+dialogs are described in details in the \helpref{Common dialogs overview}{commondialogsoverview}.
-\subsection{Exec sample}\label{sampleexec}
+\subsection{Dialup sample}\label{sampledialup}
-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).
+This sample shows \helpref{wxDialUpManager}{wxdialupmanager}
+class. It displays in the status bar the information gathered through its
+interface: in particular, the current connection status (online or offline) and
+whether the connection is permanent (in which case a string `LAN' appears in
+the third status bar field - but note that you may have be on a LAN not
+connected to the Internet, in which case you will not see this) or not.
-\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{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.
+Using the menu entries, you may also dial or hang up the line if you have a
+modem attached and (this only makes sense for Windows) list the available
+connections.
\subsection{DnD sample}\label{samplednd}
Take a look at DnDShapeDataObject class to see how you may use
\helpref{wxDataObject}{wxdataobject} to achieve this.
+\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.

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

and wxBitmap as well as loading and save PNG files are tested.
bitmap is then converted to a wxImage and the foreground colour (black) is
replaced with red using \helpref{wxImage::Replace}{wximagereplace}.
+\subsection{Internat(ionalization) sample}\label{sampleinternat}
+
+The not very clearly named internat sample demonstrates the wxWindows
+internatationalization (i18n for short from now on) features. To be more
+precise, it only shows localization support, i.e. support for translating the
+program messages in another language while true i18n would also involve
+changing the other aspects of the programs behaviour.
+
+More information about this sample can be found in the {\tt readme.txt} file in
+its directory. Please see also \helpref{i18n overview}{internationalization}.

\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

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{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 as a
-\helpref{wxSocketServer}{wxsocketserver} object, and a client, which is
-implemented with \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} event), and stands there, waiting (listening
-in the socket parlance) for clients. For each incoming client, a new
-\helpref{wxSocketBase}{wxsocketbase} object is created, which represents
-the connection. Connections are independent from the server that created
-them, so they set up their own event handler, and stay awaiting for
-{\bf wxSOCKET\_INPUT} (incoming data) or {\bf wxSOCKET\_LOST} (connection
-closed at the remote end) events. This event handler is the same for all
-connections, and demonstrates how to determine which socket the event
-is addressed to by using the \helpref{Socket}{wxsocketeventsocket} function
-in the \helpref{wxSocketEvent}{wxsocketevent} class.

+
+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
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},

+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
