[pygtk] problem with TreeView + ListStore

[Guillermo Heizenreder]

Hi list
I'm developing a application for learn pygkt, and I need to know when a
user selected or clicked one determinate row of my TreeView for shot
another signal .

Study the tutorial [1] I began to see the explanation that I see in the
chapter 14.7. TreeView Signal and found one in particular
"select-cursor-row", but I don't understood how implementing.

Something like that.
if user_selected_row:
self.hbox_118.show()
print "YES"

NOTE: self.hbox_118 = wTree.get_widget("hbox118")

Thank and Regard

Hi,

Well, ignoring the rest of the post, I can tell you that the usual way
of
doing this is to connect the changed signal of the treeview's
selection.

This explains it better than I would:

http://faq.pygtk.org/index.py?req=show&file=faq13.011.htp

Now to complete your actual use case:

def on_selection_changed(selection, *args):
model, paths = selection.get_selected_rows()
if paths:
hbox.show()

treeView = gtk.TreeView()
selection = self.treeView.get_selection()
selection.connect('changed', on_selection_changed)

There are some situations where you may want to actually connect the
mouse click event, and we can discuss them further if you require.

I should of course mention kiwi.ui.objectlist.ObjectList. It is an
easier to use abstraction over TreeView, and has helped me in every
situation where I would use a TreeView.
