如何获取调用contextMenu（）的父小部件

Question

我有一个树梢，我在上面调用customContextMenu。 但我无法获取调用它的widgetItem

我试着看文件，但什么也没找到

树梢：

self.treeWidget = QtWidgets.QTreeWidget(self.centralwidget)
self.treeWidget.headerItem().setText(0, "Database Explorer")
self.treeWidget.setContextMenuPolicy(Qt.CustomContextMenu)
self.treeWidget.customContextMenuRequested.connect(self.openMenu)

def openMenu(self,position):
        menu = QtWidgets.QMenu()
        deleteAction = menu.addAction("Delete")
        showAction = menu.addAction("Show")
        action = menu.exec_(self.treeWidget.mapToGlobal(position))
        if action == deleteAction:
            self.my_function(treeWidgetItemObject)

我想获取treeWidgetItem的对象，在我的函数（）中调用了contextMenu

如果要获取与按下的项相关联的QModelIndex或由QTreeWidgetItem返回的itemAt()，则必须使用indexAt()

def openMenu(self,position):
        menu = QtWidgets.QMenu()
        deleteAction = menu.addAction("Delete")
        showAction = menu.addAction("Show")
        pos = self.treeWidget.viewport().mapToGlobal(position)
        action = menu.exec_(pos)
        if action == deleteAction:
            ix = self.treeWidget.indexAt(position)
            if ix.isValid():
                print(ix.data())
                it = self.treeWidget.itemFromIndex(ix)
                texts = [it.text(c) for c in range(it.columnCount())]
                print(texts)
