* Filter by regex in string view * Dont recompile the regex for every string, display error message * localization * Use data->Buf for pattern creation / searching The filter string seems to get updated after the callback finished. Therefore the search string was always 1 character behind the actual string in the textfield when calling find() / creating the regex.
