11@page page_samples Included Samples
12
13Probably the best way to learn wxWidgets is by reading the source of some 80+
14samples provided with it. Many aspects of wxWidgets programming can be learnt
15from them, but sometimes it is not simple to just choose the right sample to
16look at. This overview aims at describing what each sample does/demonstrates to
17make it easier to find the relevant one if a simple grep through all sources
18didn't help. They also provide some notes about using the samples and what
19features of wxWidgets are they supposed to test.
20
21There are currently more than 80 different samples as part of wxWidgets:
22the list in this page is not complete!
23You should start your tour of wxWidgets with the @ref page_samples_minimal
24which is the wxWidgets version of "Hello, world!".
25It shows the basic structure of wxWidgets program and is the most commented
26sample of all - looking at its source code is recommended.
27
28The next most useful samples are probably @ref page_samples_widgets and
29@ref page_samples_controls which show many of wxWidgets native and
30generic controls, such as buttons, listboxes, checkboxes, comboboxes etc.
31
32Other, more complicated controls, have their own samples. In this category you
33may find the following samples showing the corresponding controls:
34
35@li wxCalendarCtrl: @ref page_samples_calendar
36@li wxListCtrl: @ref page_samples_listctrl
37@li wxTreeCtrl: @ref page_samples_treectrl
38@li wxGrid: @ref page_samples_grid
39@li wxDataViewCtrl: @ref page_samples_dataview
40
41Finally, it might be helpful to do a search in the entire sample directory if
42you can't find the sample showing the control you are interested in by
43name. Most classes contained in wxWidgets occur in at least one of the samples.

204
205This sample demonstrates the wxConfig classes in a platform
206independent way, i.e. it uses text based files to store a given configuration under
207Unix and uses the Registry under Windows.
208
209See @ref overview_config for the descriptions of all features of this class.

219@section page_samples_controls Controls Sample
220
221The controls sample is the main test program for most simple controls used in
222wxWidgets. The sample tests their basic functionality, events, placement,
223modification in terms of colour and font as well as the possibility to change
224the controls programmatically, such as adding an item to a list box etc. Apart
225from that, the sample uses a wxNotebook and tests most
226features of this special control (using bitmap in the tabs, using
227wxSizer instances and wxLayoutConstraints within notebook pages, advancing pages
228programmatically and vetoing a page change by intercepting the wxNotebookEvent.
229
230The various controls tested are listed here:
231

262@section page_samples_debugrpt Debug Reporter Sample
263
264This sample shows how to use wxDebugReport class to
265generate a debug report in case of a program crash or otherwise. On start up,
266it proposes to either crash itself (by dereferencing a NULL pointer) or
267generate debug report without doing it. Next it initializes the debug report
268with standard information adding a custom file to it (just a timestamp) and
269allows to view the information gathered using
270wxDebugReportPreview.
271
272For the report processing part of the sample to work you should make available
273a Web server accepting form uploads, otherwise
274wxDebugReportUpload will report an error.

280@section page_samples_dialogs Dialogs Sample
281
282This sample shows how to use the common dialogs available from wxWidgets. These
283dialogs are described in detail in the @ref overview_cmndlg.
284
285@sampledir{dialogs}
286
287@section page_samples_dialup Dialup Sample
288
289This sample shows the wxDialUpManager
290class. In the status bar, it displays the information gathered through its
291interface: in particular, the current connection status (online or offline) and
292whether the connection is permanent (in which case a string `LAN' appears in
293the third status bar field - but note that you may be on a LAN not
294connected to the Internet, in which case you will not see this) or not.
295
296Using the menu entries, you may also dial or hang up the line if you have a
297modem attached and (this only makes sense for Windows) list the available
298connections.

307
308@section page_samples_dnd Drag & Drop Sample
309
310This sample shows both clipboard and drag and drop in action. It is quite non
311trivial and may be safely used as a basis for implementing the clipboard and
312drag and drop operations in a real-life program.
313
314When you run the sample, its screen is split in several parts. On the top,
315there are two listboxes which show the standard derivations of
316wxDropTarget:
317wxTextDropTarget and
318wxFileDropTarget.
319
320The middle of the sample window is taken by the log window which shows what is
321going on (of course, this only works in debug builds) and may be helpful to see
322the sequence of steps of data transfer.
323
324Finally, the last part is used for dragging text from it to either one of the
325listboxes (only one will accept it) or another application. The last
326functionality available from the main frame is to paste a bitmap from the
327clipboard (or, in the case of the Windows version, also a metafile) - it will be
328shown in a new frame.
329
330So far, everything we mentioned was implemented with minimal amount of code
331using standard wxWidgets classes. The more advanced features are demonstrated
332if you create a shape frame from the main frame menu. A shape is a geometric
333object which has a position, size and color. It models some
334application-specific data in this sample. A shape object supports its own
335private wxDataFormat which means that you may cut and
336paste it or drag and drop (between one and the same or different shapes) from
337one sample instance to another (or the same). However, chances are that no
338other program supports this format and so shapes can also be rendered as
339bitmaps which allows them to be pasted/dropped in many other applications
340(and, under Windows, also as metafiles which are supported by most of Windows
341programs as well - try Write/Wordpad, for example).
342
343Take a look at DnDShapeDataObject class to see how you may use
344wxDataObject to achieve this.

