<H3 CLASS="western">What is wxWidgets?</H3>
|
|
|
|
|
<P ALIGN=JUSTIFY>Although it is quite unlikely that you'll read this
|
|
|
|
|
document if you don't know what wxWidgets is, let's just briefly
|
|
|
|
|
mention that wxWidgets is a C++ framework for building rich GUI
|
|
|
|
|
applications from a single source which can then be compiled on
|
|
|
|
|
different operating systems, resulting in a native application on
|
|
|
|
|
each system. wxWidgets uses native controls (or widgets) and other
|
|
|
|
|
native functions whereever possible so that the resulting
|
|
|
|
|
applications will look and feel as native as possible, and they are
|
|
|
|
|
usually not distinguishable from applications written using single
|
|
|
|
|
platform toolkits such as MFC for Windows, GTK+ for Linux or Cocoa
|
|
|
|
|
under OS X. In some areas (such as graphics art or the installer),
|
|
|
|
|
adaptations to the individual platforms have to be made in order to
|
|
|
|
|
achieve perfect integration with that platform.</P>
|
|
|
|
|
<P ALIGN=JUSTIFY>The major operating system for which wxWidgets
|
|
|
|
|
supports are Windows (Windows 95, NT, 2000, XP, Vista) including its
|
|
|
|
|
mobile variants (Windows CE, PocketPC, Windows Mobile), Linux and
|
|
|
|
|
Unix using the GTK+ 2 toolkit (minimum version is GTK+ 2.4, more
|
|
|
|
|
recent features are used when available) and Mac OS X (minimum
|
|
|
|
|
version 10.4 Tiger, both Intel, PPC and the Universal Binaries for
|
|
|
|
|
both are supported). wxWidgets includes many code pieces for
|
|
|
|
|
optimising dialog and general layout for small screens such as those
|
|
|
|
|
of the recent netbooks and mobile phones and tablets.</P>
|
|
|
|
|
<P ALIGN=JUSTIFY>There is varying support for other platforms or
|
|
|
|
|
toolkits such as OS/2, Motif, GTK 1.2, PalmOS and various mobile
|
|
|
|
|
Linux variants using GTK+ or the Hildon framework and also a version
|
|
|
|
|
for OS X using the Cocoa API and even the iPhone SDK.</P>

|
|
|
|
<H3 CLASS="western">Documentation in Doxygen</H3>
|
|
|
|
|
<P ALIGN=JUSTIFY STYLE="margin-bottom: 0cm">Until wxWidgets 3.0 all
|
|
|
|
|
documentation was written in a customized LaTeX variant created for
|
|
|
|
|
the project years ago. Although there were tools which could parse
|
|
|
|
|
classes automatically and create a documentation skeleton, class
|
|
|
|
|
documentation was troublesome to update and therefore often outdated.
|
|
|
|
|
In order to improve this situation, the entire documentation
|
|
|
|
|
including references and overviews was converted to a customized
|
|
|
|
|
Doxygen format inlined in a special set of headers. Although many
|
|
|
|
|
classes were converted in a single automated step, every class
|
|
|
|
|
documentation had to be corrected by hand making this effort one of
|
|
|
|
|
the biggest in the development cycle leading up wxWidgets 3.0.
|
|
|
|
|
Additionally, tools were written to automatically compare the
|
|
|
|
|
signature of the many class methods to the documentation. The result
|
|
|
|
|
is more correct documentation with better formating and built-in
|
|
|
|
|
searching and screenshots of many controls. Since Doxygen is a
|
|
|
|
|
wide-spread format and easy to learn, the new documentation is much
|
|
|
|
|
easier to edit, correct and read. See the <A HREF="http://docs.wxwidgets.org/trunk/index.html">wxWidgets
|
|
|
|
|
on-line documentation</A> to which this document refers to in many
|
|
|
|
|
places.</P>

