I started to add this one, but I'm not entirely sure what you mean. From the code, it *looks* like you're expanding all the rows up to a certain point (the target of the path), and then expanding the target's children. Am I right?

[pygtk] Temporarily disabling a TreeView from sorting?
I have a TreeView that can contain hundreds to thousands of entries. It can take 60 seconds or more to enter data into the tree. However, if sorting was never enabled, it takes under 2 seconds. Is there a way of temporarily disabling sorting while data is being entered, and the reenabling sorting after the data has been entered? -- Don Allingham <[EMAIL PROTECTED]> GRAMPS OpenSource Genealogy signature.asc Description: This is a digitally signed message part ___ pygtk mailing list [EMAIL PROTECTED] http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://www.async.com.br/faq/pygtk/

JamesH will be able to answer this a bit more completely, but the format is described in codegen/README.defs (in the source tarball). I don't think that the current codegen implementation actually uses all of the features described in that file. There was at one point a concerted effort to sort out language bindings (which was how README.defs came about in the first place). The rest of the history is something I do not know.

Mmh.. I answered that, because, i think that you were talking about a
"runtime" reference :-). Maybe because, I saw, in one of the faqs, that for
using the module created, one should import pygtk before importing the
module created.
Talking about packages, I also think that it's not crazy to release
python-gtk's-gen separated! :-)

Ok, and, as Charles said, it's on python-gtk2-dev has pygtk-codegen!
Thanks for the answers!

My bad.. this actually happens because I forgot to tell installer
about the "atk" module (and because pygtk will silently continue
running after an import failure.. *sigh*).
Anyway.. now I got back to the original problem I was trying to solve.
I am also using pygtkgl, it fails when trying to do an import:
if ((module = PyImport_ImportModule("gtk.gdkgl")) != NULL) {
[...]
} else {
PyErr_SetString(PyExc_ImportError,
"could not import gtk.gdkgl");
return;
gtk.gdkgl is failing to load, even though I did ensure to copy
_gdkgl.so to the install directory. Has anyone experience this before
or found out the issue?
Still investigating...

[pygtk] McMillan Installer problems
Hi, I'm trying to use the McMillan python installer package
(http://www.mcmillan-inc.com/install1.html) on some sources
that use pygtk. I'm having some problems doing so. I was
wondering if anyone has gotten this to work in the past?
I'm aware that the installer requires me to specify which
imports are hidden in native C code. I believe I've caught
most of these (and handling some of them manually).. But..
after getting past that hurdle I'm seeing very weird behavior.
in libglade.c:pylibglade_register_classes there is a failure
during import:
if ((module = PyImport_ImportModule("gtk._gtk")) != NULL) {
PyObject *moddict = PyModule_GetDict(module);
_PyGtkWidget_Type = (PyTypeObject *)PyDict_GetItemString(moddict, "Widget");
if (_PyGtkWidget_Type == NULL) {
PyErr_SetString(PyExc_ImportError,
"cannot import name Widget from gtk._gtk");
return;
}
The "Widget" type is missing from the gtk._gtk module. In fact,
I did an inventory of the class and found of the 702 normal attributes,
there were only 569 present. The missing attributes are:
AccelGroup AccelLabel Accessible Adjustment Alignment Arrow
AspectFrame Bin Box Button ButtonBox Calendar CellEditable
CellRenderer CellRendererPixbuf CellRendererText CellRendererToggle
CheckButton CheckMenuItem CList ColorSelection ColorSelectionDialog
Combo Container CTree CTreeNode Curve Dialog DrawingArea Editable
[...]
TreeSortable TreeStore TreeView TreeViewColumn VBox VButtonBox Viewport
VPaned VRuler VScale VScrollbar VSeparator Widget Window WindowGroup
ie.. just about all of the widget types. I'm not too familiar with
the innards of pygtk (getting more familiar with it now). Does this
ring a bell to anyone? How is the process of defining this set of
attributes different than the rest of the pygtk attributes?
Any help or hints appreciated...

[pygtk] New FAQ: rendering computed TreeViewColumns
Hello!
New subscriber here; #pygtk's very own kiko suggested I contribute this
here after I got my answer, and let you work your magic so other people
might not ask this over and over again :)
It's easy to have a gtk.CellRendererText render an integer i from your
model, but it's not so easy to render f(i). In my case I wanted to
store file sizes (in bytes) as integers, but report them in ls -sh's
familiar xx.xM format.
The solution hinges around gtk.TreeViewColumn.set_cell_data_func, using
the -original- CellRendererText you supply to that column, and setting
the renderer's 'text' property.
Here's a quick and dirty example that kinda does an ls -shA . and
reports it in a list. I'm not sure why my sizes are somewhat off, but
that doesn't impact the relevent process. :)
-m
--
#! /usr/bin/env python
import pygtk
pygtk.require("2.0")
import gtk
# set_cell_data_func's callback - reads the size, sets the renderer
def render_filesize(column, cell, model, iter, renderer):
bytes = model.get_value(iter, 1)
if bytes < 1000: sizestr = str(bytes) + 'B'
elif bytes < 1000*2**10: sizestr = '%.2fK' % (bytes/2.0**10)
elif bytes < 1000*2**20: sizestr = '%.2fM' % (bytes/2.0**20)
elif bytes < 1000*2**30: sizestr = '%.2fG' % (bytes/2.0**30)
renderer.set_property('text', sizestr)
win = gtk.Window()
model = gtk.ListStore(str, int)
view = gtk.TreeView(model)
view.append_column(gtk.TreeViewColumn('File', gtk.CellRendererText(), text=0))
size_renderer = gtk.CellRendererText()
size_renderer.set_property('xalign', 1.0)
size_column = gtk.TreeViewColumn('Size', size_renderer, text=1)
# note that I carefully use the column's original renderer and I
# pass it as the user_data argument so the callback has it
size_column.set_cell_data_func(size_renderer, render_filesize, size_renderer)
view.append_column(size_column)
win.add(view)
win.show_all()
win.connect('delete-event', gtk.mainquit)
win.connect('destroy-event', gtk.mainquit)
# get some info to test it

for f in os.listdir('.'):
model.append((f, os.stat(f)[6]))