373
374@section page_samples_event Event Sample
375
376This sample demonstrates various features of the wxWidgets events. It
377shows how to dynamic events and connecting/disconnecting the event handlers
378during run time by using wxEvtHandler::Connect() and wxEvtHandler::Disconnect(),
379and also how to use wxWindow::PushEventHandler() and wxWindow::PopEventHandler().
380
381@sampledir{event}
382
383@section page_samples_except Exception Sample
384
385This very simple sample shows how to use C++ exceptions in wxWidgets programs,
386i.e. where to catch the exception which may be thrown by the program code. It
387doesn't do anything very exciting by itself, you need to study its code to
388understand what goes on.
389
390<b>Build Note:</b>
391You need to build the library with @c wxUSE_EXCEPTIONS being set to @c 1
392and compile your code with C++ exceptions support to be able to build this
393sample.
394
395@sampledir{except}
396
397@section page_samples_exec External Program Execution Sample
398
399The exec sample demonstrates the wxExecute and
400wxShell functions. Both of them are used to execute the
401external programs and the sample shows how to do this synchronously (waiting
402until the program terminates) or asynchronously (notification will come later).
403
404It also shows how to capture the output of the child process in both
405synchronous and asynchronous cases and how to kill the processes with
406wxProcess::Kill() and test for their existence with
407wxProcess::Exists().
408
409@sampledir{exec}
410
411@section page_samples_flash Flash Sample
412
413The flash sample demonstrates embedding of Adobe Flash into a wxWidgets
414program. Currently it only works under Windows as it uses the Flash ActiveX
415control to achieve this but we hope to be able to extend it to also work under
416other platforms in the future. The sample also currently requires Microsoft
417Visual C++ compiler as it uses COM support extensions specific to this
418compiler.
419
420The sample comes with 2 Flash files (SWF), showing a simple Flash animation
421which can be controlled using the "Play", "Stop" and "Back"/"Forward" buttons
422in the sample as well as a Flash form which shows how Flash and wxWidgets
423program can exchange data: calling "GetText" function without arguments returns
424the text of the text control defined inside Flash and calling "SetText" with an
425argument sets the control contents to the given string. Finally clicking on the
426button generates an event which is caught by the C++ program.
427
428@section page_samples_font Font Sample
429
430The font sample demonstrates wxFont,
431wxFontEnumerator and
432wxFontMapper classes. It allows you to see the fonts
433available (to wxWidgets) on the computer and shows all characters of the
434chosen font as well.

449
450@section page_samples_html HTML Sample
451
452Eight HTML samples cover all features of the HTML sub-library.
453
454@li @b Test demonstrates how to create wxHtmlWindow
455and also shows most supported HTML tags.
456
457@li @b Widget shows how you can embed ordinary controls or windows within an
458HTML page. It also nicely explains how to write new tag handlers and extend
459the library to work with unsupported tags.
460
461@li @b About may give you an idea how to write good-looking About boxes.
462
463@li @b Zip demonstrates use of virtual file systems in wxHTML. The zip archives
464handler (ships with wxWidgets) allows you to access HTML pages stored
465in a compressed archive as if they were ordinary files.
466
467@li @b Virtual is yet another virtual file systems demo. This one generates pages at run-time.
468You may find it useful if you need to display some reports in your application.
469
470@li @b Printing explains use of wxHtmlEasyPrinting
471class which serves as as-simple-as-possible interface for printing HTML
472documents without much work. In fact, only few function calls are sufficient.
473
474@li @b Help and @b Helpview are variations on displaying HTML help
475(compatible with MS HTML Help Workshop). @e Help shows how to embed
476wxHtmlHelpController in your application
477while @e Helpview is a simple tool that only pops up the help window and
478displays help books given at command line.

