+Probably the best way to learn wxWidgets is by reading the source of some 50+
+samples provided with it. Many aspects of wxWidgets programming can be learnt
from them, but sometimes it is not simple to just choose the right sample to
look at. This overview aims at describing what each sample does/demonstrates to
make it easier to find the relevant one if a simple grep through all sources
didn't help. They also provide some notes about using the samples and what
-features of wxWindows are they supposed to test.

+\helpref{minimal sample}{sampleminimal} which is the wxWidgets version of
+"Hello, world!". It shows the basic structure of wxWidgets program and is the
most commented sample of all - looking at its source code is recommended.
-The next most useful sample is probably the \helpref{controls}{samplecontrols}
-one which shows many of wxWindows standard controls, such as buttons,
-listboxes, checkboxes, comboboxes etc.
+The next most useful samples are probably \helpref{widgets}{samplewidgets}
+and \helpref{controls}{samplecontrols} which show many of wxWidgets native and
+generic controls, such as buttons, listboxes, checkboxes, comboboxes etc.
Other, more complicated controls, have their own samples. In this category you
may find the following samples showing the corresponding controls:

\subsection{Minimal sample}\label{sampleminimal}
The minimal sample is what most people will know under the term Hello World,
i.e. a minimal program that doesn't demonstrate anything apart from what is
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
+wxWidgets 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.
+
\subsection{Calendar sample}\label{samplecalendar}
shows how to configure the control (see the different options in the calendar
menu) and also how to process the notifications from it.
+
\subsection{Checklist sample}\label{samplechecklist}
-This sample demonstrates the use of the \helpref{wxCheckListBox}{wxchecklistbox}
-class intercepting check, select and double click events. It also tests the
-use of various methods modifiying the control, such as by deleting items

+from it or inserting new ones (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
+independent 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
features of this class.

\subsection{Controls sample}\label{samplecontrols}
The controls sample is the main test program for most simple controls used in
-wxWindows. The sample tests their basic functionality, events, placement,
+wxWidgets. The sample tests their basic functionality, events, placement,
modification in terms of colour and font as well as the possibility to change

\subsection{Database sample}\label{sampledb}
The database sample is a small test program showing how to use the ODBC
-classes written by Remstar Intl. These classes are documented in a separate
-manual available from the wxWindows homepage. Obviously, this sample

+database with ODBC support to be correctly installed on your system.
-\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{DebugRpt sample}\label{sampledebugrpt}
-\subsection{Dynamic sample}\label{sampledynamic}
+This sample shows how to use \helpref{wxDebugReport}{wxdebugreport} class to
+generate a debug report in case of a program crash or otherwise. On start up,
+it proposes to either crash itself (by dereferencing a NULL pointer) or
+generate debug report without doing it. Next it initializes the debug report
+with standard information adding a custom file to it (just a timestamp) and
+allows to view the information gathered using
+\helpref{wxDebugReportPreview}{wxdebugreportpreview}.
-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.
+For the report processing part of the sample to work you should make available
+a Web server accepting form uploads, otherwise
+\helpref{wxDebugReportUpload}{wxdebugreportupload} will report an error.
-\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).
+\subsection{Dialogs sample}\label{sampledialogs}
-\subsection{Scroll subwindow sample}\label{samplescrollsub}
+This sample shows how to use the common dialogs available from wxWidgets. These
+dialogs are described in detail in the \helpref{Common dialogs overview}{commondialogsoverview}.
-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{Dialup sample}\label{sampledialup}
-\subsection{Font sample}\label{samplefont}
+This sample shows the \helpref{wxDialUpManager}{wxdialupmanager}
+class. In the status bar, it displays 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 be on a LAN not
+connected to the Internet, in which case you will not see this) or not.
+
+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.
-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{DnD sample}\label{samplednd}

+
+This sample is a very small sample that demonstrates use of the
+\helpref{wxEvtHandler::Connect}{wxevthandlerconnect} method. This method
+should be used whenever it is not known at compile time which control

+
+See also the \helpref{event sample}{sampleevent}
+
+
+\subsection{Event sample}\label{sampleevent}
+
+The event sample demonstrates various features of the wxWidgets events. It
+shows using dynamic events and connecting/disconnecting the event handlers
+during run time and also using
+\helpref{PushEventHandler()}{wxwindowpusheventhandler} and
+\helpref{PopEventHandler()}{wxwindowpopeventhandler}.
+
+It replaces the old dynamic sample.
+
+
+\subsection{Except(ions) sample}\label{sampleexcept}
+
+This very simple sample shows how to use C++ exceptions in wxWidgets programs,
+i.e. where to catch the exception which may be thrown by the program code. It
+doesn't do anything very exciting by itself, you need to study its code to
+understand what goes on.
+
+You need to build the library with \texttt{wxUSE\_EXCEPTIONS} being set to $1$
+and compile your code with C++ exceptions support to be able to build this
+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 not very clearly named internat sample demonstrates the wxWidgets
+internationalization (i18n for short from now on) features. To be more
+precise, it only shows localization support, i.e. support for translating the

+This sample demonstrates 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

\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 sits there, waiting for clients
+({\it listening}, in 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
such as \helpref{Read}{wxsocketbaseread}, \helpref{Write}{wxsocketbasewrite},
\helpref{ReadMsg}{wxsocketbasereadmsg} and \helpref{WriteMsg}{wxsocketbasewritemsg},

+This sample demonstrates 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

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}
+thread accesses them. For this, wxWidgets has the \helpref{wxMutexGuiEnter}{wxmutexguienter}
and \helpref{wxMutexGuiLeave}{wxmutexguileave} functions, both of which are
used and tested in the sample as well.

+see the radio toolbar buttons in action: the first three buttons form a radio
+group, i.e. checking any of them automatically unchecks the previously
+checked one.

+This sample demonstrates using the \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).
sorting (in default alphabetical order as well as in custom one) is
demonstrated here as well - try the corresponding menu entries.

+\subsection{Widgets sample}\label{samplewidgets}
+
+The widgets sample is the main presentation program for most simple and advanced
+native controls and complex generic widgets provided by wxWidgets.
+The sample tests their basic functionality, events, placement, modification
+in terms of colour and font as well as the possibility to change
+the controls programmatically, such as adding an item to a list box etc.
+All widgets are categorized for easy browsing.
+
+\subsection{Wizard sample}\label{samplewizard}
+
+This sample shows the 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 the {\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}
