[maemo-developers] GtkTreeView issue

[From: Matt Clark]

I thought before I submit a bug I'd see if anyone can point out where  
I'm going wrong.  My problem is that in an app I'm developing I'm not  
getting row-activated signals from a GtkTreeView under pygtk on an  
N800, but they work fine under pygtk elsewhere (e.g. Ubuntu Feisty  
(python 2.5.1), or OS X/Fink (python 2.4.2)).  The N800 is latest  
firmware with no changes except the addition of the latest osso- 
xterm, python2.5-runtime and dropbear.

Sample code follows, and is runnable on maemo or on stock GTK.

Thanks

Matt

def activation_callback(treeview, path, view_column):
     print 'You will not see this output on an N800'
     print 'But you will on Ubuntu and OS X'
     model = treeview.get_model()
     iter = model.get_iter(path)
     val = model.get_value(iter, 0)
     print 'Value of first item in row is %s' % val

store = gtk.TreeStore(str)
parentiter = store.append(None, ['parent item 0'])
childiter = store.append(parentiter, ['child item 0'])

view = gtk.TreeView(model = store)
cellrenderer = gtk.CellRendererText()
column = gtk.TreeViewColumn('Column', cellrenderer, text=0)
view.append_column(column)
view.connect("row-activated", activation_callback)

window.add(view)

view.expand_all()
view.show_all()
window.show()

gtk.main()
