A frame consists of an arbitrary sequence of QTextBlocks and child QTextFrames. This class provides a way to iterate over the child objects of a frame, and read their contents. It does not provide a way to modify the contents of the frame.
Member Function Documentation
iterator::iterator(const iterator &other)
Copy constructor. Constructs a copy of the other iterator.
iterator::iterator()
Constructs an invalid iterator.
iterator &iterator::operator=(const iterator &other)
Assigns other to this iterator and returns a reference to this iterator.
QTextBlock iterator::currentBlock() const
Returns the current block the iterator points to. If the iterator points to a child frame, the returned block is invalid.
See also currentFrame().
QTextFrame *iterator::currentFrame() const
Returns the current frame pointed to by the iterator, or nullptr
if the iterator currently points to a block.
See also currentBlock().
iterator &iterator::operator++()
Moves the iterator to the next frame or block.
See also currentBlock() and currentFrame().
iterator &iterator::operator--()
Moves the iterator to the previous frame or block.
See also currentBlock() and currentFrame().
