the tree view is not a toplevel widget ,so you have to pack it into a container to show it.In the callback of the button ,you create a new window ,and tree view,while you do not pack the tree view into the windows.
if you want the callback function of button to manipulate the treeview in the main window which the button is pack into,you can use the lookup_widget()function or g_object_set()and g_object_get() function,to obtain the pointer of the tree view in the main windows.
Generally there are 4 steps to use the treeview widget.
1.add data to Gtkliststore or Gtktreestore.
2.pack the GtktreeviewColumn into GTKtreeview
3.pack the Gtkcellrenderer into a GtktreeviewColumn
3.bind the data in Gtklist(tree)store with Gtkcellrenderer.

Based on what I see above, you create brand new treeview, and then never
pack it to any window, and never even show it. I guess what you actually
see on screen is an empty tree from a glade file. You have two
treeviews, one empty and one hidden! So you either have to go all the
way and create window which would hold the treeview in your code, or do
not call gtk_treeview_new at all and get the widget from the glade file
instead.

I want a simple gtk application that displays a popup or context menu with 3
entries when started.
There is a widget popup menu in gtk+ applications i added this widget but I
could not see any gui related to that. How to add and make it visibe.
