You can use a tuple in your dic. See

I can load over 13000 items into my ListStore in a few seconds on an AMD64, and about 10 seconds on a 1.5GHz G4. And this is appending python objects (dictionaries), using a data_func to render them, and with column autosizing turned on. Could you give us a few more details about what kind of objects you are loading into your ListStore and how you are loading them? Are you doing anything in between appends?

Not only does this seem WAY more complicated than it needs to be, it also is slower than the CList. How large are the datasets we're talking about here, just so we have a reference? Basically, I use the CList as a multi-column listbox to show rows from a database. I know that this can easily be done using TreeView. Where it gets complicated is when you want to sort the TreeView or refresh the data from the database and you want the current sort and selected record to be shown. In other words, when I refresh the view or when I return to the view from editing a single record, I want it to be sorted the same way it was, with the same selected record showing. First, it's essential to keep clear the distinction between the view and the model (ListStore in this case). When you say refresh the view, do you mean is that you're clearing the model and reloading the data into it? You shouldn't need to do this very often. When you make changes to the model, they should be automatically reflected in the view. How are you writing the data to the model? Also, it would help to see some code. Dave Cook This is very complicated using TreeViews, especially because I have resorted to using TreeModelSort in order to try and speed up the very slow sort times when refreshing data in a view.

Attached is a GenericCellRenderer that I used in my Classicollect app
(ripped out of context and simplified a bit), but not shown is the important
part where you have to take care of sending all the
row-insert/changed/deleted etc. signals. Note that it doesn't do the
subclassing quite correctly. I could fix this up into a simple working
example if anyone is interested.
Essentially I implemented this tree (really a forest) the way we were taught
in school: each tree node has its cargo, a reference to the parent node, and
a list of child nodes.
I also keep an index for each node, which is its position its parent's child
list, for efficiently finding the path of a node. Since get_path doesn't
seem to get called much (by treeviews anyway), this may not be necessary,
and it does add some extra bookkeeping if you remove or insert nodes.
I originally wrote this because I didn't know about
TreeViewColumn.set_cell_data_func, and, well, writing a GTM is kinda fun.
Then I went back to it when I found that cell_data_funcs wouldn't work with
interactive searches (there was no TreeView.set_search_func in pygtk at the
time; when I found out about that it was fixed by gjc within the day!) or
with the new ComboBoxes. Now with TreeModelFilter, I don't think I have any
need for a generic TreeModel, though I haven't had a chance to really test
it with a large data set. And if this works:

[pygtk] Fun with TreeModelFilter
This class solved a problem that has been bothering me for a long time: how to do interactive searches when your store contains only objects. The TreeView wants to access a column of strings to do this. Also, the new ComboBoxEntry can use a TreeModel, but again it wants to access a column directly to get its text. This is where TMF comes in. Not only can you filter a model, but it also lets you synthesize completely new columns. Jon Finlay's amazing tutorial does a good job covering TMF: http://tinyurl.com/2qjn9 The other solutions I came up with were writing a custom TreeModel (requires keeping track of a lot), and keeping a redundant string column that is kept synchronized with the object column using the Observer pattern. And here's some code showing how TMF can be used in this case: import gtk class Node(object): def __init__(self, name): self.name = name def __str__(self): return self.name def modify_func(model, iter, col): child_iter = model.convert_iter_to_child_iter(iter) child_model = model.get_model() return child_model.get_value(child_iter, 0) def print_nodes(model): it = model.get_iter_first() while it: print model.get_value(it, 0), repr(model.get_value(it, 1)) it = model.iter_next(it) store = gtk.ListStore(object) # ModelFilter synthesizes a string column using the modify func. # This string column can be used for interactive searches and ComboBoxes. filtered = store.filter_new() filtered.set_modify_func((str, object), modify_func) # put objects in the store nodes = map(Node, ['larry', 'bill', 'scott']) for node in nodes: it = store.append() store.set_value(it, 0, node) print_nodes(filtered) # modify the objects for node, name in zip(nodes, ['guido', 'linus', 'james']): node.name = name # does the ModelFilter track our changes? print_nodes(filtered) ___ pygtk mailing list [EMAIL PROTECTED] http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://www.async.com.br/faq/pygtk/

I want to remove the row that has been selected by the user. How do I proceed? How do I obtain the iter that points to the currently selected item? It must be easy, but I cannot find the function that would return the iter. TreeView contains a selection object that manages user selections. You need to get the selection object, then query it for the selected path with the get_selected() method. For single selection mode: selection = treeview.get_selection() result = selection.get_selected() if result: #result could be None model, iter = result model.remove(iter) For multiple selection mode you need to use a little hack to get the selected paths until get_selected_rows() is implemented (2.2 API): rows = [] selection.selected_foreach(lambda model, path, iter: rows.append(path)) rows will then be a list of selected paths, and you can use model.get_iter(path) to get the iters. Note that this hack will work with either selection mode, so I use it everywhere instead of get_selected().

