hi...

i want to filter a filtered QSortFilterProxyModel..

for example items such this :

proxyModel items =
"123a"
"1234a"
"12345"
"1234567"
"12345678a"
....
result proxyModel->setFilterRegExp(regExp("12345")) =

"12345"
"1234567"
"12345678a"

now i want to filter just tree above item with proxyModel->setFilterRegExp(regExp("a"))

i want the result just be "12345678a" no "1234a" and "12345678a"
