Synopsis

Functions

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 + 1

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

class PySide6.QtWidgets.QTreeWidgetItemIterator(widget[, flags=QTreeWidgetItemIterator.All])

PySide6.QtWidgets.QTreeWidgetItemIterator(item[, flags=QTreeWidgetItemIterator.All])

PySide6.QtWidgets.QTreeWidgetItemIterator(it)

Parameters

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.

See also

IteratorFlag

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

PySide6.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.
