I've had a steep learning curve and so far, a combination of the tutotial, the reference and the FAQ have answered all the questions I've had. And as for finding them - a google search for "pygtk" brings up the tutorial (at moeraki.com) and the FAQ on the first page. A link from the tutorial to the reference would be nice though.

I wonder if you mean http://www.async.com.br/faq/pygtk/index.py?req=show&file=faq13.008.htp -- ? If so, it would be nice to know what was hard to understand in the example.

If there's no selection only the treeiter is None. The model will always be returned. Try this instead: selection = treeview.get_selection() model, treeiter = selection.get_selected() # If there's no selection, treeiter will be None if treeiter is not None: model.remove(treeiter) As David warns, the 'selection-changed' signal will be emitted sometimes when there's no current selection. You should always test before you try to use the selection. ___ pygtk mailing list [EMAIL PROTECTED] http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://www.async.com.br/faq/pygtk/

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().

[pygtk] How to remove a row from a GTK.ListStore?
Greetings. Newbie here. I tried to figure out how to remove a row from a GTK.ListStore on the web (documentation and mailing list archives), but I could not figure it out. The documentation is pretty poor. What I want to figure out is how can I get the iter required by GTK.ListStore.remove()? I have a GTK.TreeView with at GTK.ListStore as a Model. 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. On a different note, if I want to remove a row containing the String "blahblah" from a GTK.ListStore, how would I proceed? My main problem is that I cannot figure out how to create an iter. It is being required many places, but I cannot put my hand on how to create one which would point to the data I would desire.
