Re: [pygtk] Pixmap transparency in a GdkDrawable?
On Wed, 4 Oct 2000, Martin Grimme wrote: Hello, again I've got a weird question: When I draw pixmaps onto a GdkDrawable using draw_pixmap(), transparency will be completely ignored. Is there any way around this? I want to draw pixmaps _with_ transparency onto a GdkPixmap. It seems to be possible for GdkPixmaps to have transparent areas. Consider the following piece of code: from gtk import * import _gtk win = GtkWindow() win.show() pix = win.get_window() root = _gtk.gdk_get_root_win() # _root_window() doesn't work... gc = root.new_gc() draw_pixmap(root, gc, pix, 0, 0, 0, 0, 200, 200) This puts the background of the window into the root window. But if there are parts of the window covered or otherwise out of view, those parts are not copied to the root window, thus I assume there is transparency possible for GdkPixmaps (the covered parts seem to be transparent). Pixmaps do not have an alpha channel, so by default, they won't be drawn shaped. When you load a pixmap in pygtk, you may have noticed that you get both a pixmap and the corresponding mask. If you are not using the mask when doing your drawing, then you are doing something wrong :) To use the mask returned when creating the pixmap, you need to assign it to the clip_mask attribute of the GC before drawing. Also, you will need to set clip_x_origin and clip_y_origin attributes if you aren't going to draw the pixmap at (0,0). Now anything you draw with that GC will be clipped to the mask. Please help, if you can! Thank you.

I've defined an accelerator within a GtkText widget (call it 'ctrl-f1'), and bound it to the key. I save it, and in the Glade file, I have: [shevett@cheetah]:~/python/spanker/proj1$ ./spanker.py Gtk-WARNING **: gtk_accel_group_add(): could not find signal "ctrl-f1"in the `GtkText' class ancestry Gtk-WARNING **: gtk_signal_connect_full(): could not find signal "enter" in the `GtkText' class ancestry Okay, fine, that means I need to use a signal that exists. (I think). But what I -rally- want to do is link 'Ctrl-f1' to the 'clicked' signal on a button elsewhere. How do I do this - specifically in python/Glade. :) This is not pygtk problem. You can't just invent signal names like that. Accelerators have to activate an existing signal on an object. If you just want to catch some other key presses on a particular widget, then connect to its key_press_event signal, and handle the key presses there. Thanks!

In the case of the Entry widget, you can connect to focus_out. That will
be sent when the Entry looses to focus and you will get it after, Up, Down
and Tab or when the User clicks somewhere outside the Entry.
But that is not really what I want to achieve.
I want to implement a kind of word completion when somebody press
ALT-SPACE, for example.
So is there any other way than connecting to `KEY_DOWN' and using the
mask and key code ?
It would probably be best to do this with a key_press_event signal
handler. From within the signal handler, check to see if your key has
been pressed, and if so a widget.emit_stop_by_name("key_press_event") to
prevent the normal handling from occuring, do your completion and return
TRUE. Otherwise just return FALSE.
This should be fast enough (how fast do you think people actually type?)

I have encountered a problem using GdkColormap.alloc() on IRIX and Sun systems,

struct _GdkColor

Anyways, here is one patch. I would really appreciate this making it into

return PyGdkColor_New(color);

Yes, that is a known problem and will be fixed in the next release. You

The second requirement is also easy: just don't use set_transient_for(). Does anybody have suggestions for accomplishing both of these tasks at once? Note that the set_transient_for() hint is a window manager hint, and is not interpretted the same by all window managers (some even allow the user to control how it is handled, some ignore it), so it may just be your window manager that prevents the separate iconification.

