QTreeWidgetItemIterator

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

Detailed Description

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

For example, the following code examples each item in a tree, checking the text in the first column against a user-specified search string:

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

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

IteratorFlags

Constructs an iterator for the given widget that uses the specified 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

Constructs an iterator for the given item that uses the specified 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

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

PySide2.QtWidgets.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.

PySide2.QtWidgets.QTreeWidgetItemIterator.__iter__()

Return type

PyObject

PySide2.QtWidgets.QTreeWidgetItemIterator.__next__()

Return type

PyObject

PySide2.QtWidgets.QTreeWidgetItemIterator.__iadd__(n)

Parameters

n – int

Return type

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.

PySide2.QtWidgets.QTreeWidgetItemIterator.__isub__(n)

Parameters

n – int

Return type

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.
