wxpython + CollapsiblePane 不起作用

Question

我今天了解了可折叠窗格。但我无法让它工作。我得到的错误是：

"TypeError: in method 'new_CollapsiblePane', expected argument 1 of type 'wxWindow *'"

我尝试将可折叠过滤器作为 "def"，作为 class 并包含在 class 主体中。现在我没主意了。

这是我最近的代码：

class Main(wx.Panel):
    def __init__(self, parent=None, id=-1, notify_channel=None, **kwargs):
        wx.Panel.__init__(self, parent, id)
        "some other stuff"
       self.rightsizer.AddStretchSpacer(1)
       self.rightsizer.Add(self.listsizer, 80, wx.EXPAND)
       self.rightsizer.AddStretchSpacer(1)

       self.sizer.AddStretchSpacer(1)
       self.sizer.Add(CollapsibleFilter(self, label="Filter:"), 0, wx.EXPAND)
       self.sizer.AddStretchSpacer(1)
       self.sizer.Add(self.rightsizer, 50, wx.EXPAND)
       self.sizer.AddStretchSpacer(2)

       self.SetSizer(self.sizer)
       self.sizer.Fit(self)

class CollapsibleFilter(wx.CollapsiblePane):

    def __init__(self, notify_channel, **kwargs):
      wx.CollapsiblePane.__init__(self,wx.ID_ANY, **kwargs)
      self.notify_channel = notify_channel

      self.CollapsibleFilter=self.GetPane()


      self.filter1 = FilterBox(self.CollapsibleFilter, notify_channel=self.notify_channel)
      self.filter2 = FilterBox(self.CollapsibleFilter, notify_channel=self.notify_channel)
      self.filter3 = FilterBox(self.CollapsibleFilter, notify_channel=self.notify_channel)

      self.filter1.set_dropdown_items(browser_options.filterlist)
      self.filter1.set_dropdown_default(browser_options.default_1)
      self.filter2.set_dropdown_items(browser_options.filterlist)
      self.filter2.set_dropdown_default(browser_options.default_2)
      self.filter3.set_dropdown_items(browser_options.filterlist)
      self.filter3.set_dropdown_default(browser_options.default_3)

      #layout
      self.filtersizer = wx.BoxSizer(wx.VERTICAL)

      self.filtersizer.AddStretchSpacer(1)
      self.filtersizer.Add(self.filter1, 60, wx.EXPAND)
      self.filtersizer.AddStretchSpacer(1)
      self.filtersizer.Add(self.filter2, 60, wx.EXPAND)
      self.filtersizer.AddStretchSpacer(1)
      self.filtersizer.Add(self.filter3, 60, wx.EXPAND)
      self.filtersizer.AddStretchSpacer(1)

希望有人能帮助我！发送

就像任何小部件一样 class 它需要在构造时接收对父小部件的引用。在你的 CollapsibleFilter class 中，当它调用超级 class __init__ 时你没有传递父级，所以这就是它失败的原因。试试这个：

class CollapsibleFilter(wx.CollapsiblePane):
    def __init__(self, parent, notify_channel, **kwargs):
      wx.CollapsiblePane.__init__(self, parent, wx.ID_ANY, **kwargs)
      ...
