It would certainly be possible to write a CList-compatible Treeview wrapper in Python that took care of the gory details for you (without slowing it down in any way significant IMO); I think that's something that's definitely missing. You say you have a sorting problem with Treeview that doesn't exist in CList -- can you be more specific about that?

Strictly speaking, GTK+ doesn't have a listview. It has a single TreeView widget that can be associated with a tree model or a list model. The standard list model in GTK+ is the ListStore. This means that from the TreeView side, a 2-column list looks exactly like a 2-column tree. The TreeView and TreeColumns are set up the same in either case. The only difference is in the type of model you use. There is some help available in the pygtk FAQ. If you search the FAQ for "ListStore" you'll get several hits. All of them are worth reading. (Actually it's worthwhile to read the entire FAQ section on TreeView.) FAQ 13.6 How do I put icons in a TreeView? provides a simple complete example using a ListStore. You can find another example in the pygtk distribution itself in examples/pygtk-demo/demos/list_store.py If you find these examples lacking let us know how they can be improved. Maybe new examples should be added. ___ 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] PyGTK + glade + freeze
Hi PyGTKkers -- I have written a PyGTK app using glade, and am now trying to freeze it. I installed the freeze package from Python 2.2.3, and build the executable using the instructions included in the README. However, when I run the executable, it throws an exception when I do "import pygtk" and/or "import glade". The app works fine when run as a Python script. While investigating this problem, I have learned that freeze isn't that useful when your app calls shared libraries. Therefore, I have tried rebuilding everything -- PyGTK and Python -- using static libs, and have tried static links to their .a libraries. HOwever, this still doesn't work. Questions: * Are there any useful docs on the web discussing specifically how to freeze PyGTK apps? I've Googled around, but haven't found anything specific to PyGTK. * Does anybody know if Tkinter is lurking around in the background of GTK? I have read a lot about TCL/Tk problems encountered while freezing Python apps. If this stuff is not used by GTK, I will just try deleting it from my -L path 'cause it's a .so. * Has anybody here frozen a PyGTK app? Do you have any pointers, suggestions, or things to look for?

isnt a listview just a treeview with a ListModel ?
model = gtk.ListStore(gobject.TYPE_STRING, gobject.TYPE_STRING)
view = gtk.TreeView()
view.set_model(model)
cell0 = gtk.CellRendererText()
col0 = gtk.TreeViewColumn("stuff", cell0, text = 0) # number of the
column in the model
view.append_column(col0)
cell1 = gtk.CellRendererText()
col1 = gtk.TreeViewColumn("stuff2", cell1, text = 1) # number of the
column in the model
view.append_column(col1)
iter = model.append(None)
model.set_value(iter, 0, "stuff")
model.set_value(iter, 1, "there")
sw = gtk.ScrolledWindow()
sw.set_policy(gtk.POLICY_NEVER, gtk.POLICY_AUTOMATIC)
sw.add(view)
sw.show_all()
# add sw to your window
Or am I missing something ? :)

[pygtk] CList
I know that the CList widget is deprecated in pygtk2, but does anyone know how long it will actually be around? The reason I ask is that I am having lots of trouble duplicating it's functionality and speed using the TreeView widget. I have been attempting to do this ever since the TreeView widget came out. Every few months, I grab the latest version of pygtk and attempt to duplicate the CList functionality using TreeView, but to no avail. I have done a lot of reading, attempted to use Liststore/TreeModelSort/TreeView combinations, read up on how to handle large datasets, etc.. Not only does this seem WAY more complicated than it needs to be, it also is slower than the CList. 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. 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. Anyway, sorry to rant. I really just want to know how long I can count on CList being in pygtk2. CList is a great widget and it handles all of my needs just fine. Thanks.

[pygtk] PyGTK reference, set_search_equal_func, set_search_column
I recently used the treeview.set_search_equal_func(func) for the first time and found its behavior somewhat counterintuitive. The function you hand it needs to return false for a match and true for a non-match. It struck me that this would be worth adding to the pygtk reference entry for that function. Another question: can anyone think of how one might break set_search_column(). In my app I couldn't get it to work correctly (the search column remained 0 even when I called tv.set_search_column(3). Anyway, when I tried to cook up a simple example, I couldn't reproduce the behavior. I don't begin to understand where my code could have thrown this off -- needless to say, the function tv.set_search_column(0) appears nowhere in the program. It's not urgent -- I used set_search_equal_func() instead and that works (and gave me some additional control over the interactive search). Thanks for any thoughts, and thanks to John Finlay for maintaining the excellent docs.
