wxPython子類從類中獲取屬性

Question

我有一個wxpython程序，其中我按照教程子類化wx.Dialog。在對話框中，我創建一個面板和一個尺寸。

class StretchDialog(wx.Dialog): 

'''A generic image processing dialogue which handles data IO and user interface. 
This is extended for individual stretches to allow for the necessary parameters 
to be defined.''' 

def __init__(self, *args, **kwargs): 
    super(StretchDialog, self).__init__(*args, **kwargs) 

    self.InitUI() 
    self.SetSize((600,700)) 

def InitUI(self): 
    panel = wx.Panel(self) 
    sizer = wx.GridBagSizer(10,5) 

塊註釋說明什麼功能我想實現的，基本上是動態生成以此爲基礎更復雜的對話框。要做到這一點我已經試過：

class LinearStretchSubClass(StretchDialog): 
'''This class subclasses Stretch Dialog and extends it by adding 
    the necessary UI elements for a linear stretch''' 

def InitUI(self): 
    '''Inherits all of the UI items from StretchDialog.InitUI if called as a method''' 
    testtext = wx.StaticText(panel, label="This is a test") 
    sizer.Add(testtext, pos=(10,3)) 

我通過InitUI方法調用子類可以延長，但在父類InitUI不覆蓋UI生成。我無法做到的是將面板和大概的sizer屬性從父母傳遞給孩子。

我嘗試了許多變化的面板= StretchDialog.panel和麪板= StretchDialog.InitUI.panel到沒有結束。

是否有可能通過繼承父類來實現wxpython？如果是這樣，當我嘗試訪問面板時如何搞亂命名空間？

你在子類InitUI導致InitUI不要在StretchDialog

叫你可以做這樣的

class StretchDialog(wx.Dialog): 

    '''A generic image processing dialogue which handles data IO and user interface. 
     This is extended for individual stretches to allow for the necessary parameters 
     to be defined.''' 

    def __init__(self, *args, **kwargs): 
     super(StretchDialog, self).__init__(*args, **kwargs) 

     self.InitUI() 
     self.SetSize((600,700)) 

    def InitUI(self): 
     #save references for later access 
     self.panel = wx.Panel(self) 
     self.sizer = wx.GridBagSizer(10,5) 

然後在你的子類

class LinearStretchSubClass(StretchDialog): 
'''This class subclasses Stretch Dialog and extends it by adding 
the necessary UI elements for a linear stretch''' 

    def InitUI(self): 
    '''Inherits all of the UI items from StretchDialog.InitUI if called as a method''' 
     StretchDialog.InitUI(self) #call parent function 
     testtext = wx.StaticText(self.panel, label="This is a test") 
     self.sizer.Add(testtext, pos=(10,3))
