Overview of the examples provided with wxWidgets.
Probably the best way to learn wxWidgets is by reading the source of some 80+ 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 wxWidgets are they supposed to test.
There are currently more than 80 different samples as part of wxWidgets: the list in this page is not complete! You should start your tour of wxWidgets with the Minimal Sample 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 Widgets Sample which shows many of wxWidgets controls, such as buttons, text entry zones, list boxes, check boxes, combo boxes etc. It is organized in many different source files, one per each control, which makes it easier to study it, and also allows to change various control styles and call its methods interactively.
Other, more complicated controls, have their own samples. In this category you may find the following samples showing the corresponding controls:
Finally, here is the full list of samples:
Notice that all wxWidgets samples mentioned above can be found in samples subdirectory of the library distribution. When a foobar sample is mentioned below, its sources can be found in samples/foobar directory of your wxWidgets tree. If you installed wxWidgets from a binary package, you might not have this directory. In this case, you may view the samples online at http://svn.wxwidgets.org/viewvc/wx/wxWidgets/trunk/samples/ but you need to download the source distribution in order to be able to build them (highly recommended).
Final advice is to do a search in the entire samples directory if you can't find the sample showing the control you are interested in by name. Most classes contained in wxWidgets occur in at least one of the samples.
This sample shows how you can use the wxAccessible classes in a simple GUI program.
Build Note: You may need to build the wxWidgets library with wxUSE_ACCESSIBILITY being set to 1 to be able to make it work, please read comments in <wx/setup_inc.h> for more info.

This sample demonstrates AUI classes.
Location: samples/aui subdirectory of your wxWidgets installation or http://svn.wxwidgets.org/viewvc/wx/wxWidgets/trunk/samples/aui
This sample shows the calendar control in action. It shows how to configure the control (see the different options in the calendar menu) and also how to process the notifications from it.
Location: samples/calendar subdirectory of your wxWidgets installation or http://svn.wxwidgets.org/viewvc/wx/wxWidgets/trunk/samples/calendar
This sample demonstrates wxCaret.

