36 | <H2 CLASS="western">The Wonderful World of wxWidgets 3.0</H2> | |
37 | <H3 CLASS="western">What is wxWidgets?</H3> | |
38 | <P ALIGN=JUSTIFY>Although it is quite unlikely that you'll read this | |
39 | document if you don't know what wxWidgets is, let's just briefly | |
40 | mention that wxWidgets is a C++ framework for building rich GUI | |
41 | applications from a single source which can then be compiled on | |
42 | different operating systems, resulting in a native application on | |
43 | each system. wxWidgets uses native controls (or widgets) and other | |
44 | native functions whereever possible so that the resulting | |
45 | applications will look and feel as native as possible, and they are | |
46 | usually not distinguishable from applications written using single | |
47 | platform toolkits such as MFC for Windows, GTK+ for Linux or Cocoa | |
48 | under OS X. In some areas (such as graphics art or the installer), | |
49 | adaptations to the individual platforms have to be made in order to | |
50 | achieve perfect integration with that platform.</P> | |
51 | <P ALIGN=JUSTIFY>The major operating system for which wxWidgets | |
52 | supports are Windows (Windows 95, NT, 2000, XP, Vista) including its | |
53 | mobile variants (Windows CE, PocketPC, Windows Mobile), Linux and | |
54 | Unix using the GTK+ 2 toolkit (minimum version is GTK+ 2.4, more | |
55 | recent features are used when available) and Mac OS X (minimum | |
56 | version 10.4 Tiger, both Intel, PPC and the Universal Binaries for | |
57 | both are supported). wxWidgets includes many code pieces for | |
58 | optimising dialog and general layout for small screens such as those | |
59 | of the recent netbooks and mobile phones and tablets.</P> | |
60 | <P ALIGN=JUSTIFY>There is varying support for other platforms or | |
61 | toolkits such as OS/2, Motif, GTK 1.2, PalmOS and various mobile | |
62 | Linux variants using GTK+ or the Hildon framework and also a version | |
63 | for OS X using the Cocoa API and even the iPhone SDK.</P> | |
64 | <H3 CLASS="western">Documentation in Doxygen</H3> | |
65 | <P ALIGN=JUSTIFY STYLE="margin-bottom: 0cm">Until wxWidgets 3.0 all | |
66 | documentation was written in a customized LaTeX variant created for | |
67 | the project years ago. Although there were tools which could parse | |
68 | classes automatically and create a documentation skeleton, class | |
69 | documentation was troublesome to update and therefore often outdated. | |
70 | In order to improve this situation, the entire documentation | |
71 | including references and overviews was converted to a customized | |
72 | Doxygen format inlined in a special set of headers. Although many | |
73 | classes were converted in a single automated step, every class | |
74 | documentation had to be corrected by hand making this effort one of | |
75 | the biggest in the development cycle leading up wxWidgets 3.0. | |
76 | Additionally, tools were written to automatically compare the | |
77 | signature of the many class methods to the documentation. The result | |
78 | is more correct documentation with better formating and built-in | |
79 | searching and screenshots of many controls. Since Doxygen is a | |
80 | wide-spread format and easy to learn, the new documentation is much | |
81 | easier to edit, correct and read. See the <A HREF="http://docs.wxwidgets.org/trunk/index.html">wxWidgets | |
82 | on-line documentation</A> to which this document refers to in many | |
83 | places.</P> | |
84 | <H3 CLASS="western">C++ features and template support</H3> | |
85 | <P ALIGN=JUSTIFY STYLE="margin-bottom: 0cm">The wxWidgets project | |
86 | tries to both move with new developments of the C++ language as well | |
