<h3>Current version</h3>
|
||
|
|
15th May '98: wxGTK v0.12 (alpha-)
|
||
|
|
<p>
|
||
|
|
This release is hardly more stable than the one before, but it
|
||
|
|
has many new features. It's main purpose is actually to prepare
|
||
|
|
the final merge of the Windows port and the GTK port source
|
||
|
|
trees into a common tree, developed using CVS. The growing
|
||
|
|
number of demos which compile and run with wxGTK "although"
|
||
|
|
being written for wxMSW shows that we seem to be on the right
|
||
|
|
track. One nice new feature for many potential users is that
|
||
|
|
wxGTK no longer needs any extra libraries to be installed,
|
||
|
|
other than the GTK.
|
||
|
|
<p>
|
||
|
|
If you have a compiler
|
||
|
|
better than gcc 2.7.2.2 then you can uncomment a line in src/common/prntbase.cpp
|
||
|
|
which defines __GOOD_COMPILER__. This should make the printing demo work.
|
||
|
|
I haven't got such a compiler, so I actually don't know. Somebody reported
|
||
|
|
problems with version 2.7.2.3 as well.

<h3>What is wxWindows?</h3>
|
||
|
|
wxWindows is a C++ cross-platform GUI toolkit written mainly by Julian Smart.
|
||
|
|
More information about wxWindows can be found at the
|
||
|
|
<a href="http://web.ukonline.co.uk/julian.smart/wxwin">wxWindows Homepage</a>.
|
||
|
|
|
||
|
|
<p>
|
||
|
|
The current version of wxWindows (v1.68) supports Windows ('95 and NT), Motif and
|
||
|
|
XView (aka OpenLook). There is another port (wxXt) available, which uses the
|
||
|
|
free-ware widget set from the Free Widget Foundation (FSF). Ports have been
|
||
|
|
started for the Mac, OS/2 and NextStep.
|
||
|
|
<p>
|
||
|
|
For different reasons, it was decided to start a complete rewrite of wxWindows,
|
||
|
|
which will then be called wxWindows 2.0. For a list of new features and changes
|
||
|
|
from the current version, you may read the wxWindows Homepage (see above).
|
||
|
|
<p>
|
||
|
|
Currently, work is being done on four ports of wxWindows 2.0:
|
||
|
|
<dl>
|
||
|
|
<li> Windows (wxMSW, main author Julian Smart)
|
||
|
|
<li> Unix, Motif (wxMotif, main author Markus Holzhem)
|
||
|
|
<li> Unix, GIMP Toolkit (wxGTK, main author Robert Roebling)
|
||
|
|
<li> Macintosh (wxMac, main author Greg Whitehead)
|
||
|
|
</dl>
|
||
|
|
<p>
|
||
|
|
wxWindows provides a rich set of classes which help to make cross-platform
|
||
|
|
GUI programming easy. In many aspect, it is modelled after MFC, making transition
|
||
|
|
from MFC to wxWindows relatively painless. The main technical
|
||
|
|
difference between most other free or commercial cross platform libraries is
|
||
|
|
that wxWindows is a wrapper around existing widget sets, whereas the other
|
||
|
|
toolkits (Qt, Tk, Java, Amulet, OPaC, JX, Fresko) draw their widgets themselves,
|
||
|
|
which results in applications having a different look than native applications
|
||
|
|
for that specific platform.
|
||
|
|
<p>
|
||
|
|
There are classes for the following categories
|
||
|
|
<dl>
|
||
|
|
<li> Window classes: wxWindow, wxFrame, wxDialogBox, wxPanel, wxCanvas etc.
|
||
|
|
<li> Widget classes: wxButton, wxCheckbox, wxChoice, wxListBox, wxListCtrl, wxText, wxGauge etc.
|
||
|
|
<li> Data structures: wxList, wxString, wxHashTable, wxDate etc.
|
||
|
|
<li> Layout/constraint system
|
||
|
|
<li> GDI classes: wxPen, wxBrush, wxFont, wxBitmap etc.
|
||
|
|
<li> Events: wxCommandEvent, wxMouseEvent, wxKeyEvent etc.
|
||
|
|
<li> Devices contexts: wxCanvasDC, wxPostScriptDC, wxMemoryDC, wxPrinterDC
|
||
|
|
<li> Base classes for runtime-type information: wxObject
|
||
|
|
<li> Interprocess communication: wxClient, wxConnection, wxSocket, wxServer etc.
|
||
|
|
<li> Document-view architecture: wxDocument, wxView, wxDocManager etc.
|
||
|
|
<li> Printing framework: wxPreviewFrame, wxPrintDialog, wxPrinter etc.
|
||
|
|
<li> Many helper classes, wxApplication, wxTypeTree, wxPathList etc.
|
||
|
|
<li> Classes for internationalization
|
||
|
|
<li> Built-in memory leak checking, log-files
|
||
|
|
<li> A multitude of functions and macros

