[Interest] QFileSystemModel

[Igor Mironchik]

Hi,

I derived from QFileSystemModel to have check boxes on files and 
directories. It works.

I want to recursively check all files and all directories within checked 
one, but rowCount() for checked directory returns 0 if this directory 
wasn't expanded in tree view.

I played with canFetchMore() and fetchMore(). It doesn't help.

How can I solve this problem?
