QTreeWidget Signal itemDoubleClicked Returns QModelIndex?

[MiBr]

I have a QTreeWidget with QTreeWidgetItems or in my case CustomTreeItems and when I use the signal itemDoubleClicked instead of returning a QTreeWidgetItem it returns a QModelIndex. Is this normal behavior?

CODE:

def on_double_click_tree(self, currItem):
        print(currItem)
        print("row: ",currItem.row())
        print("data: ",currItem.data())
        print("parent: ",currItem.parent())

self.modemTree.doubleClicked.connect(self.on_double_click_tree)

def on_select_tree_item(self, currItem):
          print(currItem)

self.modemTree.itemClicked.connect(self.on_select_tree_item)

A single click returns a CustomTreeItem (QTreeWidgetItem) which is expected, however a double click returns the QModelIndex which is not expected.

Yes, but you can access the Data by using the method data() from the QModelIndex
