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 stack.

A typical example of doing recursive iteration:

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

◆ advance() [2/2]

void QDirListingPrivate::advance ( )

◆ beginIterating() [1/2]

void QDirListingPrivate::beginIterating ( )

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