PyQt QCompleter model

[nusch]

The following code:


strings=["asdad", "baasd", "casd", "caxd"]
completer = QCompleter(strings)
model = completer.model()
print model.rowCount()
model.stringList().append("test")
print model.rowCount()


prints 4 before and after appending test to stringList. What should I
do to let the model know about new data? I can save reference to
model.stringList() append keyword and after pass this reference as an
argument to setStringList then last model.rowCount() increases, but it
is not efficient when operating with e.g 20000 words in such list.

Is there better way to do this? Or is there any other method with
simply allow to add word to Qcompleter without using .stringList() >

The following code:

strings=["asdad", "baasd", "casd", "caxd"]
completer = QCompleter(strings)
model = completer.model()
print model.rowCount()
model.stringList().append("test")

This may not work as you expect. Although it may actually modify the list,
the model won't know about the change.

print model.rowCount()

prints 4 before and after appending test to stringList. What should I
do to let the model know about new data? I can save reference to
model.stringList() append keyword and after pass this reference as an
argument to setStringList then last model.rowCount() increases, but it
is not efficient when operating with e.g 20000 words in such list.

Ideally, you would call setStringList(), but I can see why that isn't a
good solution for you.

Use the model API to append new rows and set new data. Something like
this should get you started:

rows = model.rowCount()
if model.insertRow(rows):
index = model.index(rows)
model.setData(index, QVariant("test"))
