Is the QStandarditemModel - finditems() fast?

[mohsen]

Does someone know about how finditems function in QStandardItemModel actually performs the process? I want to understand if it's safe to use and fast.
And in cases where only one record should be found, Is it better to use a "for" syntax through rows and compare data one by one? or finditems() function is more efficient?

well, why don't you check the source code to see how it is implemented?
