QTextBlock.iterator ¶

概要 ¶

详细描述 ¶

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);
}

PyObject

PySide2.QtGui.QTextBlock.iterator. __next__ ( ) ¶

返回类型

PyObject

PySide2.QtGui.QTextBlock.iterator. atEnd ( ) ¶

PySide2.QtGui.QTextBlock.iterator. __ne__ ( o ) ¶

参数

o – iterator

返回类型

bool

Retuns true if this iterator is different from the other iterator; otherwise returns false .

PySide2.QtGui.QTextBlock.iterator.operator++(arg__1)

参数

arg__1 – int

返回类型

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.

PySide2.QtGui.QTextBlock.iterator.operator--(arg__1)

参数

arg__1 – int

返回类型

iterator

The postfix – operator ( i-- ) makes the preceding item current and returns an iterator to the old current item.

PySide2.QtGui.QTextBlock.iterator. __eq__ ( o ) ¶

参数

o – iterator

返回类型

bool

Retuns true if this iterator is the same as the other iterator; otherwise returns false .