<H3 CLASS="western">C++ features and template support</H3>
|
|
|
|
|
<P ALIGN=JUSTIFY STYLE="margin-bottom: 0cm">The wxWidgets project
|
|
|
|
|
tries to both move with new developments of the C++ language as well
|
|
|
|
|
as to support older compilers to an extent which does not inhibit
|
|
|
|
|
further development and indeed the usefulness of the entire project.
|
|
|
|
|
Since support for templates used to be limited to a few compilers and
|
|
|
|
|
was often buggy even in them, wxWidgets initially stayed away from
|
|
|
|
|
using templates entirely including the use of the Standard Template
|
|
|
|
|
Library (STL). In the meantime nearly all compilers have gained solid
|
|
|
|
|
template support and therefore wxWidgets is now using templates for
|
|
|
|
|
container classes (such as <A HREF="http://docs.wxwidgets.org/trunk/classwx_vector_3_01_t_01_4.html">wxVector<T></A>),
|
|
|
|
|
smart pointers (such as <A HREF="http://docs.wxwidgets.org/trunk/classwx_shared_ptr_3_01_t_01_4.html">wxSharedPtr<T></A>),
|
|
|
|
|
weak references (see <A HREF="http://docs.wxwidgets.org/trunk/classwx_weak_ref_3_01_t_01_4.html">wxWeakRef<T></A>)
|
|
|
|
|
and many other places where templates are useful. This means that
|
|
|
|
|
very old compilers won't be able to compile wxWidgets anymore or only
|
|
|
|
|
in a degraded way (such as Visual C++ 6.0).</P>
|
|
|
|
|
<H3 CLASS="western">Platform features and backwards compatibility</H3>
|
|
|
|
|
<P ALIGN=JUSTIFY STYLE="margin-bottom: 0cm">In the same way wxWidgets
|
|
|
|
|
tries to both make use of new features of the different operating
|
|
|
|
|
systems and support older systems for as long as possible and as long
|
|
|
|
|
as supporting them does not hinder development for up-to-date
|
|
|
|
|
systems. This is especially true for OS X and GTK+ 2 and it was
|
|
|
|
|
therefore decided that OS X versions older than 10.4 Tiger and GTK+ 2
|
|
|
|
|
version older than 2.4 are no longer supported. The wxWidgets team
|
|
|
|
|
also realized that it could not do everything and that support for a
|
|
|
|
|
cross-platform database API was beyond the scope and focus of the
|
|
|
|
|
project so that its old wxODBC database connectivity classes were
|
|
|
|
|
removed from the project. There are many cross-platform database
|
|
|
|
|
libraries available and many of them are better than the old wxODBC
|
|
|
|
|
and all of them are better maintained.</P>

<H3 CLASS="western">Unicode: A Single Build for Everyone</H3>
|
|
|
|
|
<P ALIGN=JUSTIFY STYLE="margin-bottom: 0cm">Until version 3.0 there
|
|
|
|
|
have always been two different versions (or builds) of wxWidgets: one
|
|
|
|
|
with full support for Unicode where each character was represented by
|
|
|
|
|
a wchar_t internally (using two bytes under Windows and four bytes
|
|
|
|
|
almost everywhere else) and another called the „ANSI“ build where
|
|
|
|
|
each character was represented by a single byte. This model was
|
|
|
|
|
chosen following the original Windows API model and at a point of
|
|
|
|
|
time when Unicode support was hardly present anywhere else. In the
|
|
|
|
|
meantime, the Windows world together with projects such as Java have
|
|
|
|
|
chosen UTF-16 as the native representation for Unicode strings
|
|
|
|
|
whereas much of the free software world including GTK+ and parts of
|
|
|
|
|
Mac OS X have chosen UTF-8. It was therefore decided to drastically
|
|
|
|
|
change the implementation of wxWidgets' string class and make it use
|
|
|
|
|
UTF-16 under Windows (mostly as before) but UTF-8 elsewhere (instead
|
|
|
|
|
of wide character strings using wchar_t) so that strings received
|
|
|
|
|
from and sent to Unix and GTK+ library calls would no longer have to
|
|
|
|
|
be converted back and forth between different Unicode representations
|
|
|
|
|
(see <A HREF="http://docs.wxwidgets.org/trunk/classwx_string.html">wxString</A>
|
|
|
|
|
and <A HREF="http://docs.wxwidgets.org/trunk/overview_unicode.html">Unicode
|
|
|
|
|
overview</A>). Additionally, the „ANSI“ mode was removed and the
|
|
|
|
|
wxString class as well as some other classes were modified to accept
|
|
|
|
|
and return both Unicode and 8-bit string literals if required. The
|
|
|
|
|
same was done to functions like wxPrintf() etc. Although this change
|
|
|
|
|
will eventually not be seen by the end user of an application written
|
|
|
|
|
using wxWidgets, it is such a fundamental change that it was the
|
|
|
|
|
primary reason to give wxWidgets the new major version number 3.</P>

