Detailed Description

A block consists of a sequence of text fragments. This class provides a way to iterate over these, 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 way:


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

Member Function Documentation

QTextFragment iterator::fragment() const

Returns the text fragment the iterator currently points to.

iterator &iterator::operator++()

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

iterator &iterator::operator--()

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