I am trying to get to grips with treeviews in pygtk/gtk and am stuck on setting the alignment of the columns.
No matter what I try I cannot change the alignment](*,)
Here is the code I found on the web which I am using to change different lines to see the effect and thus learn how they work. However I added the line self.cell1.set_property('alignment', pango.ALIGN_CENTER) and it makes no difference. I have tried right align too with no joy!
Can anyone help me please?

# Create a new window
self.window = gtk.Window(gtk.WINDOW_TOPLEVEL)
self.window.set_title("TreeViewColumn Example")
self.window.set_size_request(400, 200)
self.window.connect("delete_event", self.delete_event)
# create a liststore with one string column to use as the model
self.liststore = gtk.ListStore(str, str, str, 'gboolean')
# create the TreeView using liststore
self.treeview = gtk.TreeView(self.liststore)
# create the TreeViewColumns to display the data
self.tvcolumn = gtk.TreeViewColumn('Pixbuf and Text')
self.tvcolumn1 = gtk.TreeViewColumn('Text Only')
# add a row with text and a stock item - color strings for
# the background
