QTreeWidgetItemIterator ¶

概要 ¶

详细描述 ¶

迭代器将按预定次序的遍历顺序走查项，从而拜访父级节点 before 它继续到子级节点。

例如，以下代码范例中的每一树项，对照用户指定的搜索字符串校验首列文本：

it = QTreeWidgetItemIterator(treeWidget)
while it:
    if it.text(0) == itemText:
        *it.setSelected(True)
    ++it
											

还可以过滤出某些类型的节点，通过传递某些 flags to the constructor of QTreeWidgetItemIterator .

IteratorFlags

构造迭代器为给定 widget 使用指定 flags to determine which items are found during iteration. The iterator is set to point to the first top-level item contained in the widget, or the next matching item if the top-level item doesn’t match the flags.

IteratorFlag

构造迭代器为给定 item 使用指定 flags to determine which items are found during iteration. The iterator is set to point to item , or the next matching item if item doesn’t match the flags.

IteratorFlag

构造迭代器为相同 QTreeWidget as it . The current iterator item is set to point on the current item of it .

这些标志可以被传递给 QTreeWidgetItemIterator 构造函数 (OR 到一起若使用一个以上)，以便迭代器将仅迭代匹配给定标志的项。

返回类型

PyObject

PySide2.QtWidgets.QTreeWidgetItemIterator. __next__ ( ) ¶

返回类型

PyObject

PySide2.QtWidgets.QTreeWidgetItemIterator. __iadd__ ( n ) ¶

参数

n – int

返回类型

QTreeWidgetItemIterator

Makes the iterator go forward by n matching items. (If n is negative, the iterator goes backward.)

If the current item is beyond the last item, the current item pointer is set to None 。返回结果迭代器。

PySide2.QtWidgets.QTreeWidgetItemIterator. __isub__ ( n ) ¶

参数

n – int

返回类型

QTreeWidgetItemIterator

Makes the iterator go backward by n matching items. (If n is negative, the iterator goes forward.)

If the current item is ahead of the last item, the current item pointer is set to None 。返回结果迭代器。