Excellent! The example of using a CObject as an API container/ accessor made this look very tedious for the implementor; what can I do to make this easier to use? It is not that difficult. I swiped the current setup from the numpy guys :) As for symbols from libraries, I think from python 1.5.2, it doesn't use the RTLD_GLOBAL flag when loading extensions, so the extensions don't pollute the global symbol table. Yes, I understand why, I just recall having lots of problems with the Imlib stuff because of that. That was a year ago, so has probably been fixed at this point, but I must admit that I've not built any of this stuff for a while now. I heard from msw that Red Hat reverted that change in their packages. The problem with imlib (which also occurs in gdk-pixbuf) is that libtool-1.3.x doesn't allow linking one libtool library as a dependency for another. The beta version, libtool-1.3b, allows this but doesn't support as many platforms as 1.3.5. What would be nice would be if ExtensionClass integrated better with python (so that all the special cases for normal classes work for ExtensionClasses). I'd be very interested in your comments on what it would take to make things easier if something like ExtensionClass were available as part of the core, both from the requirements side and ease-of-use perspective. ExtensionClass goes most of the way towards having an easy way to create new class like types from C. I had to patch is a bit to get making subclasses in C, which made it good for most of the rewrite. The real problems lie on the python side. Things like isinstance and issubclass don't work on ExtensionClasses. There are similar problems in other parts of the interpeter where there are special case handling with PyInstance_Check (eg in PyObject_Compare). For these ones, it would be nice if either ExtensionClass was integrated and perform the same sort of special cases when PyExtensionInstance_Check() is true as for normal instances, or if the PyInstance_Check() calls were replaced with ones that would return true for both normal instances and ExtensionClass instances (such as checking for an __class__ attribute). I don't know if you want to integrate ExtensionClass into the python core, so maybe the second option would be better. -Fred James. -- Email: [EMAIL PROTECTED] WWW: http://www.daa.com.au/~james/ ___ pygtk mailing list [EMAIL PROTECTED] http://www.daa.com.au/mailman/listinfo/pygtk
[pygtk] gtk-1.3 bindings
I just got the HEAD branch of gtk+ compiled on my system, so was thinking of starting off binding it. One of the new features is the GObject system, which is what the GtkObject stuff is based on in gtk+-1.3. It provides a non GUI base for objects. I have been wondering about whether to put the base gobject support into a separate module or not, and whether I should keep it separate from the gtk package (when you import gtk, it initialises the GUI). Does this sound like a good idea? I don't know how many non gui libraries will be using gobject, and how many of those will be useful to python programmers. If we want to wrap those libraries and not require gtk be loaded, it will have to be compiled as a separate module.

[pygtk] New snapshot
I have put a new snapshot of pygtk available at: ftp://ftp.daa.com.au/pub/james/python/pygtk-0.7.0-unstable-dont-use.tar.gz This version adds support for GtkGLArea and libglade. These were pretty easy add using the new code generator. In future, it should be very easy to add support for new libraries in pygtk and gnome-python. I also changed things a little bit so arguments that are supposed to accept only GtkObjects that are subclasses of a particular type accept only python objects of that type. This means that you can't add non GtkWidgets to a container for instance. This is important for when I start doing gtk-1.4 support, as almost all types in gtk and gdk are subclasses of GObject. I am at a stage where the extension based pygtk can do most things the old system could. I haven't done any speed tests on it, but it doesn't seem slower (it is probably a bit faster). At this point, it is only worth continuing the gtk-1.2 based work if we are going to release it. The problem with releasing this version is that it causes some breakage, and when gtk-1.4 comes out there will be some more breakage. It may be better to have only one lot of breakage. I am interested if this newest snapshot has any problems that cause portability problems to windows (pygtk-0.6.x has some problems). I think I fixed them so that only makefiles need changing, but I may be wrong.

The names of the files are wrong. pygtk creates libmodule.so.0 which python cannot find. The name must either be module.so or modulemodule.so. 2. AIX cannot link several shared libraries at the same time. Example: the glade and the gtk module use libgtk.so. On AIX, this means that *two independent* libgtk.so are loaded when a python script imports both modules - core dump. There are two solutions: Always link -static on AIX or make sure that only _gtkmodules.so is linked against libgtk.so. 3. When I run PYTHONPATH=. python examples/ide/browser.py, then it core dumps in "import ExtensionClass". In the debugger xldb, I get "Unexpected error: getTextBlock failed (address 0x in pid ...). errno=5: There is an input or output" If anyone could help me to debug this, I could probably provide a patch. My setup: AIX 4.3.2, Compiler ibmcxx 3.6.4.0 With the newer releases, I have been using libtool to link the extensions. If it is behaving wrongly on AIX, it should be reported as a libtool bug.

why are you importing these modules directly? Just use "import gtk" or

the extra brackets are incorrect here.
blue_color = cm.alloc('blue') #segmentation fault
I find it hard to believe that this caused a seg fault. Do you just mean
an exception? I was getting an exception here because of a weird
interaction with ExtensionClass. I have fixed it in CVS now. The fix is
to edit gtk-types.c and insert the following line below the include
statements:
#undef Py_FindMethod
That should fix the problem (after recompiling).
!! how do I get a GtkColor that is, e.g., 'blue'? I would rather use names
than rgb values, but anything would be helpful.
When passing a string argument, you can use any colour name in
/usr/lib/X11/rgb.txt, or hex forms like '#rrggbb' or 'rgb:rr/gg/bb'.

