Hi again,
ok, I found it.
Here you have the answer:
class IconView(gtk.Iconview):
def __init__(self):
...
crpb = gtk.CellRendererPixbuf()
self.pack_start(crpb, False)
self.set_cell_data_func(crpb, self.cell_pixbuf_func)
# self.set_text_column(6)
crtxt = gtk.CellRendererText()
crtxt.set_property('width', ITEM_WIDTH-10)
crtxt.set_property('ellipsize', pango.ELLIPSIZE_END)
crtxt.set_property('alignment', pango.ALIGN_CENTER)
crtxt.set_property('scale', 0.8)
self.pack_start(crtxt, False)
self.set_attributes(crtxt, text=6)
...
def cell_pixbuf_func(self, celllayout, cell, model, iter):
pb = get_cover(model.get_value(iter, 1), 'huge') # book file path
cell.set_property('pixbuf', pb)
Sorry for the noise,