87 | as to support older compilers to an extent which does not inhibit | |
88 | further development and indeed the usefulness of the entire project. | |
89 | Since support for templates used to be limited to a few compilers and | |
90 | was often buggy even in them, wxWidgets initially stayed away from | |
91 | using templates entirely including the use of the Standard Template | |
92 | Library (STL). In the meantime nearly all compilers have gained solid | |
93 | template support and therefore wxWidgets is now using templates for | |
94 | container classes (such as <A HREF="http://docs.wxwidgets.org/trunk/classwx_vector_3_01_t_01_4.html">wxVector<T></A>), | |
95 | smart pointers (such as <A HREF="http://docs.wxwidgets.org/trunk/classwx_shared_ptr_3_01_t_01_4.html">wxSharedPtr<T></A>), | |
96 | weak references (see <A HREF="http://docs.wxwidgets.org/trunk/classwx_weak_ref_3_01_t_01_4.html">wxWeakRef<T></A>) | |
97 | and many other places where templates are useful. This means that | |
98 | very old compilers won't be able to compile wxWidgets anymore or only | |
99 | in a degraded way (such as Visual C++ 6.0).</P> | |
100 | <H3 CLASS="western">Platform features and backwards compatibility</H3> | |
101 | <P ALIGN=JUSTIFY STYLE="margin-bottom: 0cm">In the same way wxWidgets | |
102 | tries to both make use of new features of the different operating | |
103 | systems and support older systems for as long as possible and as long | |
104 | as supporting them does not hinder development for up-to-date | |
105 | systems. This is especially true for OS X and GTK+ 2 and it was | |
106 | therefore decided that OS X versions older than 10.4 Tiger and GTK+ 2 | |
107 | version older than 2.4 are no longer supported. The wxWidgets team | |
108 | also realized that it could not do everything and that support for a | |
109 | cross-platform database API was beyond the scope and focus of the | |
110 | project so that its old wxODBC database connectivity classes were | |
111 | removed from the project. There are many cross-platform database | |
112 | libraries available and many of them are better than the old wxODBC | |
113 | and all of them are better maintained.</P> | |
114 | <H3 CLASS="western">Unicode: A Single Build for Everyone</H3> | |
115 | <P ALIGN=JUSTIFY STYLE="margin-bottom: 0cm">Until version 3.0 there | |
116 | have always been two different versions (or builds) of wxWidgets: one | |
117 | with full support for Unicode where each character was represented by | |
118 | a wchar_t internally (using two bytes under Windows and four bytes | |
119 | almost everywhere else) and another called the „ANSI“ build where | |
120 | each character was represented by a single byte. This model was | |
121 | chosen following the original Windows API model and at a point of | |
122 | time when Unicode support was hardly present anywhere else. In the | |
123 | meantime, the Windows world together with projects such as Java have | |
124 | chosen UTF-16 as the native representation for Unicode strings | |
125 | whereas much of the free software world including GTK+ and parts of | |
126 | Mac OS X have chosen UTF-8. It was therefore decided to drastically | |
127 | change the implementation of wxWidgets' string class and make it use | |
128 | UTF-16 under Windows (mostly as before) but UTF-8 elsewhere (instead | |
129 | of wide character strings using wchar_t) so that strings received | |
130 | from and sent to Unix and GTK+ library calls would no longer have to | |
131 | be converted back and forth between different Unicode representations | |
132 | (see <A HREF="http://docs.wxwidgets.org/trunk/classwx_string.html">wxString</A> | |
