Detailed Description

The QTextBlock::iterator class provides an iterator for reading the contents of a QTextBlock. A block consists of a sequence of text fragments. This class provides a way to iterate over these blocks and read their contents. It does not provide a way to modify the internal structure or contents of the block.

An iterator can be constructed and used to access the fragments within a text block in the following example.

QTextBlock::iterator iter;
 
for (iter = currentBlock.begin(); ! (iter.atEnd()); ++iter) {
   QTextFragment currentFragment = iter.fragment();
 
   if (currentFragment.isValid()) {
      processFragment(currentFragment);
   }
}

Constructor & Destructor Documentation

QTextBlock::iterator::iterator ( )

inline

Constructs an iterator for this QTextBlock.

QTextBlock::iterator::iterator ( const iterator & other )

default

Copy constructs a new QTextBlock::iterator from other.

QTextBlock::iterator::iterator ( iterator && other )

default

Move constructs a new QTextBlock::iterator from other.

Method Documentation

bool QTextBlock::iterator::atEnd ( ) const

inline

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

QTextFragment QTextBlock::iterator::fragment ( ) const

Returns the text fragment the iterator currently points to.

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

inline

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

iterator & QTextBlock::iterator::operator++ ( )

The prefix ++ operator advances the iterator to the next item in the hash and returns an iterator to the new current item.

++iter;

iterator QTextBlock::iterator::operator++ ( int )

inline

The postfix ++ operator advances the iterator to the next item in the text block and returns an iterator to the old current item.

iter++;

iterator & QTextBlock::iterator::operator-- ( )

The prefix -- operator makes the preceding item current and returns an iterator pointing to the new current item.

--iter;

iterator QTextBlock::iterator::operator-- ( int )

inline

The postfix -- operator makes the preceding item current and returns an iterator to the old current item.

iter--;

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

default

Copy assigns from other and returns a reference to this object.

iterator & QTextBlock::iterator::operator= ( iterator && other )

default

Move assigns from other and returns a reference to this object.

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

inline

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