Detailed Description▲
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▲
[constexpr] iterator::iterator()▲
Constructs an invalid iterator.
bool iterator::atEnd() const▲
Returns true if the current item is the last item in the text frame.
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.

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▲
See also currentBlock()
QTextFrame *iterator::parentFrame() const▲
Returns the parent frame of the current frame.

bool iterator::operator!=(const iterator &other) const▲
Returns true if the iterator is different from the other iterator; otherwise returns false.
iterator &iterator::operator++()▲
iterator iterator::operator++(int)▲
The postfix ++ operator (i++) advances the iterator to the next item in the text frame, and returns an iterator to the old item.
iterator &iterator::operator--()▲
Moves the iterator to the previous frame or block.

iterator iterator::operator--(int)▲
The postfix – operator (i--) makes the preceding item in the current frame, and returns an iterator to the old item.
bool iterator::operator==(const iterator &other) const▲
Returns true if the iterator is the same as the other iterator; otherwise returns false.