133 | and <A HREF="http://docs.wxwidgets.org/trunk/overview_unicode.html">Unicode | |
134 | overview</A>). Additionally, the „ANSI“ mode was removed and the | |
135 | wxString class as well as some other classes were modified to accept | |
136 | and return both Unicode and 8-bit string literals if required. The | |
137 | same was done to functions like wxPrintf() etc. Although this change | |
138 | will eventually not be seen by the end user of an application written | |
139 | using wxWidgets, it is such a fundamental change that it was the | |
140 | primary reason to give wxWidgets the new major version number 3.</P> | |
141 | <H3 CLASS="western">New 2D Drawing Code</H3> | |
142 | <P ALIGN=JUSTIFY STYLE="margin-bottom: 0cm">Although a 2D drawing API | |
143 | has always been part of wxWidgets (using so-called device contexts | |
144 | such as a window or a bitmap and pens and brushes to draw into them, | |
145 | see <A HREF="http://docs.wxwidgets.org/trunk/classwx_d_c.html">wxDC</A>, | |
146 | <A HREF="http://docs.wxwidgets.org/trunk/classwx_pen.html">wxPen</A>, | |
147 | <A HREF="http://docs.wxwidgets.org/trunk/classwx_brush.html">wxBrush</A>), | |
148 | it has not changed much since its initial inception and so the code | |
149 | was completely reorganized using a single set of frontend classes and | |
150 | different backends which will make maintainance much easier without | |
151 | having to care for binary backwards compatibility and it also helped | |
152 | isolate a number of subtle platform differences. The old drawing API | |
153 | is good enough for many tasks and reflects the drawing capabilites of | |
154 | the 1990's but it didn't make use of advanced features such as | |
155 | transparency, anti-aliasing and free matrix transforms of modern 2D | |
156 | graphics systems such as GDI+ on Windows, Cairo on Linux (and | |
157 | elsewhere) and CoreGraphics on OS X. Therefore a completely new | |
158 | drawing API (the so called graphics contexts, see <A HREF="http://docs.wxwidgets.org/trunk/classwx_graphics_context.html">wxGraphicsContext</A>) | |
159 | was added to wxWidgets making use of modern drawing engines. This is | |
160 | complemented by a bitmap class with alpha channel support and fast | |
161 | raw access to the bitmap's internal data representation. Additionally | |
162 | the API of all existing GDI class constants was corrected so that | |
163 | wxMODERN becomes wxFONTFAMILY_MODERN, wxSOLID becomes | |
164 | wxBRUSHSTYLE_SOLID etc. and the reference counting system was | |
165 | streamlined and made identical on all platforms.</P> | |
166 | <H3 CLASS="western">Changes to wxBase</H3> | |
167 | <P ALIGN=JUSTIFY>wxBase is the name of the non-GUI part of wxWidgets | |
168 | libary which provides basic class such as the aforementioned wxString | |
169 | class, container classes, as well as classes for threading, | |
170 | networking, XML parsing, path and configuration management, logging, | |
171 | debugging etc. These functions and classes have been separated into | |
172 | their own library both for being able to write non-GUI apps as well | |
173 | as to make maintainance easier through reduced interdependence. | |
174 | </P> | |
175 | <P ALIGN=JUSTIFY>Many of the changes to wxString and the container | |
176 | classes are located in wxBase, but on top of that support to wxBase | |
177 | was added for events loops, timers and sockets for writing | |
178 | event-based client or server apps with wxWidgets 3.0. The socket code | |
179 | itself has been reorganized removing a lot of duplicated code and | |
180 | dropping the previous implementation which was separated into a C and | |
181 | a C++ part.</P> | |
182 | <H3 CLASS="western">New controls and other major GUI additions for | |
