Detailed Description¶
Warning
This section contains snippets that were automatically translated from C++ to Python and may contain errors.
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 ofQTreeWidgetItemIterator
.See also

- class IteratorFlag¶
(inherits
enum.Flag
) These flags can be passed to aQTreeWidgetItemIterator
constructor (OR-ed together if more than one is used), so that the iterator will only iterate over items that match the given flags.Constant

- __init__(it)¶
- Parameters:
Constructs an iterator for the same
QTreeWidget
asit
. The current iterator item is set to point on the current item ofit
.- __init__(widget[, flags=QTreeWidgetItemIterator.IteratorFlag.All])
- Parameters:
widget –
QTreeWidget
flags – Combination of
IteratorFlag
Constructs an iterator for the given
widget
that uses the specifiedflags
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.See also
- __init__(item[, flags=QTreeWidgetItemIterator.IteratorFlag.All])
- Parameters:
item –
QTreeWidgetItem
flags – Combination of
IteratorFlag
Constructs an iterator for the given
item
that uses the specifiedflags
to determine which items are found during iteration. The iterator is set to point toitem
, or the next matching item ifitem
doesn’t match the flags.See also
- __iter__()¶
- Return type:
object
- __next__()¶
- Return type:
object
- __iadd__(n)¶
- Parameters:
n – int
- Return type:
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
. Returns the resulting iterator.- __isub__(n)¶
- Parameters:
n – int
- Return type:
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
. Returns the resulting iterator.- value()¶
- Return type:
