QTreeWidget multiple selected items

[Arjun Thekkummadathil]

Hi

   Am writing a tool which has a QTreeWidget and i need to get the selected items from the widget am only able to get one selection.

How do i get multiple selected items

What are you using now to get the selected items that isn't giving you the full selection? Is it QTreeWidget.selectedItems()?

What is your QTreeWidget set to for its SelectionBehavior and SelectionMode? Does it already allow multi-row selection but is not returning multiple rows?

I figured it out i was using QTreeWidget.selectedItems() but then i was expecting it to return multiple objects, it returns one object which is ideally a list

I'm not sure I follow. It should always be a list, with one or more items in it. So it technically always returns multiple items (0+)

yeah that's what even i thought but then it returns me a object and i can loop through that, that object is not of a type list its some kind of Qt object but luckily i can loop through that

for i in object:

    print i.text(columnNumber)

that gives me the values

Are you using an old version of PyQt maybe? Because I am testing PyQt 4.8.6 in Maya 2013, using the default sip API v1, and QTreeWidget.selectedItems() returns a plain list of QTreeWidgetItems:

from PyQt4 import QtCore, QtGui

tree = QtGui.QTreeWidget()
tree.setSelectionMode(t.ExtendedSelection)

for i in xrange(5):
    item = QtGui.QTreeWidgetItem(["test"])
    tree.addTopLevelItem(item)

tree.show()

# Selected 4 things in the tree
result = tree.selectedItems()
print type(result), len(result)
# <type 'list'> 4

​

It returns exactly what the docs say: A list of QTreeWidgetItems

I actually use PySide

PySide also returns a list in the versions I am testing. In your version is it actually returning a QList? I wasn't aware that those were actually exposed to python bindings. Everything I have tried returns a python list. I will have to check my version of PySide in Maya 2014 when I get back to work.