One thing, many constructors in gtk.py, like GtkAdjustment has default values, (at least now) 0.7.0 has not. This is just fine for me since it is closer to the C version. Part of the reason why all functions had default values for the constructors was to get the GtkWhatever(_obj=...) call to work with all objects. This isn't needed now, but having sensible defaults on some objects would probably be a good idea. But will for example GtkCheckButton.active work in 0.7.0 final? Right now I need to use get_active() method. (Ok this is not close to C, but I like it...) I guess that is a bug. It can be fixed by editing gtk.defs and adding the extra field to GtkToggleButton and recompiling. I will add this. There are still a few bugs in the way you can access class attributes in the new pygtk (eg. if a class defines new attributes, you can't get to any of the attributes in a parent class).

[pygtk] ANNOUNCE: pygtk-0.6.6 gnome-python-1.0.53
I have just released pygtk-0.6.6 and gnome-python-1.0.53. It is mainly bug fixes. The gtkhtml module should work correctly now (it uses gnome-config to find the libraries to link with). It also uses the CVS version of automake (automake-1.4a) rather than my old automake patches, and also uses libtool. With this version, it is important that you pass the --prefix=/whatever argument to configure. Before it was ignored when installing the packages, but now it isn't. Either install under the same prefix as python, add a .pth file to your python directory or set PYTHONPATH correctly after installing. If you have trouble building the shared libraries (eg. not getting the correct extension, etc), it is probably a libtool defficiency, and should be followed up with the libtool guys. The tarballs include the latest libtool version (1.3.4), so there shouldn't be too many problems.

[pygtk] ExtensionClass based pygtk
I have done a bit more work on ExtensionClass based pygtk, and have got to a stage where others may want to try it out. I put together a tarball for people who don't have CVS access, or don't want to use it. It is available at: ftp://ftp.daa.com.au/pub/james/python/pygtk-0.7.0-unstable-dont-use.tar.gz (the name is just so people don't complain too much when it breaks their system if they try to install it). To build it, do the following: ./configure --prefix=/usr # or whatever your python prefix is make I don't recommend installing it, as it is not complete and will probably not work on all setups. You can test it out from the build directory though. Pygtk uses libtool now, so to use it without installing it, you will either have to set up some symlinks for the shared libraries, or make your program import ltihooks before importing gtk. Ltihooks is a small set of import hooks that treats .la files as extensions, and resolves the real location of the shared library. The single wrapper stuff is working correctly now, so that can be tested out. Post your comments about the code to the list.

[pygtk] pygtk extensionclass work
I just thought I would post a message saying that the extensionclass based rewrite of pygtk is going pretty well. In fact, you should even be able to test it for very simple things. If you want to do this, here are some instructions: Checkout the extension-class branch of pygtk. This can be done with the following command: cvs -z3 get -f -r extensio-class -d pygtk-ec pygtk (this will check out the extension-class branch of pygtk into the pygtk-ec directory, and if any files don't have the extension-class tag, use HEAD). You will still need my python patches for automake installed on your system (I will switch it over to automake-1.4a soon). Run the following: ./autogen.sh make You can test out the new version from the build directory (I don't recommend installing it at present). As it uses libtool to build the extensions, you will either have to create a few symlinks to get things working, or use a set of import hooks that understand libtool libraries. I have written some hooks like that, so that isn't a problem: import ltihooks ltihooks.install() import gtk Not everything works (in fact there is a lot of unfinished stuff), but you should be able to subclass the available widgets and the single wrapper per GtkObject stuff is working.

Re: [pygtk] pygtk extensionclass work
Well, most of what is in gtk.py is being moved to a C extension module. The types you create in an extension module are not class like, so you can't subclass them for instance. ExtensionClass is a bit of code that allows you to create types that can be subclassed. This way, I can autogenerate the C extension module, and keep the benefits of having the python class wrappers (ie. you could subclass them and set their attributes). We also get all the benefits I mentioned in my message. There is documentation on ExtensionClass on Digital Creation's website (www.digicool.com).

