Hello,
What's the proper way to use QTreeWidget's itemAt() method? I'm
passing incrementing int values to it, yet it only returns the tree's
root item. eg:
for ii in range(self.treeRowCount):
item = self.theTree.itemAt(0, ii)
yields:
ii: 0
item: <PyQt4.QtGui.QTreeWidgetItem object at 0x59ed0>
text: rootItem
ii: 1
item: <PyQt4.QtGui.QTreeWidgetItem object at 0x59ed0>
text: rootItem
ii: 2
item: <PyQt4.QtGui.QTreeWidgetItem object at 0x59ed0>
text: rootItem
ii: 3
item: <PyQt4.QtGui.QTreeWidgetItem object at 0x59ed0>
text: rootItem
(See attached for the full, simple code example.)
Ultimately, I want to be able to identify a QTreeWidgetItem by the
results of its text() so that I can set the tree item's parent for
branch points. Note that I'm building simple, small trees from stored
data sets. Hence the convenience widget rather than the model-view.
Thanks in advance!
Scott