This sample demonstrates wxComboBox, wxComboCtrl and wxOwnerDrawnComboBox etc.
Location: samples/combo subdirectory of your wxWidgets installation or http://svn.wxwidgets.org/viewvc/wx/wxWidgets/trunk/samples/combo
This sample demonstrates the wxConfig classes in a platform independent way, i.e. it uses text based files to store a given configuration under Unix and uses the Registry under Windows.
See wxConfig Overview for the descriptions of all features of this class.
Location: samples/config subdirectory of your wxWidgets installation or http://svn.wxwidgets.org/viewvc/wx/wxWidgets/trunk/samples/config
This sample demonstrates a console program.
Location: samples/console subdirectory of your wxWidgets installation or http://svn.wxwidgets.org/viewvc/wx/wxWidgets/trunk/samples/console
The controls sample is the main test program for most simple controls used in 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. Apart from that, the sample uses a wxNotebook and tests most features of this special control (using bitmap in the tabs, using wxSizer instances and wxLayoutConstraints within notebook pages, advancing pages programmatically and vetoing a page change by intercepting the wxNotebookEvent.
The various controls tested are listed here:
Location: samples/controls subdirectory of your wxWidgets installation or http://svn.wxwidgets.org/viewvc/wx/wxWidgets/trunk/samples/controls
This sample demonstrates wxDataViewCtrl.
Location: samples/dataview subdirectory of your wxWidgets installation or http://svn.wxwidgets.org/viewvc/wx/wxWidgets/trunk/samples/dataview
This sample demonstrates wxClipboard.
Location: samples/clipboard subdirectory of your wxWidgets installation or http://svn.wxwidgets.org/viewvc/wx/wxWidgets/trunk/samples/clipboard
This sample shows how to use 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 wxDebugReportPreview.
For the report processing part of the sample to work you should make available a Web server accepting form uploads, otherwise wxDebugReportUpload will report an error.
Build Note: You may need to build the wxWidgets library with wxUSE_DEBUGREPORT and wxUSE_ON_FATAL_EXCEPTION being set to 1 to be able to make it work, please read comments in <wx/setup_inc.h> for more info.
Location: samples/debugrpt subdirectory of your wxWidgets installation or http://svn.wxwidgets.org/viewvc/wx/wxWidgets/trunk/samples/debugrpt
This sample shows how to use the common dialogs available from wxWidgets. These dialogs are described in detail in the Common Dialogs.
In addition to the dialogs accessible from the sample menus, you can also run it with a --progress=style command line option to show a wxProgressDialog with the given style (try 0 for the default style) on program startup, before the main window is shown.
Location: samples/dialogs subdirectory of your wxWidgets installation or http://svn.wxwidgets.org/viewvc/wx/wxWidgets/trunk/samples/dialogs
This sample shows the 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.
Location: samples/dialup subdirectory of your wxWidgets installation or http://svn.wxwidgets.org/viewvc/wx/wxWidgets/trunk/samples/dialup
This sample demonstrates wxDisplay.
Location: samples/display subdirectory of your wxWidgets installation or http://svn.wxwidgets.org/viewvc/wx/wxWidgets/trunk/samples/display
This sample shows both clipboard and drag and drop in action. It is quite non trivial and may be safely used as a basis for implementing the clipboard and drag and drop operations in a real-life program.
When you run the sample, its screen is split in several parts. On the top, there are two listboxes which show the standard derivations of wxDropTarget: wxTextDropTarget and wxFileDropTarget.
The middle of the sample window is taken by the log window which shows what is going on (of course, this only works in debug builds) and may be helpful to see the sequence of steps of data transfer.
Finally, the last part is used for dragging text from it to either one of the listboxes (only one will accept it) or another application. The last functionality available from the main frame is to paste a bitmap from the clipboard (or, in the case of the Windows version, also a metafile) - it will be shown in a new frame.
So far, everything we mentioned was implemented with minimal amount of code using standard wxWidgets classes. The more advanced features are demonstrated if you create a shape frame from the main frame menu. A shape is a geometric object which has a position, size and color. It models some application-specific data in this sample. A shape object supports its own private wxDataFormat which means that you may cut and paste it or drag and drop (between one and the same or different shapes) from one sample instance to another (or the same). However, chances are that no other program supports this format and so shapes can also be rendered as bitmaps which allows them to be pasted/dropped in many other applications (and, under Windows, also as metafiles which are supported by most of Windows programs as well - try Write/Wordpad, for example).
Take a look at DnDShapeDataObject class to see how you may use wxDataObject to achieve this.

This sample demonstrates wxEraseEvent.
Location: samples/erase subdirectory of your wxWidgets installation or http://svn.wxwidgets.org/viewvc/wx/wxWidgets/trunk/samples/erase
This sample demonstrates various features of the wxWidgets events. It shows how to dynamic events and connecting/disconnecting the event handlers during run time by using wxEvtHandler::Connect() and wxEvtHandler::Disconnect(), and also how to use wxWindow::PushEventHandler() and wxWindow::PopEventHandler().
Location: samples/event subdirectory of your wxWidgets installation or http://svn.wxwidgets.org/viewvc/wx/wxWidgets/trunk/samples/event
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.
Build Note: You need to build the library with wxUSE_EXCEPTIONS being set to 1 and compile your code with C++ exceptions support to be able to build this sample.
Location: samples/except subdirectory of your wxWidgets installation or http://svn.wxwidgets.org/viewvc/wx/wxWidgets/trunk/samples/except
The exec sample demonstrates the wxExecute and 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 wxProcess::Kill() and test for their existence with wxProcess::Exists().
Location: samples/exec subdirectory of your wxWidgets installation or http://svn.wxwidgets.org/viewvc/wx/wxWidgets/trunk/samples/exec
The flash sample demonstrates embedding of Adobe Flash into a wxWidgets program. Currently it only works under Windows as it uses the Flash ActiveX control to achieve this but we hope to be able to extend it to also work under other platforms in the future. The sample also currently requires Microsoft Visual C++ compiler as it uses COM support extensions specific to this compiler.
The sample comes with 2 Flash files (SWF), showing a simple Flash animation which can be controlled using the "Play", "Stop" and "Back"/"Forward" buttons in the sample as well as a Flash form which shows how Flash and wxWidgets program can exchange data: calling "GetText" function without arguments returns the text of the text control defined inside Flash and calling "SetText" with an argument sets the control contents to the given string. Finally clicking on the button generates an event which is caught by the C++ program.
The font sample demonstrates wxFont, wxFontEnumerator and wxFontMapper classes. It allows you to see the fonts available (to wxWidgets) on the computer and shows all characters of the chosen font as well.
Location: samples/font subdirectory of your wxWidgets installation or http://svn.wxwidgets.org/viewvc/wx/wxWidgets/trunk/samples/font
This sample demonstrates wxGrid.

