Detailed Description

This iterator class provides an iterator for reading the contents of a QTextFrame.

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.

Constructor & Destructor Documentation

QTextFrame::iterator::iterator ( )

Constructs an invalid iterator.

QTextFrame::iterator::iterator ( const iterator &  other)

Copy constructor. Constructs a copy of the other iterator.

Method Documentation

bool QTextFrame::iterator::atEnd ( ) const
inline

Returns true if the current item is the last item in the text frame.

QTextBlock QTextFrame::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 * QTextFrame::iterator::currentFrame ( ) const

Returns the current frame pointed to by the iterator, or 0 if the iterator currently points to a block.

See also
currentBlock()
bool QTextFrame::iterator::operator!= ( const iterator &  other) const
inline

Returns true if the iterator is different from the other iterator, otherwise returns false.

iterator & QTextFrame::iterator::operator++ ( )

Moves the iterator to the next frame or block.

See also
currentBlock(), currentFrame()
iterator QTextFrame::iterator::operator++ ( int  )
inline

The postfix ++ operator (i++) advances the iterator to the next item in the text frame, and returns an iterator to the old item.

iterator & QTextFrame::iterator::operator-- ( )

Moves the iterator to the previous frame or block.

See also
currentBlock(), currentFrame()
iterator QTextFrame::iterator::operator-- ( int  )
inline

The postfix – operator (i–) makes the preceding item in the current frame, and returns an iterator to the old item.

iterator & QTextFrame::iterator::operator= ( const iterator &  other)

Assigns other to this iterator and returns a reference to this iterator.

bool QTextFrame::iterator::operator== ( const iterator &  other) const
inline

Returns true if the iterator is the same as the other iterator, otherwise returns false.

QTextFrame * QTextFrame::iterator::parentFrame ( ) const
inline

Returns the parent frame of the current frame.
