<p>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.</p>
<p>An iterator can be constructed and used to access the fragments within a text block in the following way:</p>
<pre> QTextBlock.iterator it;
for (it = currentBlock.begin(); !(it.atEnd()); ++it) {
QTextFragment currentFragment = it.fragment();
if (currentFragment.isValid())
processFragment(currentFragment);
}</pre>