This sample demonstrates wxHtmlListBox.
Location: samples/htlbox subdirectory of your wxWidgets installation or http://svn.wxwidgets.org/viewvc/wx/wxWidgets/trunk/samples/htlbox
The image sample demonstrates use of the 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 two rectangles, one of which is drawn directly in the window, the other one is drawn into a 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 saving PNG files are tested.
At the bottom of the main frame there is a test for using a monochrome bitmap by drawing into a wxMemoryDC. The bitmap is then drawn specifying the foreground and background colours with wxDC::SetTextForeground() and wxDC::SetTextBackground() (on the left). The bitmap is then converted to a wxImage and the foreground colour (black) is replaced with red using wxImage::Replace().
This sample also contains the code for testing the image rotation and resizing and using raw bitmap access, see the corresponding menu commands.
Location: samples/image subdirectory of your wxWidgets installation or http://svn.wxwidgets.org/viewvc/wx/wxWidgets/trunk/samples/image
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 program messages into another language while true i18n would also involve changing the other aspects of the program's behaviour.
More information about this sample can be found in the readme.txt file in its directory. Please also see the Internationalization overview.

This sample demonstrates wxKeyEvent.
This sample can be used to interactively test the events produced by pressing various keyboard keys. It also shows the interaction between accelerators and the normal keyboard events (which are overridden by any defined accelerators) and finally allows to test that not skipping an event in EVT_KEY_DOWN handler suppresses the subsequent EVT_CHAR event.
Location: samples/keyboard subdirectory of your wxWidgets installation or http://svn.wxwidgets.org/viewvc/wx/wxWidgets/trunk/samples/keyboard
The layout sample demonstrates the two different layout systems offered by wxWidgets. 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 wxLayoutConstraints class. See also the overview and the wxIndividualLayoutConstraint class for further information.
The menu in this sample offers two more tests, one showing how to use a wxBoxSizer in a simple dialog and the other one showing how to use sizers in connection with a wxNotebook class. See also wxSizer.