Re: [pygtk] PyGnomeHello and internationalization
There is a gettext module included with gnome-python. It is fairly
similar to the C API, but has some problems with big endian architectures
at the moment (this will be fixed).
You can use it like so:
import gettext
_ = gettext.gettext
gettext.bindtextdomain("translation-domain", "/usr/share/locale")
gettext.textdomain("translation-domain")
print _("Hello world")
If you make the translated strings look like C strings (that is, use
double quotes and no triple quotes, etc), you should be able to use the
standard xgettext program to extract strings.
Alternatively, if you can get your program to translate every string
during its run (difficult if you are trying to translate error messages),
you can set the PY_XGETTEXT environment variable to a file name. Then the
gettext module will work in reverse and output each translated string to
the file named in PY_XGETTEXT. It outputs in standard PO file format,
complete with module name, function name and line number.
You can also use the gettext module for creating or editing message
catalogs:
cat = gettext.Catalog('translation-domain')
cat['Hello world'] = 'hello-world-in-some-other-language'
cat.save('filename.mo')

Re: [pygtk] Re: BOUNCE pygtk@daa.com.au: Non-member submission from [Hans Breuer hans@breuer.org]
There isn't much to see at the moment. I am testing out the modifications on the extension-class-branch tag for the pygtk directory on CVS. You can view the stuff on this branch using bonsai: http://cvs.gnome.org/bonsai/rview.cgi?rev=extension-class-branchdir=gnome-python/pygtkcvsroot=/cvs/gnome Or grab a copy with: cvs -z3 get pygtk -r extension-class-branch Currently, the interesting stuff is in the codegen directory. There is a working C header file parser (h2defs.py) that outputs .defs files using Havoc's new defs file format. There is also a defs file merger (merge.py). It takes a generated defs file, and an older version that contains some hand modifications (ie. information that can't be deduced from the headers, such as default values for arguments) and merges the modifications into the new version. I am about to start work on the code generator, which shouldn't be too difficult -- it should be fairly similar to the old one. When this is finished, it will hopefully be possible to create new extensions from just a defs file (mostly autogenerated) and maybe a few hand coded functions where the code generator couldn't handle. I think I have sorted out the single wrapper per GtkObject problem. By using ExtensionClass, I can do weird things like catching python object destruction, which should help with this sort of thing. This should allow us to have the python wrapper holding a reference to the GtkObject, and if the wrapper is destroyed before the GtkObject, we can `rescue' the wrapper for use if the GtkObject comes back into use within python. This should also allow things like: class MyButton(GtkButton): # extra methods here ...

Re: [pygtk] style question again
There isn't a style.red attribute. To create the colour red in the
colormap used by the widget, use one of the following:
red = widget.get_colormap().alloc('red')
red = widget.get_colormap().alloc('#ff')
red = widget.get_colormap().alloc(0x, 0, 0)
All these forms are equivalent (the last is a little bit faster, but the
first allows the system administrator to redefine red to something else in
/usr/lib/X11/rgb.txt :)

Re: [pygtk] how to adjust scrolledwindow pos
The adjustment for the GtkText widget represents the position in the text.
You can set its value with the set_value() method. Something like:
adj = text.get_vadjustment()
adj.set_value(adj.upper - adj.page_size)
This should adjust where the scrollbar thumb is positioned and the
position in the text.

Re: [pygtk] Inheriting From Widgets
In more complex Tkinter projects, that rule does not seem to be followed. Usually you may want to subclass an existing widget to get some special behaviour. In both pygtk and Tkinter cases, subclassing a widget is the easiest way of achieving this. I don't really have any specific recommendations to do with this. The main one is to not override any of the methods that are straight wrappers for C functions. If the equivalent C function is called on the object, the method of your derived class will not be called, so you can't rely on it.