<h3>Copyright</h3>
|
||
|
|
The choice of a suitable copyright has been subject to endless discussions. It
|
||
|
|
has always been the aim, to put wxWindows under a copyright, which protects
|
||
|
|
the work of its authors while at the same time encouraging the use of wxWindows
|
||
|
|
in as many projects as possible.
|
||
|
|
<p>
|
||
|
|
The (so far) last decision has been to put the whole of wxWindows
|
||
|
|
under a modified (less restrictive) version of the GNU library general
|
||
|
|
public license.
|
||
|
|
<p>
|
||
|
|
The only exception is that wxGTK now contains code (gdk_imlib) which is
|
||
|
|
under the GNU library general public license. When you make changes to
|
||
|
|
this part of wxGTK, you'll have to make these changes public (in contrast
|
||
|
|
to changes to the rest).
|
||
|
|
<p>
|
||
|
|
It is obviously encouraged that anybody who uses wxWindows and who
|
||
|
|
makes any improvements to it will make these changes available to
|
||
|
|
wxWindows' authors.

<h3>What can I do with wxWindows 2.0?</h3>
|
||
|
|
wxWindows is still in alpha stage, which means that there are still bugs
|
||
|
|
waiting for you and several features are not yet (fully) implemented, but
|
||
|
|
you can expect the interface to be more or less stable, so no major
|
||
|
|
modifications will have to be made to your source code. wxGTK is already
|
||
|
|
used in a number of medium sized projects and is it being developped
|
||
|
|
in close cooperation with the authors of these applications.

||

<h3>Can I write a GNOME application with wxGTK 2.0?</h3>
|
||
|
|
Good question. The idea to use wxGTK for the GNOME desktop environment is
|
||
|
|
quite obvious. When this topic came up on the GNOME mailing list, the GNOME
|
||
|
|
people have shown an amazingly negative opinion about wxWindows. One reason
|
||
|
|
might be that several of the main authors of the GNOME-project consider
|
||
|
|
C++ a "broken language". I don't share that view and I am sure many people
|
||
|
|
find C++ easier to handle and better suited for GUI programming than C.
|
||
|
|
<p>
|
||
|
|
Just recently, the topic of C++ in general and wxGTK in particular appeared
|
||
|
|
again on the GNOME list. It has shown that - at least - the opinion on C++
|
||
|
|
on the GNOME list is split.
|
||
|
|
<p>
|
||
|
|
There is already a C++ wrapper for the GTK called GTK-- written by Tero Pulkkinen.
|
||
|
|
It is very small and adds very little overhead to the GTK. If platform
|
||
|
|
independence is no issue for you and you want to write a small tool
|
||
|
|
for Linux, you should probably use GTK--. Of course you can use wxGTK
|
||
|
|
for that, too :-)

||

<h3>Screenshots</h3>
|
||
|
|
What would a home page of a GUI be without a screenshot? Well, as wxWindows
|
||
|
|
is a wrapper around existing widget/item sets, a wxWindows application will
|
||
|
|
look like any other native Windows, Motif, GTK or Mac application.
|
||
|
|
<p>
|
||
|
|
But for those of you, who wouldn't download wxGTK only because there
|
||
|
|
is no screenshot,
|
||
|
|
<a href="ftp://ftp.freiburg.linux.de/pub/linux/wxxt/sshot.jpg">here it comes</a>.

