获取当前的QTreeWidget项

I presently have a QTreeWidget named 'treeWidget', and for the life of me, cannot figure out how to get the index value or the text of the selected treeWidget branch.

目前，我有一个名为“treeWidget”的QTreeWidget，在我的生命中，我无法找到如何获取所选treeWidget分支的索引值或文本。

self.treeWidget looks like:
User
-Inbox
-Sent
-Drafts
-Trash

自我。treeWidget看起来像:用户-收件箱-发送-草稿-垃圾

I need to know which branch is selected so I can display folders in the branch's corresponding file folder. I've been trying to understand the Qt documentation, but I'm totally stumped by the C++. And the PyQt docs don't have any examples. I've searched everywhere for three days trying to tinker and figure out the answer but keep coming up with errors.

我需要知道选择了哪个分支，以便在该分支的相应文件文件夹中显示文件夹。我一直在尝试理解Qt文档，但是我完全被c++所困扰。PyQt文档没有任何例子。我到处找了三天，试着修补一下，找出答案，但总是出错。

The closest I think I've come is something like this:

我觉得最接近的是这样的:

self.connect(self.treeWidget,SIGNAL("itemSelectionChanged()"), self.loadAllMessages)

def loadAllMessages(self, folder):
    item = self.treeWidget.currentItem()

Do I need to setSelectionMode first or something? All help is greatly appreciated!

我需要先选择setSelectionMode还是什么?非常感谢您的帮助!

Try This

试试这个

#remove the old way of connecting
#self.connect(self.treeWidget,SIGNAL("itemSelectionChanged()"), self.loadAllMessages)
self.treeWidget.itemSelectionChanged.connect(self.loadAllMessages)
def loadAllMessages(self, folder):
    getSelected = self.treeWidget.selectedItems()
    if getSelected:
        baseNode = getSelected[0]
        getChildNode = baseNode.text(0)
        print getChildNode
