Detailed Description

The PySide.QtGui.QTreeWidgetItemIterator class provides a way to iterate over the items in a PySide.QtGui.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.

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 PySide.QtGui.QTreeWidgetItemIterator .

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

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

class PySide.QtGui.QTreeWidgetItemIterator(it)

Parameters:

• flags – PySide.QtGui.QTreeWidgetItemIterator.IteratorFlags
• item – PySide.QtGui.QTreeWidgetItem
• widget – PySide.QtGui.QTreeWidget
• it – PySide.QtGui.QTreeWidgetItemIterator

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

PySide.QtGui.QTreeWidgetItemIterator.IteratorFlag

These flags can be passed to a PySide.QtGui.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.

PySide.QtGui.QTreeWidgetItemIterator.__iter__()

Return type:PyObject

PySide.QtGui.QTreeWidgetItemIterator.__next__()

Return type:PyObject

PySide.QtGui.QTreeWidgetItemIterator.matchesFlags(item)

Parameters:item – PySide.QtGui.QTreeWidgetItem Return type:PySide.QtCore.bool

PySide.QtGui.QTreeWidgetItemIterator.__iadd__(n)

Parameters:n – PySide.QtCore.int Return type: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)

Parameters:n – PySide.QtCore.int Return type: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()

Return type:PySide.QtGui.QTreeWidgetItem
