Question

这是我的示例代码，我想在窗口小部件中显示我的所有产品，因此我在for循环中将其作为字典使用，但是我没有在字典中获取所有产品，最后一个产品覆盖了前一个产品。请问任何一个可以帮助我做错了的地方。谢谢您。下面是我的代码：

products_list = {"Givers":{"price": 140,"Quantity":100,"Discount":0,"Total_price":14000,"Paid_amount":14000},"New_Member":{"price": 1200,"Quantity":10,"Discount":0,"Total_price":12000,"Paid_amount":12000},"YearMembers_Ribbons":{"price": 110,"Quantity":0,"Discount":0,"Total_price":1100,"Paid_amount":1100}}
for key,value in products_list.items():
    self.widget_orders_info = QtGui.QWidget()
    self.widget_orders_info.setWindowFlags(QtCore.Qt.FramelessWindowHint)
    self.widget_orders_info.setStyleSheet("QWidget {background-color: blue;color: white;}")
    self.order_info_vbox = QtGui.QVBoxLayout(self.widget_orders_info)
    self.title_hbox = QtGui.QHBoxLayout()
    self.orderdetail_label = QtGui.QLabel("Order_Details(22HRS)",alignment =QtCore.Qt.AlignCenter,objectName="small")
    self.close_pushbtn = QtGui.QPushButton("Close")
    self.title_hbox.addWidget(self.orderdetail_label)
    self.title_hbox.addStretch()
    self.title_hbox.addWidget(self.close_pushbtn)
    self.close_pushbtn.clicked.connect(self.widget_orders_info.close)
    self.order_info_vbox.addLayout(self.title_hbox)
    self.line = QtGui.QFrame(frameShape=QtGui.QFrame.HLine)
    self.order_info_vbox.addWidget(self.line)
    self.order_hbox = QtGui.QHBoxLayout()
    keys = value.keys()
    values = value.values()
    self.line1 = QtGui.QFrame(frameShape=QtGui.QFrame.VLine)
    self.order_hbox.addWidget(self.line1)
    self.items_Vboxlay = QtGui.QVBoxLayout()
    self.vbox2 = QtGui.QVBoxLayout()
    self.item_label = QtGui.QLabel(str(key), objectName="small")
    self.vbox2.addWidget(self.item_label)
    self.hbox1 = QtGui.QHBoxLayout()
    self.price = QtGui.QLabel(keys[1]+": " +str(values[1]))
    self.qnty =QtGui.QLabel(keys[4]+": "+str(values[4]))
    self.discount = QtGui.QLabel(keys[0]+ ": " +u'\u20B9 '+ str(values[0]))
    self.totalprice =QtGui.QLabel(keys[2]+ ": "+u'\u20B9 '+ str(values[2]))
    self.paid = QtGui.QLabel(keys[3] + ": "+u'\u20B9 '+ str(values[3]))
    self.hbox1.addWidget(self.price)
    self.hbox1.addWidget(self.qnty)
    self.hbox1.addWidget(self.discount)
    self.hbox1.addWidget(self.totalprice)
    self.hbox1.addWidget(self.paid)
    self.line4 = QtGui.QFrame();self.line4.setFrameShape(QtGui.QFrame.HLine)
    self.vbox2.addLayout(self.hbox1)
    self.vbox2.addLayout(self.h2box)
    self.vbox2.addWidget(self.line1)
self.items_Vboxlay.addLayout(self.vbox2)
self.order_hbox.addLayout(self.items_Vboxlay)
self.order_info_vbox.addLayout(self.order_hbox)
self.add_hbox = QtGui.QHBoxLayout()
self.print_btn = QtGui.QPushButton("Print")
self.print_btn.clicked.connect(partial(self.print_function,type))
self.add_hbox.setAlignment(QtCore.Qt.AlignCenter)
self.add_hbox.addWidget(self.print_btn)
self.order_info_vbox.addLayout(self.add_hbox)
self.widget_orders_info.show()
self.widget_orders_info.resize(500,300)

抱歉，我有Python-3和PyQt5。我认为我的榜样应该会对您有所帮助。
