This may just be a minor inconvenice. Why don't you try the attached module? That way you can just use a Win32 event. import gsource import win32event queue_event = win32event.CreateEvent(None, 0, 0, None) qeid = gsource.add(queue_event, gsource.IO_IN, callback, arg) When you want to run the queue callback just do a win32event.SetEvent(queue_event). That's all there is to it! The setup.py file was something I just hacked up for this email. I think it should work.

[pygtk] Windows Threading Fixes
So in order to address the threading bugs in Win32 once and for all, I submit this little code snippet which is a very Proof of Concept thing I wanted to use just to see if the concept worked and wasn't too aweful. I haven't tried the idle() solution yet. I might check to see if it's better tomarrow (without sucking 100% cpu), but for now, this seems to work. Once I get my whole program ported over to it, I'll put my finished version in the FAQ. -dave testgui.tgz Description: Binary data ___ pygtk mailing list [EMAIL PROTECTED] http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://www.async.com.br/faq/pygtk/
[pygtk] Memory leak caused by set_cell_data_func and subsequent call of rendering function?
Hi,
I am seeing a significant memory leak when using the
set_cell_data_func() method of a gtk.TreeViewColumn. I have included an
example program that illustrates the problem, I am using python2.3 on
Sun Solaris 5.9 but also see the problem when running on a Linux box.
Each time the rendering function (renderFunc) is called the memory usage
increases, even when the rendering function executes no code. When I
commend out the call to set_cell_data_func() the memory leak does not
occur.
Any help would be greatly appreciated.
Thanks,
Liza

Yes, bonobo automatically finds a component that can open the MIME
type of the URI. However, that may not be very helpful in practice,
since it may find the worst of several components capable of displaying
that MIME type.
Can you try the test program in attachment? It should print an object
reference. For me it prints:
[emperor:tmp]$ ./test-bonobo-monikers.py

Apparently others want multi-line text in trees, too, so here is my version: (first release, not really polished, but should work. It should be good enough for debugging, but not for end-user release.) http://abeld.web.elte.hu/wrappedtext.tar.gz It is a C widget, you need to compile the widget part first. It can also be edited, the editing is handled by a TextView which is modified to implement the CellEditable interface. I will use it in an outliner program I am working on. I also tried the 'draw a pango layout on the widget' idea, but I decided against it. Can't exactly remember why, I think I had problems with setting the cell size. You set it to be big enough, right? So there will be a varying amount of space below each cell.

some times ago i composed an example for what you want. i had the
intention to let it "rest" for a while, then going throug again, but
did't do it yet.
the tooltips with the example are actually popup-windows. it has at
least the advantage that one can put into all kind of stuff.
the tips are created for cells but it would likely not difficult to do
the same trick only for rows.
although this version is ugly and raw it could be helpful for you or
others. maybe someone can provide improvements too.
