How to delete PyGTK ComboBox entries?

[=?ISO-8859-15?Q?Ma=EBl_Benjamin_Mettler?=]

Hello list!

I need to repopulate PyGTK ComboBox on a regular basis. In order to do
so I have to remove all the entries and then add the new ones. I tried
to remove all entries like that:

def clear_comboboxe s(boxreference) :
try:
while True:
boxreference.re move_text(0)
except:
pass

And then repopulate by iterating through the list of desired entries and
calling ComboBox.append _text(text). It works, but is painfully
sloooooooow! Is there a faster way to completely change the entries in a
ComboBox, by using an all erase method or overwriting the container
object? I haven't found anything with google, as the searches are too
ambiguous to yield usable results.

Thanks,

Maël

model = combo_box.get_m odel()
combo_box.set_m odel(None)
model.clear()
for entry in desired_entries :
model.append([entry])
combo_box.set_m odel(model)

model.append is essentially the same as combo_box.appen d_text. Setting
the model to None before making changes to it speeds things at least in
the case of tree views. I'm not sure if it does much with combo boxes.
If you experince speed issues with combo boxes you're either doing
something very wrong or you have so many entries that you ought to be
using a tree view instead.

Hej!

model = combo_box.get_m odel()
combo_box.set_m odel(None)
model.clear()

model.append([entry])

Works like a charm. Thanks a lot!
