[pygtk] understanding documentation
I hope I'm not nitpicking too much but I'm having some difficulty understanding the documentation at: http://www.gnome.org/~james/pygtk-docs/class-gtktreeview.html Since pygtk is being discussed ... should C functions be referenced? For example, under the gtk.TreeView.set_cursor section: "... followed by gtk_widget_grab_focus (tree_view) in order ..." might make more sense if shown as: "... followed by tree_view.grab_focus() in order ..."

[pygtk] gtk.Text()
I'm trying to use the GtkText widget without any luck. text = gtk.Text() This return "AttributeError: 'module' object has no attribute 'Text'". Is there a different name for this widget?

There are unfortunately not lots of documentation.
But if you have experience with the old bindings, you can look at the
code in either way gtk.c (auto-generated) eller gtk.override

PyGObject_Type for GObject based object, or even better
PyGtkWidget_Type (PyGtkContainer_Type etc)

Do you have a traceback?
Do you have the code somewhere, so I can help you debug what's wrong?

[pygtk] Another threading/progressbar Question
Hi,
i'm new to this list and a newbie in programming with pygtk so please
forgive this stupid question.
I'm trying to write an python app which copies a file over a network.
While the coping will take place in a separate thread, i want to observe
the progress with a progressbar using a timeout. So for testing the
usage of progressbars i wrote the little piece of code below (observing
a counter).
The timeout function does it's job very well but there is a problem in
my thread.
The programm hangs without an error message when i remove the timeout. I
must have misunderstood something (gtk.threads_{enter/leave} or so).
Could you please give me hint?
I found some discussion of threading problems with pygtk in the list
archive and also some hints, but i am trying to solve this issue for
days without success. My system is Red Hat 8.0. I also updated to the
newest packages i found (rawhide) and recompiled the pygtk2.src.rpm
("./configure --enable-thread" was neccessary).
gtk+-1.2.10-23
gtk2-2.1.5-1
gtk2-devel-2.1.5-1
gtk2-engines-1.9.0-6
gtk+-devel-1.2.10-23

Any help would be appreciated.

With the new tree widget, the selection is abstracted as a separate object, which can be obtained with: selection = treeview.get_selection() (I think the original reason for this was to allow two views of one model to share a selection). For single selection tree views, you can call selection.get_selected() to retrieve the selected row. For notification of changes to the selection, connect to the selection's "changed" signal.

[pygtk] Porting of wrapper from pygtk1 to pygtk2
Hi all,
I am currently trying to port the python wrapper for a gtk widget
(gtkscintilla2).
*** SOME CONTEXT:
Original wrapper works with pygtk1 (say 'W1').
Since the gtk widget is now available for gtk2, I am trying to modify
W1 in order to make it working with pygtk2 (say 'W2').
I have to say I am not sure about the result, since I am not as much
familiar with pygtk c-side as I'd like, and in general with gtk. In
particular in W1 I found many references to functions PyGtk_{New, Get,
Type}, defined by pygtk.h.
In W2 pygtk.h does no longer export like that functions. Instead,
pygobject.h exports similar functions, and I tried to guess the
matching as follows (don't know if this is correct):
#define PyGtk_New pygobject_new
#define PyGtk_Get pygobject_get
#define PyGtk_Type PyGPointer_Type
*** THE PROBLEM:
W2 initialization code simply calls init_pygtk().
After initialization, every time W2's code calls PyGtk_New
(=pygobject_new) a segfault occurs.
Don't know if I provided information enough, but can someone
understand what am I missing?
More in general, there exist documents or tutorials that explain how
to build pygtk wrappers for gtk widgets?
Thank you,
roberto

I have had to use the "cursor_changed" signal which emits two signal on the first click because no row was initially selected. What TreeView signal can I use to replace "select_row"?