<H3 CLASS="western">New 2D Drawing Code</H3>
|
|
|
|
|
<P ALIGN=JUSTIFY STYLE="margin-bottom: 0cm">Although a 2D drawing API
|
|
|
|
|
has always been part of wxWidgets (using so-called device contexts
|
|
|
|
|
such as a window or a bitmap and pens and brushes to draw into them,
|
|
|
|
|
see <A HREF="http://docs.wxwidgets.org/trunk/classwx_d_c.html">wxDC</A>,
|
|
|
|
|
<A HREF="http://docs.wxwidgets.org/trunk/classwx_pen.html">wxPen</A>,
|
|
|
|
|
<A HREF="http://docs.wxwidgets.org/trunk/classwx_brush.html">wxBrush</A>),
|
|
|
|
|
it has not changed much since its initial inception and so the code
|
|
|
|
|
was completely reorganized using a single set of frontend classes and
|
|
|
|
|
different backends which will make maintainance much easier without
|
|
|
|
|
having to care for binary backwards compatibility and it also helped
|
|
|
|
|
isolate a number of subtle platform differences. The old drawing API
|
|
|
|
|
is good enough for many tasks and reflects the drawing capabilites of
|
|
|
|
|
the 1990's but it didn't make use of advanced features such as
|
|
|
|
|
transparency, anti-aliasing and free matrix transforms of modern 2D
|
|
|
|
|
graphics systems such as GDI+ on Windows, Cairo on Linux (and
|
|
|
|
|
elsewhere) and CoreGraphics on OS X. Therefore a completely new
|
|
|
|
|
drawing API (the so called graphics contexts, see <A HREF="http://docs.wxwidgets.org/trunk/classwx_graphics_context.html">wxGraphicsContext</A>)
|
|
|
|
|
was added to wxWidgets making use of modern drawing engines. This is
|
|
|
|
|
complemented by a bitmap class with alpha channel support and fast
|
|
|
|
|
raw access to the bitmap's internal data representation. Additionally
|
|
|
|
|
the API of all existing GDI class constants was corrected so that
|
|
|
|
|
wxMODERN becomes wxFONTFAMILY_MODERN, wxSOLID becomes
|
|
|
|
|
wxBRUSHSTYLE_SOLID etc. and the reference counting system was
|
|
|
|
|
streamlined and made identical on all platforms.</P>

<H3 CLASS="western">Changes to wxBase</H3>
|
|
|
|
|
<P ALIGN=JUSTIFY>wxBase is the name of the non-GUI part of wxWidgets
|
|
|
|
|
libary which provides basic class such as the aforementioned wxString
|
|
|
|
|
class, container classes, as well as classes for threading,
|
|
|
|
|
networking, XML parsing, path and configuration management, logging,
|
|
|
|
|
debugging etc. These functions and classes have been separated into
|
|
|
|
|
their own library both for being able to write non-GUI apps as well
|
|
|
|
|
as to make maintainance easier through reduced interdependence.
|
|
|
|
|
</P>
|
|
|
|
|
<P ALIGN=JUSTIFY>Many of the changes to wxString and the container
|
|
|
|
|
classes are located in wxBase, but on top of that support to wxBase
|
|
|
|
|
was added for events loops, timers and sockets for writing
|
|
|
|
|
event-based client or server apps with wxWidgets 3.0. The socket code
|
|
|
|
|
itself has been reorganized removing a lot of duplicated code and
|
|
|
|
|
dropping the previous implementation which was separated into a C and
|
|
|
|
|
a C++ part.</P>

change. Rather, this paragraph summarizes the most relevant changes

to the GUI classes of wxWidgets. Given wxWidgets' nature as a GUI

<LI><P ALIGN=JUSTIFY>wxDataViewCtrl and wxDataViewTreeCtrl: this
|
|
|
|
|
control can partially replace both wxListCtrl and wxTreeCtrl (for
|
|
|
|
|
which there only was a native version of Windows and partially for
|
|
|
|
|
OS X) but also extends and combines the classes by being able to
|
|
|
|
|
display a hierarchy and list at the same time and by offering a much
|
|
|
|
|
more flexible way to display and edit data on a per column basis.
|
|
|
|
|
Reimplementing wxTreeCtrl and possibly wxListCtrl in terms of
|
|
|
|
|
wxDataViewCtrl was considered, but this was dropped as certain
|
|
|
|
|
special features are not available on all platforms (or
|
|
|
|
|
differently). See also <A HREF="http://docs.wxwidgets.org/trunk/classwx_data_view_ctrl.html">wxDataViewCtrl</A>

