QTreeWidgetItemIterator ¶

概要 ¶

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 PySide.QtGui.QTreeWidgetItemIterator .

class PySide.QtGui. QTreeWidgetItemIterator ( widget [ , flags=QTreeWidgetItemIterator.All ] ) ¶

class PySide.QtGui. QTreeWidgetItemIterator ( item [ , flags=QTreeWidgetItemIterator.All ] )

class PySide.QtGui. QTreeWidgetItemIterator ( it )

参数：	flags – `PySide.QtGui.QTreeWidgetItemIterator.IteratorFlags` item – `PySide.QtGui.QTreeWidgetItem` widget – `PySide.QtGui.QTreeWidget` it – `PySide.QtGui.QTreeWidgetItemIterator`

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

PySide.QtGui.QTreeWidgetItemIterator. IteratorFlag ¶

这些标志可以被传递给 PySide.QtGui.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。

PySide.QtGui.QTreeWidgetItemIterator. __iter__ ( ) ¶

返回类型：	`PyObject`

PySide.QtGui.QTreeWidgetItemIterator. __next__ ( ) ¶

返回类型：	`PyObject`

PySide.QtGui.QTreeWidgetItemIterator. matchesFlags ( item ) ¶

参数：	item – `PySide.QtGui.QTreeWidgetItem`
返回类型：	`PySide.QtCore.bool`

PySide.QtGui.QTreeWidgetItemIterator. __iadd__ ( n ) ¶

参数：	n – `PySide.QtCore.int`
返回类型：	`PySide.QtGui.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 0. Returns the resulting iterator.

PySide.QtGui.QTreeWidgetItemIterator. __isub__ ( n ) ¶

参数：	n – `PySide.QtCore.int`
返回类型：	`PySide.QtGui.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 0. Returns the resulting iterator.

PySide.QtGui.QTreeWidgetItemIterator. value ( ) ¶

返回类型：	`PySide.QtGui.QTreeWidgetItem`
