The QTreeWidgetItemIterator class provides a way to iterate over the items in a QTreeWidget instance.

The iterator will walk the items in a pre-order traversal order, thus visiting the parent node before it continues to the child nodes.

It is possible to filter out certain types of node by passing certain flags to the constructor of QTreeWidgetItemIterator.

Type Documentation

QTreeWidgetItemIterator.IteratorFlag

These flags can be passed to a QTreeWidgetItemIterator constructor (OR-ed together if more than one is used), so that the iterator will only iterate over items that match the given flags.

The IteratorFlags type is a typedef for QFlags<IteratorFlag>. It stores an OR combination of IteratorFlag values.

Method Documentation

QTreeWidgetItemIterator.__init__ (self, QTreeWidgetItemIterator it)

Constructs an iterator for the same QTreeWidget as it. The current iterator item is set to point on the current item of it.

QTreeWidgetItemIterator.__init__ (self, QTreeWidget widget, IteratorFlags flags = QTreeWidgetItemIterator.All)

Constructs an iterator for the QTreeWidget widget. The iterator is set to point to the first toplevel item (QTreeWidgetItem) of widget or the next matching item if the toplevel item doesn't match the flags.

See also QTreeWidgetItemIterator.IteratorFlag.

QTreeWidgetItemIterator.__init__ (self, QTreeWidgetItem item, IteratorFlags flags = QTreeWidgetItemIterator.All)

Constructs an iterator for the QTreeWidget that contains the item using the flags flags. The iterator is set to point to item or the next matching item if item doesn't match the flags.
