Member Function Documentation

advance() [1/2]

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). The iterators are stored in a vector.

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 vector
• B's iterator is processed (vector.back()) first; then the loop goes back to processing A's iterator

beginIterating() [1/2]

void QDirListingPrivate::beginIterating

(

)

Resets the iteration state (if any), so that calling begin()/cbegin() always starts iterating anew.

This function 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.
