iterator Class

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);
     }