Using the weak referenced GtkObjects we get to specify a callback to be called on object finalisation. This allows us to prevent the reference loop by making the GtkObject own the python object. The idea is to use this feature to set the pointer to the GtkObject in the python wrapper object to NULL on destruction of the GtkObject, and check for this in methods. This gives us a single wrapper object per GtkObject. Unfortunately, it breaks the following feature: container1.remove(widget) container2.add(widget) Since the python wrapper would not be holding a reference to the GtkWidget here, it would be destroyed between the two method calls. Now if python had weak reference support, we could do this in the other direction. This would mean that the container add/remove example would work, but if all references to the python wrapper disapeared, it would be destroyed. The next time the GtkObject was used from within python, a new wrapper would be created. This is similar to the multiple wrappers per GtkObject senario we have now, where callbacks will usually be passed a different wrapper object than in the function they were created. On the other hand, at any one time there will be at most one wrapper for each GtkObject (ie. wrapper1 and wrapper2 refer to the same object = id(wrapper1) == id(wrapper2)). Would this be good enough for what most people want? This would only be possible if python had support for weak references with finalisation notification like in gtk+.

Re: [pygtk] Still an MDI bug in gnome-python 1.0.51?
I will make a new release soon (and I mean it :). I will just see if I have missed any other bugs that people sent in first. At the moment I am investigating some ideas that will make pygtk easier to maintain, smaller, easier to autogenerate the source of and a few other things. It should also allow having one PyObject - one GtkObject, which people have been wanting for a long time, without circular reference problems. The changes will be using the ExtensionClass code which is currently maintained with zope. This code allows writing new types in C which can be subclassed in python. The idea is to move most of what is in gtk.py into the C part of the package. The code generation phase when building pygtk will probably be using Havoc's new defs file format (which stores more information about how functions relate to different objects, which is very helpful for an object oriented wrapper like pygtk). Havoc is also working on some code to generate these new defs files from C headers, which will make adding python support for other widget libraries trivial -- the steps may be as simple as: 1) generate defs file from C headers 2) possibly make some modifications to generated defs file, or hand code functions that can't be autogenerated. 3) generate source code for python wrapper. 4) compile python wrapper 5) install and use. There are still a few questions I have about ExtensionClass, so I haven't really started work on implementing this yet. I will be making bug fix releases of pygtk/gnome-python when necessary in the mean time.

You probably should read some docs on X's handling of selections before playing around with this (the O'Reilly books probably have something about this). If you only want to do text clipboard transfers, you could use the hack the GnomeIconList widget uses -- create a toplevel GtkWindow (of type popup, so the window manager ignores it) a long way off screen (eg at 2000,2000), and place a GtkEntry in it. You can use the GtkEditable clipboard functions on this widget. You can connect to the GtkEntry's selection_notify_event signal to be notified when a selection changes.

For me when dragging something to the list it returns (0,0) for the label, (1,0) for "First" and None for "Last" The problem appears to be that get_selection_info expects coordinates relative to the top left of the window holding the rows, while the coordinates passed to your dragreceivelist method are relative to the top left of the widget. In your example this causes the row results to be one greater than expected, and the last row to be ignored completely. (Actually, since the title is slightly taller than a normal row you get different results depending on whether you end the drag at the top or bottom of a row.) If you put the GtkCList object inside a scrolled window and add a large number of rows this mismatch is even more pronounced - anything occupying the topmost (row height + cell spacing) pixels will always be reported as row 0, regardless of how far down you scroll. The solution is either to translate the coordinates into the the required format or to obtain the pointer position by some other suitable method once dragreceivelist is called.

This is a pretty close match to the documented behaviour of the function:

Hi,
just playing with drag and drop to CLists and CTrees and there's some
strange thing. I've done something like:
list.connect("drag_data_received", DragReceiveList)
def DragReceiveList(clist, context, x, y, data, info, time):
selection = clist.get_selection_info(x, y)
so this should return row,col of the current selection. The bad
thing is, that it returns (0,x) for the title of the clist,
(1,x) for the first element of the clist and None for the last
element, which is wrong IMHO.
any ideas ?

Re: [pygtk] Can somebody explain the libglade OO paradigm?
What you want is a dictionary of the method objects. The class dictionary
will not do (as that contains unbound methods, where the self parameter
must be explicitely passed.
The instance dictionary also will not do, as it does not contain the
methods either. You would want to use some code something like:
dict = {}
for key in dir(self.__class__):
dict[key] = getattr(self, key)
This will give the bound methods that you can autoconnect with.
I know it is not perfect, but it should do what you want.