This sample demonstrates wxScrolledWindow.
This sample demonstrates use of the wxScrolledWindow class including placing subwindows into it and drawing simple graphics. It uses the SetTargetWindow 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 wxWidgets, in particular using the wxWindow::IsExposed() method with the aim to prevent unnecessary drawing in the window and thus reducing or removing flicker on screen.
Location: samples/scroll subdirectory of your wxWidgets installation or http://svn.wxwidgets.org/viewvc/wx/wxWidgets/trunk/samples/scroll
This sample demonstrates how to implement a shaped or transparent window, and a window showing/hiding with effect.
Location: samples/shaped subdirectory of your wxWidgets installation or http://svn.wxwidgets.org/viewvc/wx/wxWidgets/trunk/samples/shaped
The sockets sample demonstrates how to use the communication facilities provided by wxSocket. There are two different applications in this sample: a server, which is implemented using a wxSocketServer object, and a client, which is implemented as a 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 (wxSOCKET_CONNECTION events), and sits there, waiting for clients (listening, in socket parlance). For each accepted connection, a new 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 wxSOCKET_INPUT (incoming data) or 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 GetSocket 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 wxSocketBase, such as wxSocketBase::Read(), wxSocketBase::Write(), wxSocketBase::ReadMsg() and wxSocketBase::WriteMsg(), 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 wxSOCKET_LOST events, each one is immediately notified if the other end closes the connection.
There is also a URL test which shows how to use the wxURL class to fetch data from a given URL.
The sockets sample is work in progress. Some things to do:
Location: samples/sockets subdirectory of your wxWidgets installation or http://svn.wxwidgets.org/viewvc/wx/wxWidgets/trunk/samples/sockets
The sound sample shows how to use wxSound for simple audio output (e.g. notifications).

This sample demonstrates wxSplitterWindow.
Location: samples/splitter subdirectory of your wxWidgets installation or http://svn.wxwidgets.org/viewvc/wx/wxWidgets/trunk/samples/splitter
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.
Location: samples/statbar subdirectory of your wxWidgets installation or http://svn.wxwidgets.org/viewvc/wx/wxWidgets/trunk/samples/statbar
This sample demonstrates wxStyledTextCtrl.

This sample demonstrates wxSVGFileDC.
Location: samples/svg subdirectory of your wxWidgets installation or http://svn.wxwidgets.org/viewvc/wx/wxWidgets/trunk/samples/svg
This sample allows to test keyboard navigation (mostly done using the TAB key, hence the sample name) between different controls. It shows the use of wxWindow::MoveBeforeInTabOrder() and MoveAfterInTabOrder() methods to change the default order of the windows in the navigation chain and of wxWindow::Navigate() for moving focus along this chain.
Location: samples/taborder subdirectory of your wxWidgets installation or http://svn.wxwidgets.org/viewvc/wx/wxWidgets/trunk/samples/taborder
This sample demonstrates wxTaskBarIcon.
Location: samples/taskbar subdirectory of your wxWidgets installation or http://svn.wxwidgets.org/viewvc/wx/wxWidgets/trunk/samples/taskbar
This sample demonstrates four features: firstly the use and many variants of the wxTextCtrl class (single line, multi line, read only, password, ignoring TAB, ignoring ENTER).
Secondly it shows how to intercept a wxKeyEvent in both the raw form using the EVT_KEY_UP and EVT_KEY_DOWN macros and the higher level from using the 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 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 but not least: some of the text controls have tooltips and the sample also shows how tooltips can be centrally disabled and their latency controlled.
Location: samples/text subdirectory of your wxWidgets installation or http://svn.wxwidgets.org/viewvc/wx/wxWidgets/trunk/samples/text
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 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, wxWidgets offers the wxQueueEvent function and this sample demonstrates its usage.
The other way is to use a wxMutexGuiEnter and wxMutexGuiLeave functions, but this is not currently shown in the sample.
See also Multithreading Overview and wxThread.
Location: samples/thread subdirectory of your wxWidgets installation or http://svn.wxwidgets.org/viewvc/wx/wxWidgets/trunk/samples/thread
The toolbar sample shows the wxToolBar class in action.
The following things are demonstrated:
EVT_UPDATE_UI handler for automatically enabling/disabling toolbar buttons without having to explicitly call EnableTool. This is done in MyFrame::OnUpdateCopyAndCut(). 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 adds 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 Ctrl-A) you will also 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.
Location: samples/toolbar subdirectory of your wxWidgets installation or http://svn.wxwidgets.org/viewvc/wx/wxWidgets/trunk/samples/toolbar
This sample demonstrates using the 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.
