Member Function Documentation

advance()

void QDirListingPrivate::advance

(

)

Advances the internal iterator, either a QAbstractFileEngineIterator (e.g. QResourceFileEngineIterator) or a QFileSystemIterator (which uses low-level system methods, e.g. readdir() on Unix).

An iterator stack is used for holding the iterators.

A typical example of doing recursive iteration:

• while iterating directory A we find a sub-dir B
• an iterator for B is added to the iterator stack
• B's iterator is processed (the top() of the stack) first; then loop goes back to processing A's iterator

This functions returns true if the current entry matches the filters (i.e., the current entry will be returned as part of the directory iteration); otherwise, false is returned.
