iterator露
- PyQt5.QtGui.QTextBlock.iterator
Description露
The 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, 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())
# #! [3] #! [5]
# processFragment(currentFragment);
# }