487
488@section page_samples_image Image Sample
489
490The image sample demonstrates use of the wxImage class
491and shows how to download images in a variety of formats, currently PNG, GIF,
492TIFF, JPEG, BMP, PNM and PCX. The top of the sample shows two rectangles, one
493of which is drawn directly in the window, the other one is drawn into a
494wxBitmap, converted to a wxImage, saved as a PNG image
495and then reloaded from the PNG file again so that conversions between wxImage
496and wxBitmap as well as loading and saving PNG files are tested.
497
498At the bottom of the main frame there is a test for using a monochrome bitmap by
499drawing into a wxMemoryDC. The bitmap is then drawn
500specifying the foreground and background colours with
501wxDC::SetTextForeground() and
502wxDC::SetTextBackground() (on the left). The
503bitmap is then converted to a wxImage and the foreground colour (black) is
504replaced with red using wxImage::Replace().
505
506This sample also contains the code for testing the image rotation and resizing
507and using raw bitmap access, see the corresponding menu commands.
508
509@sampledir{image}
510
511@section page_samples_internat Internationalization Sample
512
513The not very clearly named internat sample demonstrates the wxWidgets
514internationalization (i18n for short from now on) features. To be more
515precise, it only shows localization support, i.e. support for translating the
516program messages into another language while true i18n would also involve
517changing the other aspects of the programs behaviour.
518
519More information about this sample can be found in the @c readme.txt file in
520its directory. Please also see the @ref overview_i18n.

543
544The layout sample demonstrates the two different layout systems offered
545by wxWidgets. When starting the program, you will see a frame with some
546controls and some graphics. The controls will change their size whenever
547you resize the entire frame and the exact behaviour of the size changes
548is determined using the wxLayoutConstraints
549class. See also the overview and the
550wxIndividualLayoutConstraint
551class for further information.
552
553The menu in this sample offers two more tests, one showing how to use
554a wxBoxSizer in a simple dialog and the other one
555showing how to use sizers in connection with a wxNotebook
556class. See also wxSizer.

564the menu.
565
566The sample also provides some timings for adding/deleting/sorting a lot of

618i.e. a minimal program that doesn't demonstrate anything apart from what is
619needed to write a program that will display a "hello" dialog. This is usually
620a good starting point for learning how to use wxWidgets.

742This sample demonstrates use of the ::wxScrolledWindow
743class including placing subwindows into it and drawing simple graphics. It uses
744the SetTargetWindow method and thus the effect of scrolling does not show in
745the scrolled window itself, but in one of its subwindows.
746
747Additionally, this samples demonstrates how to optimize drawing operations in
748wxWidgets, in particular using the wxWindow::IsExposed() method with the aim to
749prevent unnecessary drawing in the window and thus reducing or removing flicker
750on screen.

763@section page_samples_sockets Sockets Sample
764
765The sockets sample demonstrates how to use the communication facilities
766provided by wxSocket. There are two different
767applications in this sample: a server, which is implemented using a
768wxSocketServer object, and a client, which
769is implemented as a wxSocketClient.
770
771The server binds to the local address, using TCP port number 3000,
772sets up an event handler to be notified of incoming connection requests
773(@b wxSOCKET_CONNECTION events), and sits there, waiting for clients
774(@e listening, in socket parlance). For each accepted connection,
775a new wxSocketBase object is created. These
776socket objects are independent from the server that created them, so
777they set up their own event handler, and then request to be notified
778of @b wxSOCKET_INPUT (incoming data) or @b wxSOCKET_LOST
779(connection closed at the remote end) events. In the sample, the event
780handler is the same for all connections; to find out which socket the
781event is addressed to, the GetSocket function
782is used.
783
784Although it might take some time to get used to the event-oriented
785system upon which wxSocket is built, the benefits are many. See, for
786example, that the server application, while being single-threaded
787(and of course without using fork() or ugly select() loops) can handle
788an arbitrary number of connections.
789
790The client starts up unconnected, so you can use the Connect... option
791to specify the address of the server you are going to connect to (the
792TCP port number is hard-coded as 3000). Once connected, a number of
793tests are possible. Currently, three tests are implemented. They show
794how to use the basic IO calls in wxSocketBase,
795such as wxSocketBase::Read(), wxSocketBase::Write(),
796wxSocketBase::ReadMsg() and wxSocketBase::WriteMsg(),
797and how to set up the correct IO flags depending on what you are going to
798do. See the comments in the code for more information. Note that because
799both clients and connection objects in the server set up an event handler
800to catch @b wxSOCKET_LOST events, each one is immediately notified
801if the other end closes the connection.
802
803There is also a URL test which shows how to use
804the wxURL class to fetch data from a given URL.
805
806The sockets sample is work in progress. Some things to do:
807
808@li More tests for basic socket functionality.
809@li More tests for protocol classes (wxProtocol and its descendants).
810@li Tests for the recently added (and still in alpha stage) datagram sockets.
811@li New samples which actually do something useful (suggestions accepted).

835
836This sample shows how to create and use wxStatusBar. Although most of the
837samples have a statusbar, they usually only create a default one and only
838do it once.
839
840Here you can see how to recreate the statusbar (with possibly different number
841of fields) and how to use it to show icons/bitmaps and/or put arbitrary
842controls into it.