183 | all ports</H3> | |
184 | <P ALIGN=JUSTIFY>This document cannot list every bug fix and minor | |
185 | change. Rather, this paragraph summarizes the most relevant changes | |
186 | to the GUI classes of wxWidgets. Given wxWidgets' nature as a GUI | |
187 | library, these changes are also most likely to be visible to the user | |
188 | and may thus be the most important changes from a user's perspective | |
189 | (although not necessarily from a developer's perspective): | |
190 | </P> | |
191 | <UL> | |
192 | <LI><P ALIGN=JUSTIFY>wxDataViewCtrl and wxDataViewTreeCtrl: this | |
193 | control can partially replace both wxListCtrl and wxTreeCtrl (for | |
194 | which there only was a native version of Windows and partially for | |
195 | OS X) but also extends and combines the classes by being able to | |
196 | display a hierarchy and list at the same time and by offering a much | |
197 | more flexible way to display and edit data on a per column basis. | |
198 | Reimplementing wxTreeCtrl and possibly wxListCtrl in terms of | |
199 | wxDataViewCtrl was considered, but this was dropped as certain | |
200 | special features are not available on all platforms (or | |
201 | differently). See also <A HREF="http://docs.wxwidgets.org/trunk/classwx_data_view_ctrl.html">wxDataViewCtrl</A>, | |
202 | <A HREF="http://docs.wxwidgets.org/trunk/classwx_data_view_list_ctrl.html">wxDataViewListCtrl</A> | |
203 | and <A HREF="http://docs.wxwidgets.org/trunk/classwx_data_view_tree_ctrl.html">wxDataViewTreeCtrl</A>.</P> | |
204 | <LI><P ALIGN=JUSTIFY>The tabular view of wxGrid has been improved | |
205 | including a native header control, which has been separated into a | |
206 | new control. See also <A HREF="http://docs.wxwidgets.org/trunk/classwx_grid.html">wxGrid</A> | |
207 | and <A HREF="http://docs.wxwidgets.org/trunk/classwx_header_ctrl.html">wxHeaderCtrl.</A></P> | |
208 | <LI><P ALIGN=JUSTIFY>Added wxPropertyGrid which is a big generic | |
209 | control used to display lists and hierarchies of name-value pairs. | |
210 | Like wxDataViewCtrl, it offers a number of ready-to-use editors for | |
211 | editing text, numbers, lists, fonts, file names etc. using in-place | |
212 | editing or using pop-up dialog and combo boxes. Developement of | |
213 | wxPropertyGrid has so far taken place outside of wxWidgets as a | |
214 | separate project, but it has not been included in wxWidgets per se. | |
215 | See also <A HREF="http://docs.wxwidgets.org/trunk/classwx_property_grid.html">wxPropertyGrid</A>.</P> | |
216 | <LI><P ALIGN=JUSTIFY>wxHyperlinkCtrl added, implemented natively | |
217 | under GTK+ and in a generic way on other platforms. It can be used | |
218 | to represent a hypertext link, for example to the homepage of the | |
219 | developer or company. See also <A HREF="http://docs.wxwidgets.org/trunk/classwx_hyperlink_ctrl.html">wxHyperlinkCtrl</A>.</P> | |
220 | <LI><P ALIGN=JUSTIFY>wxFileCtrl for constructing fully customized | |
221 | file dialogs. Complementary to this, the possibility to add custom | |
222 | control to wxFileDialog has been added. See <A HREF="http://docs.wxwidgets.org/trunk/classwx_file_ctrl.html">wxFileCtrl</A> | |
223 | and <A HREF="http://docs.wxwidgets.org/trunk/classwx_file_dialog.html">wxFileDialog</A>.</P> | |
224 | <LI><P ALIGN=JUSTIFY>Several enhancements to wxRichTextCtrl | |
225 | including support for super- and subscript and many speed-ups. See | |
226 | <A HREF="http://docs.wxwidgets.org/trunk/classwx_rich_text_ctrl.html">wxRichTextCtrl</A>.</P> | |
227 | <LI><P ALIGN=JUSTIFY>The possibility to display state icons has been | |
228 | added to wxTreeCtrl. This can also be used to implement check-box | |