A working tree example would be ideal.
There's a tutorial here:
http://liw.iki.fi/liw/texts/gtktreeview-tutorial.html
Don't forget the examples that come with the pygtk distribution. I whipped
up my own example of a multi-column treeview. It demonstrates a few things:
* How make certain cells editable. Here I use two control columns
at the end of my row (store column 2 3) that control whether a cell
is editable and visible. How the renderer uses these columns is set with
column = gtk.TreeViewColumn(column_titles[i], cell, text=i,
editable=ncols+i, visible=ncols+i)
which means that the renderer will get the text to render from column i
and determine whether the cell is editable and visible using the
values in column ncols+i. See the properties for the different
renderers to see what other keywords you can use.
* A callback for the edited signal which actually sets the new text
that you type in a cell. I use set_data/get_data to retrieve the
actual store column that the renderer corresponds to (you could also
pass it as user_data when connecting the callback).
* How to get a selection, this is in the on_delete_button_clicked callback.

[pygtk] Problem with stock icons on Mandrake 9.1 not showing up
I've been testing an application (created with glade2 on RH 9) on various distros and on Mandrake 9.1 I have a problem with stock icons in my toolbar not showing up (such as gnome-stock-midi, gnome-stock-mic, and gnome-stock-attach, and gnome-stock-text-bulleted-list). I also get the warning: (glade-gnome-demo:15363): GLib-GObject-WARNING **: gobject.c:946: object class GnomeProgram' has no property named default-icon' I also tested by mocking up a gnome app with the glade2 in Mandrake and adding toolbar buttons with those stock icons. Same problem, despite that fact that the icons are visible in glade. I'm using the gnome libs that Mandrake 9.1 comes with, but gnome-python from CVS. Any ideas on this one?

Q: Do I need to parse the glade file in every class ?
You could do this, or you could pass the XML object around, or you could get
the widgets you need in one place and pass them to where they are needed.
xml = gtk.glade.XML(GLADEFILE)
foo_widget = xml.get_widget('foo')
baz_object = Baz(foo_widget)
xml.signal_autoconnect(baz_object)
With what
parameters ? How do I get a class for the app1, one for about2 and one
for window1 ?
Just use get_widget to get these widgets from the tree by name. Gtk is not
a framework like Qt; you don't sublcass any framework classes.
Q: What restrictions do I have to consider when setting the callback
names in glade ? What is the scope of handler names defined in Glade ?
There is just one namespace, so you do have to be careful to use unique
names for things you want to be unique.
Can I use the same handler name for different handler in different
objects ?
http://www.async.com.br/faq/pygtk/index.py?req=showfile=faq03.001.htp
Is the 'delete' handler for clicked on button4 different from
that defined for window1 or are they the same ?
If you give then the same name, 'delete', the handlers are the same. The
names aren't qualified in the glade file.
You *can* use the same name for the handler. Howerver, whatever callback
you connect to the handler will get called when either signal is emitted.
If that's not what you intend, give the handlers unique names (if you give
your widgets unique names, this is the default behavior.)
Is the 'delete' handler
for app1 different from that for 'delete' handler for window1 ?
Ditto. But, again, by default these will be given different handler names:
'on_app1_delete_event' and 'on_window1_delete_event'.
Q: Can I turn the notebook1 and notebook2 into custom classes ? How do I
do that ?
I think you mean objects rather than classes, right? (Unless you do want
different behavior for each notebook).
You can't inherit from already existing widget objects, but you can use
aggretation or delegation:
class NotebookController(object):
def __init__(self, notebook):
self.notebook = notebook
...
def foo(self, bar):
self.notebook.foo(bar)
notebook1 = NotebookController(xml.get_widget('notebook1'))
Can I use handlers defined in glade in my custom classes ?
Sure, see the FAQ entry above for one way to do it.

Re: [pygtk] Treeview with boolean checkboxes

I have a project where I am using a treeview where one of the columns is
a boolean (check box) field. The behaviour I want is for only one check
box to be checked at any time. So if the user checks row 2 and then
checks row 8, row 2 is automatically unchecked. Is there a
gtkTreeViewColumn setting that will set the functionality or is it
something I will have to do manually?
What you want are radio buttons. I haven't tried this, but from the docs,
it looks like you would use radio instead of active when adding a column:
cell = gtk.CellRendererToggle()
tvcolumn = gtk.TreeViewColumn('foo', cell, radio=RADIOCOLUMN)
However, it's not clear to me whether the radio buttons have to be grouped
or whether this does it for you. See the FAQ:

Re: [pygtk] Should PyGtk be proposed for the Python 2.4 release?
On Mon, Mar 24, 2003 at 02:52:32AM -0500, Eric S. Raymond wrote: The biggest weakness of PyGTK at this moment is woefully inadequate documentation. The API documentation is simply not up to the standard of detail and clarity expected in a Python standard library. Tkinter was part of the standard library *long* before there was adequate documentation for it. There is still not much in the standard library docs. This is no excuse for the present situation with pygtk, but it does indictate that standards for inclusion in the library have not always been that stringent.