<LI><P ALIGN=JUSTIFY>The tabular view of wxGrid has been improved
|
|
|
|
|
including a native header control, which has been separated into a

|
|
|
|
new control. See also <A HREF="http://docs.wxwidgets.org/trunk/classwx_grid.html">wxGrid</A>

control used to display lists and hierarchies of name-value pairs.
|
|
|
|
|
Like wxDataViewCtrl, it offers a number of ready-to-use editors for

editing text, numbers, lists, fonts, file names etc. using in-place

editing or using pop-up dialog and combo boxes. Developement of

<LI><P ALIGN=JUSTIFY>wxHyperlinkCtrl added, implemented natively
|
|
|
|
|
under GTK+ and in a generic way on other platforms. It can be used

<H3 CLASS="western">wxMac specific changes (now called wxOSX)</H3>
|
|
|
|
|
<P ALIGN=JUSTIFY>One important change of the wxMac port is that the
|
|
|
|
|
port is not called wxMac anymore. Instead, the more appropriate term
|
|
|
|
|
wxOSX should be used as the operating system is called OS X nowadays
|
|
|
|
|
and – more importantly – wxWidgets now has partial support for
|
|
|
|
|
iPhone and iPod, and these are devices are clearly not Macs. Apart
|
|
|
|
|
from the name change – wxMac has undergone the most fundamental
|
|
|
|
|
changes of the three main ports, even if some of the changes were
|
|
|
|
|
mostly reorganizing code instead of writing new code. The code has
|
|
|
|
|
been reorganized into common code (common to Carbon, Cocoa and Cocoa
|
|
|
|
|
Touch) including both general wrapping or front-end classes for much
|
|
|
|
|
of the GUI code as well as a wrapper for the so called CoreFoundation
|
|
|
|
|
classes of OS X, which are responsible on all OS X variants for
|
|
|
|
|
string manipulation, font support, graphics and other basic
|
|
|
|
|
functionality (CoreImage and CoreVideo have recently been added by
|
|
|
|
|
Apple) and toolkit dependent code for the Carbon, Cocoa and Cocoa
|
|
|
|
|
Touch API. The Carbon variant is the core of what used to be wxMac
|
|
|
|
|
and is the most stable and mature version. The reason behind adding
|
|
|
|
|
optional support for Cocoa and Cocoa Touch is that Carbon is not
|
|
|
|
|
available on iPhones at all and that it has been deprecated for all
|
|
|
|
|
64-bit versions of OS X, which is likely to be the default a few
|
|
|
|
|
years from now. So while present applications using wxOSX are advised
|
|
|
|
|
to use the Carbon backend due its maturity, future developement will
|
|
|
|
|
have to focus on the Cocoa backend.</P>
|
|
|
|
|
<P ALIGN=JUSTIFY>As part of the restructuring, all remaining drawing
|
|
|
|
|
code using the old QuickDraw API has been removed (it was only an
|
|
|
|
|
option before) and drawing now always takes place using CoreGraphics.
|
|
|
|
|
Likewise, all code using Carbon functions no longer present in OS X
|
|
|
|
|
10.4 has been removed to clean-up the code greatly. This is turn
|
|
|
|
|
means, as mentioned above, that applications will require a minimum
|
|
|
|
|
of OS X 10.4 in order to run, better yet OS X 10.5.</P>
|
|
|
|
|
<P ALIGN=JUSTIFY>Apart from these large changes, these additional
|
|
|
|
|
features can be noted:</P>
|
|
|
|
|
<UL>
|
|
|
|
|
<LI><P ALIGN=JUSTIFY>Better support for IconRef</P>
|

<H3 CLASS="western">wxGTK specific changes</H3>
|
|
|
|
|
<P ALIGN=JUSTIFY STYLE="margin-bottom: 0cm">The task of the GTK+ port
|
|
|
|
|
of wxWidgets is to keep up with the development of the GTK+ library
|
|
|
|
|
since it has the habit of adding new controls or new APIs if the
|
|
|
|
|
existing code is too limited and cannot be fixed in a backward
|
|
|
|
|
compatible way. The main problem of this approach is that
|
|
|
|
|
applications written using wxGTK shoud work with relatively old
|
|
|
|
|
versions of GTK+ but should also make use of recent features. In some
|
|
|
|
|
cases, supporting an old version of GTK+ hinders development so we
|
|
|
|
|
decided to declare GTK+ 2.4 the minimum toolkit version that is
|
|
|
|
|
supported. As an example, this made it possible to always use the
|
|
|
|
|
GTK+ file dialog instead of the old generic file dialog which had to
|
|
|
|
|
be used when GTK+ didn't have a usable file dialog.