229 | like behaviour. See <A HREF="http://docs.wxwidgets.org/trunk/classwx_tree_ctrl.html">wxTreeCtrl</A>.</P> | |
230 | <LI><P ALIGN=JUSTIFY>wxCalendarCtrl has been rewritten using native | |
231 | code under MSW and GTK+ and enhanced in many ways (for example | |
232 | displaying week numbers). See <A HREF="http://docs.wxwidgets.org/trunk/classwx_calendar_ctrl.html">wxCalendarCtrl</A>.</P> | |
233 | <LI><P ALIGN=JUSTIFY>Implemented support for auto-completion for | |
234 | wxTextCtrl and wxComboBox.</P> | |
235 | <LI><P ALIGN=JUSTIFY>Added wxAUIToolBar to the set of wxAUI classes, | |
236 | which is better integrated and more flexible than the standard | |
237 | wxToolBar.</P> | |
238 | <LI><P ALIGN=JUSTIFY>Reimplemented wxBitmapComboBox using native | |
239 | code under MSW and GTK+. See also <A HREF="http://docs.wxwidgets.org/trunk/classwx_bitmap_combo_box.html">wxBitmapComboBox</A>.</P> | |
240 | <LI><P ALIGN=JUSTIFY>Added wxBitmapToggleButton on all platforms. | |
241 | See also <A HREF="http://docs.wxwidgets.org/trunk/classwx_bitmap_toggle_button.html">wxBitmapToggleButton</A>.</P> | |
242 | <LI><P ALIGN=JUSTIFY>Added support for ellipsization on all | |
243 | platforms and for mark-up formatting under GTK+ to wxStaticText. See | |
244 | <A HREF="http://docs.wxwidgets.org/trunk/classwx_static_text.html">wxStaticText</A>.</P> | |
245 | <LI><P ALIGN=JUSTIFY>Rewritten the selection event emission logic of | |
246 | wxListBox on all platforms to more exactly match each other when | |
247 | selecting and deselecting certain items.</P> | |
248 | <LI><P ALIGN=JUSTIFY>Implemented wxCollapsiblePane natively for GTK | |
249 | and OS X. See <A HREF="http://docs.wxwidgets.org/trunk/classwx_collapsible_pane.html">wxCollapsiblePane</A>.</P> | |
250 | <LI><P ALIGN=JUSTIFY>Added a new sizer which can wrap across | |
251 | multiple lines. See <A HREF="http://docs.wxwidgets.org/trunk/classwx_wrap_sizer.html">wxWrapSizer</A>.</P> | |
252 | <LI><P ALIGN=JUSTIFY>Added multi-sample and anti-aliasing support | |
253 | the the OpenGL canvas and separated wxGLCanvas and wxGLContext. See | |
254 | <A HREF="http://docs.wxwidgets.org/trunk/classwx_g_l_canvas.html">wxGLCanvas</A>.</P> | |
255 | <LI><P ALIGN=JUSTIFY>Added wxNativeContainerWindow in order to | |
256 | construct a wxTopLevelWindow from a native window handle (MSW and | |
257 | GTK+).</P> | |
258 | <LI><P ALIGN=JUSTIFY>The <A HREF="http://docs.wxwidgets.org/trunk/classwx_v_scrolled_window.html">wxVScrolledWindow</A> | |
259 | class has been completely rewritten to accommodate the addition of | |
260 | the new horizontal scrolling variants (<A HREF="http://docs.wxwidgets.org/trunk/classwx_h_scrolled_window.html">wxHScrolledWindow</A> | |
261 | and <A HREF="http://docs.wxwidgets.org/trunk/classwx_h_v_scrolled_window.html">wxHVScrolledWindow</A>) | |
262 | while still providing complete backwards compatibility for | |
263 | wxVScrolledWindow.</P> | |
264 | </UL> | |
265 | <H3 CLASS="western">wxMac specific changes (now called wxOSX)</H3> | |
266 | <P ALIGN=JUSTIFY>One important change of the wxMac port is that the | |
267 | port is not called wxMac anymore. Instead, the more appropriate term | |
268 | wxOSX should be used as the operating system is called OS X nowadays | |
269 | and – more importantly – wxWidgets now has partial support for | |
270 | iPhone and iPod, and these are devices are clearly not Macs. Apart | |
271 | from the name change – wxMac has undergone the most fundamental | |
272 | changes of the three main ports, even if some of the changes were | |
273 | mostly reorganizing code instead of writing new code. The code has | |
274 | been reorganized into common code (common to Carbon, Cocoa and Cocoa | |
