QTextBlock.iterator 类提供迭代器用于读取内容在 PySide.QtGui.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())
processFragment(currentFragment);
}

返回迭代器目前指向的文本片段。
| 参数： | o – PySide.QtGui.QTextBlock::iterator |
|---|---|
| 返回类型： | PySide.QtCore.bool |
Retuns true if this iterator is different from the other iterator; otherwise returns false.
| 参数： | arg__1 – PySide.QtCore.int |
|---|---|
| 返回类型： | PySide.QtGui.QTextBlock::iterator |
The postfix ++ operator ( i++ ) advances the iterator to the next item in the text block and returns an iterator to the old current item.
| 参数： | arg__1 – PySide.QtCore.int |
|---|---|
| 返回类型： | PySide.QtGui.QTextBlock::iterator |
The postfix – operator ( i-- ) makes the preceding item current and returns an iterator to the old current item.
| 参数： | o – PySide.QtGui.QTextBlock::iterator |
|---|---|
| 返回类型： | PySide.QtCore.bool |
Retuns true if this iterator is the same as the other iterator; otherwise returns false.
