Hi,
I want to color single cells in a TreeView (totals of a table).
Since I'm using cell_data_func to set value of property text I tried
using that same function to set colors but it turns out all cells get
colored...
def dict_cell_data_func(self, column, cell, model, iter, (col_num, name)):
obj = model.get_value(iter, col_num)
value = getattr(obj, name)
cell.set_property("text", value)
if value == 'venice':
cell.set_property("cell-background", 'yellow')
can anybody help me understanding why?
I attach the complete example.
thanks in advance

import gtk
import sys
class A(object):
def __init__(self, name):
self.name = name
class Tree(object):
def __init__(self):
window = gtk.Window()
self.model = gtk.ListStore(object)
tree_view = gtk.TreeView(self.model)
window.add(tree_view)
window.show_all()
renderer = gtk.CellRendererText()
column = gtk.TreeViewColumn("Foo", renderer)
column.set_cell_data_func(
renderer, self.dict_cell_data_func, (0, 'name'))
tree_view.append_column(column)
self.fill_model()
def dict_cell_data_func(self, column, cell, model, iter, (col_num, name)):
obj = model.get_value(iter, col_num)
value = getattr(obj, name)
cell.set_property("text", value)
if value == 'venice':
cell.set_property("cell-background", 'yellow')
def fill_model(self):
cities = 'rome venice florence'
for city in cities.split():
self.model.append( [ A(city) ] )
try:
Tree()
gtk.main()
except KeyboardInterrupt:
sys.exit()