275 | Touch) including both general wrapping or front-end classes for much | |
276 | of the GUI code as well as a wrapper for the so called CoreFoundation | |
277 | classes of OS X, which are responsible on all OS X variants for | |
278 | string manipulation, font support, graphics and other basic | |
279 | functionality (CoreImage and CoreVideo have recently been added by | |
280 | Apple) and toolkit dependent code for the Carbon, Cocoa and Cocoa | |
281 | Touch API. The Carbon variant is the core of what used to be wxMac | |
282 | and is the most stable and mature version. The reason behind adding | |
283 | optional support for Cocoa and Cocoa Touch is that Carbon is not | |
284 | available on iPhones at all and that it has been deprecated for all | |
285 | 64-bit versions of OS X, which is likely to be the default a few | |
286 | years from now. So while present applications using wxOSX are advised | |
287 | to use the Carbon backend due its maturity, future developement will | |
288 | have to focus on the Cocoa backend.</P> | |
289 | <P ALIGN=JUSTIFY>As part of the restructuring, all remaining drawing | |
290 | code using the old QuickDraw API has been removed (it was only an | |
291 | option before) and drawing now always takes place using CoreGraphics. | |
292 | Likewise, all code using Carbon functions no longer present in OS X | |
293 | 10.4 has been removed to clean-up the code greatly. This is turn | |
294 | means, as mentioned above, that applications will require a minimum | |
295 | of OS X 10.4 in order to run, better yet OS X 10.5.</P> | |
296 | <P ALIGN=JUSTIFY>Apart from these large changes, these additional | |
297 | features can be noted:</P> | |
298 | <UL> | |
299 | <LI><P ALIGN=JUSTIFY>Better support for IconRef</P> | |
300 | <LI><P ALIGN=JUSTIFY>A fix for duplicate menu entries in non-English | |
301 | locales</P> | |
302 | <LI><P ALIGN=JUSTIFY>Accelerators allowed to be used for buttons</P> | |
303 | <LI><P ALIGN=JUSTIFY>wxLocale::GetInfo() implemented using CFLocale</P> | |
304 | </UL> | |
305 | <H3 CLASS="western">wxGTK specific changes</H3> | |
306 | <P ALIGN=JUSTIFY STYLE="margin-bottom: 0cm">The task of the GTK+ port | |
307 | of wxWidgets is to keep up with the development of the GTK+ library | |
308 | since it has the habit of adding new controls or new APIs if the | |
309 | existing code is too limited and cannot be fixed in a backward | |
310 | compatible way. The main problem of this approach is that | |
311 | applications written using wxGTK should work with relatively old | |
312 | versions of GTK+ but should also make use of recent features. In some | |
313 | cases, supporting an old version of GTK+ hinders development so we | |
314 | decided to declare GTK+ 2.4 the minimum toolkit version that is | |
315 | supported. As an example, this made it possible to always use the | |
316 | GTK+ file dialog instead of the old generic file dialog which had to | |
317 | be used when GTK+ didn't have a usable file dialog. | |
318 | </P> | |
319 | <P ALIGN=JUSTIFY STYLE="margin-bottom: 0cm">Other parts of wxGTK that | |
320 | were rewritten or which underwent a major update include, but are not | |

355 | <P STYLE="margin-bottom: 0cm">wxMSW is the most mature platform, | |
356 | mostly because it is used most often and thus has the biggest user, | |
357 | tester and developer base, but also because the underlying Windows | |
358 | system has been more successful at preserving backwards | |
359 | compatibility. Therefore, the list of wxMSW-specific changes is | |
360 | smaller and the changes usually minor details when compared to the | |
361 | changes of the other two main ports:</P> | |