<h3>News from wxGTK 0.12</h3>
|
||
|
|
<p>
|
||
|
|
PNG, zlib and gdk_imlib code included.
|
||
|
|
<p>
|
||
|
|
MDI implementation. More a basis for further testing
|
||
|
|
than of real value.
|
||
|
|
<p>
|
||
|
|
Split "--with-debug" option into two options: "--with-debug_info"
|
||
|
|
and "--with-debug_flag". The first one sets the "-g" flag when
|
||
|
|
compiling, the second defines "DEBUG" in setup.h (which is included
|
||
|
|
from defs.h).
|
||
|
|
<p>
|
||
|
|
Merged DocView framework. The sample doesn't compile yet, because
|
||
|
|
it uses features from wxTextCtrl, which I haven't implemented yet.
|
||
|
|
<p>
|
||
|
|
Merged TabCtrl. Doesn't look perfect, but it seems to work.
|
||
|
|
<p>
|
||
|
|
Merged remaining classes from the newest wxMSW alpha. (wxDynArray,
|
||
|
|
wxModule etc.).
|

<h3>Installation of wxGTK under Linux</h3>
|
||
|
|
|
||
|
|
GTK requires an up-to-date version of the
|
||
|
|
<dl>
|
||
|
|
<li> GTK (GIMP ToolKit)
|
||
|
|
</dl>
|
||
|
|
to be installed as a shared lib on your system. wxGTK is being developped with
|
||
|
|
version 1.0.1 and it is known not to work with earlier versions.
|
||
|
|
The GTK library is available from
|
||
|
|
<a href="ftp://ftp.gtk.org/pub/">somewhere here (gtk.org).</a>
|
||
|
|
After having typed "make install" the GTK header files should be
|
||
|
|
in "/usr/local/include". Correct me, if I am wrong.
|
||
|
|
<p>
|
||
|
|
Compilation itself works as usual with autoconf:
|
||
|
|
<dl>
|
||
|
|
<li> Unpack it to a suitable subdirectory, let's say ~/wxGTK
|
||
|
|
<li> Type "cd wxGTK"
|
||
|
|
<li> Type "configure"
|
||
|
|
<li> Type "make"
|
||
|
|
</dl>
|
||
|
|
Some demos use files stored in the source directory of those demos
|
||
|
|
(e.g. internat uses files in samples/internat) whereas the binaries
|
||
|
|
will end up in samples/internat/linux. You'll have to copy the binaries
|
||
|
|
down or call them like "linux/test" from samples/internat. This is
|
||
|
|
also the case for wxTest (which should display a horse).
|
||
|
|
<p>
|
||
|
|
You can create a shared library by adding the option "--with-shared" to
|
||
|
|
the "configure" command. Afterwards, you'll have to copy the library
|
||
|
|
~/wxGTK/lib/linux (if you have Linux) to a directory in your LDPATH (e.g. /usr/X11R6/lib)
|
||
|
|
and run "ldconfig".

<h3>Mailing list for wxGTK</h3>
|
||
|
|
The mailing list (as well as this page) is called wxxt for more
|
||
|
|
or less historical reasons.
|
||
|
|
<p>
|
||
|
|
You can subsribe to the mailing list by sending a mail to
|
||
|
|
<a href="mailto:majordomo@wesley.informatik.uni-freiburg.de">majordomo@wesley.informatik.uni-freiburg.de</a>.
|
||
|
|
This mail must contain the text "subscribe wxxt" in the body (not the subject) of the
|
||
|
|
mail. You will then get a confirmation that somebody asked majordomo to put you
|
||
|
|
on the list and you will have to confirm this once again by sending back
|
||
|
|
the authentisation, which comes in the confirmation mail. The last step
|
||
|
|
is also described in the actual confirmation mail (I think).
|
||
|
|
<p>
|
||
|
|
You can send a mail to the mailing list to the address
|
||
|
|
<a href="mailto:wxxt@www.freiburg.linux.de">wxxt@www.freiburg.linux.de</a>.
|
||
|
|
|
||
|

Unsubscribe by sending "unsubscribe wxxt" to majordomo (see above). Not to