859
860This sample allows to test keyboard navigation (mostly done using the
861@c TAB key, hence the sample name) between different controls.
862It shows the use of wxWindow::MoveBeforeInTabOrder() and
863MoveAfterInTabOrder() methods to change
864the default order of the windows in the navigation chain and of
865wxWindow::Navigate() for moving focus along this
866chain.

876@section page_samples_text Text Sample
877
878This sample demonstrates four features: firstly the use and many variants of
879the wxTextCtrl class (single line, multi line, read only,
880password, ignoring TAB, ignoring ENTER).
881
882Secondly it shows how to intercept a wxKeyEvent in both
883the raw form using the @c EVT_KEY_UP and @c EVT_KEY_DOWN macros and the
884higher level from using the @c EVT_CHAR macro. All characters will be logged
885in a log window at the bottom of the main window. By pressing some of the function
886keys, you can test some actions in the text ctrl as well as get statistics on the
887text ctrls, which is useful for testing if these statistics actually are correct.
888
889Thirdly, on platforms which support it, the sample will offer to copy text to the
890wxClipboard and to paste text from it. The GTK version will
891use the so called PRIMARY SELECTION, which is the pseudo clipboard under X and
892best known from pasting text to the XTerm program.
893
894Last not least: some of the text controls have tooltips and the sample also shows
895how tooltips can be centrally disabled and their latency controlled.

898
899@section page_samples_thread Thread Sample
900
901This sample demonstrates use of threads in connection with GUI programs.
902
903There are two fundamentally different ways to use threads in GUI programs and
904either way has to take care of the fact that the GUI library itself usually
905is not multi-threading safe, i.e. that it might crash if two threads try to
906access the GUI class simultaneously.
907
908One way to prevent that is have a normal GUI program in the main thread and some
909worker threads which work in the background. In order to make communication between
910the main thread and the worker threads possible, wxWidgets offers the ::wxQueueEvent
911function and this sample demonstrates its usage.
912
913The other way is to use a ::wxMutexGuiEnter and ::wxMutexGuiLeave functions, but
914this is not currently shown in the sample.
915
916See also @ref overview_thread and wxThread.

919
920@section page_samples_toolbar Tool Bar Sample
921
922The toolbar sample shows the wxToolBar class in action.
923
924The following things are demonstrated:
925
926@li Creating the toolbar using wxToolBar::AddTool() and wxToolBar::AddControl(): see
927 MyApp::InitToolbar() in the sample.
928@li Using @c EVT_UPDATE_UI handler for automatically enabling/disabling
929 toolbar buttons without having to explicitly call EnableTool. This is done
930 in MyFrame::OnUpdateCopyAndCut().
931@li Using wxToolBar::DeleteTool() and wxToolBar::InsertTool() to dynamically update the
932 toolbar.
933
934Some buttons in the main toolbar are check buttons, i.e. they stay checked when
935pressed. On the platforms which support it, the sample also adds a combobox
936to the toolbar showing how you can use arbitrary controls and not only buttons
937in it.
938
939If you toggle another toolbar in the sample (using @c Ctrl-A) you will also
940see the radio toolbar buttons in action: the first three buttons form a radio
941group, i.e. checking any of them automatically unchecks the previously
942checked one.
943
944@sampledir{toolbar}
945
946@section page_samples_treectrl wxTreeCtrl Sample
947
948This sample demonstrates using the wxTreeCtrl class. Here
949you may see how to process various notification messages sent by this control
950and also when they occur (by looking at the messages in the text control in
951the bottom part of the frame).
952
953Adding, inserting and deleting items and branches from the tree as well as
954sorting (in default alphabetical order as well as in custom one) is
955demonstrated here as well - try the corresponding menu entries.

984The sample tests their basic functionality, events, placement, modification
985in terms of colour and font as well as the possibility to change
986the controls programmatically, such as adding an item to a list box etc.
987All widgets are categorized for easy browsing.

991@section page_samples_wizard Wizard Sample
992
993This sample shows the so-called wizard dialog (implemented using
994wxWizard and related classes). It shows almost all
995features supported:
996
997@li Using bitmaps with the wizard and changing them depending on the page
998 shown (notice that wxValidationPage in the sample has a different image from
999 the other ones)
1000@li Using TransferDataFromWindow
1001 to verify that the data entered is correct before passing to the next page
1002 (done in wxValidationPage which forces the user to check a checkbox before
1003 continuing).
1004@li Using more elaborated techniques to allow returning to the previous
1005 page, but not continuing to the next one or vice versa (in wxRadioboxPage)
1006@li This (wxRadioboxPage) page also shows how the page may process the
1007 @e Cancel button itself instead of relying on the wizard parent to do it.
1008@li Normally, the order of the pages in the wizard is known at compile-time,
1009 but sometimes it depends on the user choices: wxCheckboxPage shows how to
1010 dynamically decide which page to display next (see also
1011 wxWizardPage)
