i want to store items in a gtk-list and i decided to use the Gtk TreeView as List. Because i am quite new to python and gtk i want to store my elements as string representation in the TreeView and in a seperate python-list the according objects.
So if i delete an item in the Gtk list (via key-event), i have to be able to determine the selected row index to delete the correct python-list element.
My actual question is: How can i determine the index of the selected row in a Gtk.TreeView?
Thank you for your help!
PS: I am using Python 3 with GTK 3
Use Gtk.TreeViewSelection. You can get it from Gtk.TreeView (Assuming you have id column in your GtkTreeModel (GtkListStore or GtkTreeStore) constructor).
from gi.repository import Gtk
def yourcallback ( selection ):
model,list_iter = selection.get_selected ()
if list_iter != None:
# Debugging mode, uncomment to activate
# print "row index = " + model[list_iter][column_number_that_you_want]
# alternate
# def yourcallback (path, column, data):
# ........
..........
yourtvselection = yourtv.get_selection ()
yourtvselection.connect ( "changed" , yourcallback)
# alternative signal
# yourtv.connect ("row-activated", yourcallback)
