Detailed Description#

A frame consists of an arbitrary sequence of QTextBlock s and child QTextFrame s. 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.

__init__()#

Constructs an invalid iterator.

__iter__()#

Return type:: object

__next__()#

Return type:: object

atEnd()#

Return type:: bool

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

currentBlock()#

Return type:: QTextBlock

Returns the current block the iterator points to. If the iterator points to a child frame, the returned block is invalid.

currentFrame()

currentFrame()#

Return type:: QTextFrame

Returns the current frame pointed to by the iterator, or None if the iterator currently points to a block.

currentBlock()

__ne__(o)#

Parameters:: o – iterator
Return type:: bool

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

__iadd__()#

Return type:: iterator

Moves the iterator to the next frame or block.

currentBlock() currentFrame()

__iadd__(arg__1)

Parameters:: arg__1 – int
Return type:: iterator

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

__isub__()#

Return type:: iterator

Moves the iterator to the previous frame or block.

See also

currentBlock() currentFrame()

__isub__(arg__1)

Parameters:: arg__1 – int
Return type:: iterator

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

__eq__(o)#

Parameters:: o – iterator
Return type:: bool

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

parentFrame()#

Return type:: QTextFrame

Returns the parent frame of the current frame.
