Re: How to set focus on a text view when tree selection changed?

[smartkenny <smartkenny gmail com>]

Hello, Milosz

Thank you for answer my question. But it doesn't work. Here's my program:


#!/usr/bin/env python

import pygtk
pygtk.require('2.0')
import gtk


def wrap(widget):
   sw = gtk.ScrolledWindow()
   sw.add(widget)
   sw.set_policy(gtk.POLICY_AUTOMATIC, gtk.POLICY_AUTOMATIC)
   sw.set_shadow_type(gtk.SHADOW_ETCHED_IN)
   sw.set_border_width(1)
   return sw



def on_selection_changed(selection):
   selection.get_tree_view().grab_focus()


if __name__ == "__main__":
   paned = gtk.HPaned()
  
   treestore = gtk.TreeStore(str)
   new_iter = treestore.append(None)
   treestore.set(new_iter, 0, '00000')
   new_iter = treestore.append(None)
   treestore.set(new_iter, 0, '11111')
   new_iter = treestore.append(None)
   treestore.set(new_iter, 0, '22222')
   new_iter = treestore.append(None)
   treestore.set(new_iter, 0, '33333')
   new_iter = treestore.append(None)
   treestore.set(new_iter, 0, '44444')
  
   treeview = gtk.TreeView(treestore)
   treeview.set_enable_search(False)
   treeview.get_selection().connect_after('changed', on_selection_changed)
   column = gtk.TreeViewColumn();
   renderer = gtk.CellRendererText()
   column.pack_start(renderer, False)
   column.add_attribute(renderer, 'text', 0)
   treeview.append_column(column)
   paned.add1(wrap(treeview))
  
   textview = gtk.TextView()
   paned.add2(wrap(textview))
   paned.set_position(250)
  
   window = gtk.Window(gtk.WINDOW_TOPLEVEL)
   window.set_default_size(800, 600)
   window.add(paned)
   window.show_all()
  
   gtk.main()


Thank you!

Kenny