Hi I'm making a gnome-hello example for my pygtutorial
http://laguna.fmedic.unam.mx/~daniel/pygtutorial/
and I'm stuck with the libglade example.
I'm trying to do a gnome-hello like the one in my tutorial but with glade.
My problem is the following:
When I autoconect a handler, the handle is called ONLY with the callback
argument and the instance reference isn't passed at all.
PLEASE run the unfinished example I attached to see what I mean.
Select the menu "help" and clik in "about".
The example just instances a GnomeApp with a buton and menus.
My problem comes when I want to show a GnomeAbout I made with glade.
I try to do this selecting "about" in the "help" menu.
Even if I am in the SAME class the "on_about_cb" method can't reference
the self.wtree which I need to show the GnomeAbout widget.
This is because the "on_about_cb" method only recieves the
argument callback but not the instance reference.
--- partial code --
class Application:
def __init__(self):
self.hello = Hello()
self.wtree = libglade.GladeXML('gnome-hello.glade')
print "I instance self.wtree",self.wtree
self.wtree.get_widget('app').connect("destroy", mainquit)
print "***Here is the dictionary ot the instance were I can see\
self.wtree"
print(self.__dict__)
print "Here is the dictionary of the class were I can see\
on_about_cb"
print(Application.__dict__)
self.wtree.signal_autoconnect(Application.__dict__)
def on_about_cb(self,*args):
print "This should contain the instance directory like in\
***",self
print "This should contain the widget",args
#self.wtree.get_widget('about_cb').show()
--
The following code prints when I activate the "about..." menu:
--
I instance self.wtree libglade.GladeXML instance at 81cfb40
***Here is the dictionary ot the instance were I can see self.wtree
{'wtree': libglade.GladeXML instance at 81cfb40, 'hello':
__main__.Hello instance at 8209a50}
Here is the dictionary of the class were I can see on_about_cb
{'__init__': function __init__ at 81f20e0, '__doc__': None,
'on_about_cb': function on_about_cb at 8209a88, '__module__':
'__main__'}
This should contain the instance directory like in *** gtk.GtkBin
instance at 8263f98
This should contain the pixmap ()
---
What I'm I doing wrong?
Note:
I'm not following the SkelImpl.py example because I don't understand his
Object Oriented paradigm. Methods should be with the class they belong to,
not all together in one "GladeHandlers" class.

Re: [pygtk] Width of a widget?
What do you want? The widget's prefered minimum size?

Re: [pygtk] button and application
How did you start the other application? If you are using os.system() then what you are seing is the correct behaviour -- the parent process suspends until the child dies. If you don't want this behaviour, you will need to do the fork/exec yourself. Something like this: pid = os.fork() if pid 0: print "Some error occured during the fork" sys.exit(1) else if pid == 0: # child os.exec(...) # whatever the arguments are supposed to be # anything after this point is only executed if os.exec fails os._exit(1) # not sys.exit() # parent process continues execution here You will also have to do something about reaping the child process when it dies. This is done by setting up a SIGCHLD handler (using the signal module (which has nothing to do with GTK signal handling). If you care about the return value of the child process, the signal handler should be a function that calls os.wait(). If you don't care about the return value, use signal.SIG_IGN as the signal handler. The reason for using os._exit() rather than sys.exit() in the child is that after the fork, the parent and child are sharing file descriptors. If the child exits, then it will tell the X server that it is finished with its connection, breaking the connection for the parent as well. This is avoided by calling os._exit().

Re: [pygtk] pyglade/libglade ignores default-width/default-height ?
I suppose I should put in a message stating that the pyglade module is deprecated. It is probably better to use the libglade module, which uses libglade rather than being pure python. It handles the default_width and default_height attributes correctly.

Re: [pygtk] How do I get the row count from a CList/CTree?
You would use the GtkCTree.node_moveto function. You probably want something like: ctree.node_moveto(node, 0, 0.5, 0.0) The second argument is a column number, the third is the vertical row alignment, and the last is the column alignment (I used 0.0 to put the 0th column at the left of the display).

Re: [pygtk] Pygtk: gtk_gl_area_swapbuffers/swap_buffers
I wrote the gtkglarea wrapper based on what was in cvs back in july. It will compile against the version of gtkglarea in CVS, which has the swapbuffers function marked as deprecated, so I used swap_buffers. The gtkglarea guy has not released a new version since then, which is why the current python gtkglarea wrapper fails. I think there is a snapshot of the newer gtkglarea available on the author's web site which should work.
