我尝试了wxpython和PyQt5，但最终都停留在同一点。

我想使用在主窗口（原型）上按下两个按钮之一时创建的列表，将其放入我在第二帧上创建的组合框中。

但是，我总是得到AttributeError：类型对象'Prototype'没有属性'my_list'。

按下一个按钮并在第二帧SecondFrame中使用列表时，如何访问在主窗口原型中创建的“ my_list”？

Answer 1

.my_list是实例属性，而不是类属性。您必须将列表传递给SecondFrame类构造函数：

class SecondFrame(wx.Frame):
    def __init__(self, the_list):
        wx.Frame.__init__(self, None, title="Select Player", size=(800,600)) 
        self.my_list = the_list
        # ...


    def UI(self):
        # ...
        self.combo_box_1 = wx.ComboBox(self, wx.ID_ANY, choices=self.my_list, style=wx.CB_DROPDOWN | wx.CB_SORT)


class Prototype(wx.Frame):
    # ....
    def OnButton1(self, event):
      df = pd.read_pickle('C:/Users/XXX/Desktop/Project-Tennis/ATP_Rankings.pickle')
      self.my_list = df["Name"].tolist()
      frame = SecondFrame(self.my_list)
      frame.Show()

尝试从wxpython中的另一个类访问列表时遇到AttributeError
