Arguably the best way to learn wxWidgets is by reading the sources of many samples, or examples, provided with it.
Many aspects of wxWidgets programming can be learned 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.
Notice that all wxWidgets samples mentioned here 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 https://github.com/wxWidgets/wxWidgets/tree/master/samples/ but you need to download the source distribution in order to be able to build them (highly recommended).
Although reading the samples code can be very useful, it may not be sufficient and often it is even more useful to experiment by making a small change to a sample and checking how it works when running the sample.
Before being able to run them, you need to be able build the sample you're interested in. The right way to do it depends on the way you built wxWidgets itself (see Installing wxWidgets for more details):
makefile.vc
from the directory of the sample to build it. Open "Developer Command Prompt", navigate to the sample directory and run nmake -f makefile.vc
command with the additional arguments corresponding to your library build, e.g. BUILD=debug
. See MSVS instructions for more information.makefile.gcc
in the sample directory in a similar way. Note that if you use MSYS2 or another Unix-like environment for building, you should use the Unix instructions below instead.makefile.unx
in the sample directory to build it using the version of wxWidgets already installed on your system. Use make -f makefile.unx
in the sample directory to build it.Makefile
in the directory with the same name as the sample directory, but under the build directory, i.e. the one where you ran configure, and not under the source directory. Just run make
to build the sample in the build directory subdirectory, e.g. ~/build/wx/samples/minimal
. You can also build all the samples at once by doing make samples
, but be warned that this might take some time on older and slower machines.There are currently almost 100 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:
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.

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 nullptr) 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

This sample demonstrates wxDisplay.
Location: samples/display
subdirectory of your wxWidgets installation or https://github.com/wxWidgets/wxWidgets/tree/master/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.

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.

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.

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:

This sample demonstrates wxTaskBarIcon.
Location: samples/taskbar
subdirectory of your wxWidgets installation or https://github.com/wxWidgets/wxWidgets/tree/master/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.

subdirectory of your wxWidgets installation or https://github.com/wxWidgets/wxWidgets/tree/master/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.

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
