iterator Class

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.

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.

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().

QTextFrame *iterator::parentFrame() const

Returns the parent frame of the current frame.

See also currentFrame() and QTextFrame::parentFrame().

bool iterator::operator!=(const iterator &other) const

Retuns true if the iterator is different from the other iterator; otherwise returns false.

iterator &iterator::operator++()

Moves the iterator to the next frame or block.

See also currentBlock() and currentFrame().

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.

See also currentBlock() and currentFrame().

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

Retuns true if the iterator is the same as the other iterator; otherwise returns false.
