wxPython中是否有类似于tk.IntVar（）的方法？

Question

我正在将旧的tkinter程序转换为wxPython。我使用tk的一件事是tk.IntVar（）等。 wx中有没有提供类似功能的东西？

具体而言，我希望能够定义模块级别的变量，如myvar = tk.StringVar()。然后，当这些变量被更新，都基于一个或多个用户界面元素的更新上新的变量值，就像将与发生什么：

self.score = tk.Entry(self, textvariable=myvar.get())

这里是你如何通常会安排您的应用程序....全局趋向是一个坏主意

class MyNestedPanel(wx.Panel): 
    def __init__(self,*a,**kw): 
     ... 
     self.user = wx.TextCtrl(self,-1) 
     def SetUser(self,username): 
     self.user.SetValue(username) 

class MyMainPanel(wx.Panel): 
     def __init__(self,*a,**kw): 
      ... 
      self.userpanel = MyNestedPanel(self,...) 
     def SetUsername(self,username): 
      self.userpanel.SetUser(username) 

class MainFrame(wx.Frame): 
     def __init__(self,*a,**kw): 
      ... 
      self.mainpanel = MyMainPanel(self,...) 
     def SetUsername(self,username): 
      self.mainpanel.SetUsername(username) 

a = wx.App() 
f = MainFrame(...) 
f.Show() 
a.MainLoop() 

虽然可以让辅助功能

def set_widget_value(widget,value): 
    if hasattr(widget,"SetWidgetValue"): 
     return widget.SetWidgetValue(value) 
    if isinstance(widget,wx.Choice): 
     return widget.SetStringSelection(value) 
    if hasattr(widget,"SetValue"): 
     return widget.SetValue(value) 
    if hasattr(widget,"SetLabel"): 
     return widget.SetLabel(value) 
    else: 
     raise Exception("Unknown Widget Type : %r"%widget) 

def get_widget_value(widget): 
    if hasattr(widget,"GetWidgetValue"): 
     return widget.GetWidgetValue() 
    if isinstance(widget,wx.Choice): 
     return widget.GetStringSelection() 
    if hasattr(widget,"GetValue"): 
     return widget.GetValue() 
    if hasattr(widget,"GetLabel"): 
     return widget.GetLabel() 
    else: 
     raise Exception("Unknown Widget Type : %r"%widget) 

class WidgetManager(wx.Panel): 
     def __init__(self,parent): 
     self._parent = parent 
     wx.Panel.__init__(self,parent,-1) 
     self.CreateWidgets() 
     def CreateWidgets(self): 
     #create all your widgets here 
     self.widgets = {} 
     def SetWidgetValue(self,value): 
     if isinstance(value,dict): 
      for k,v in value.items(): 
       set_widget_value(self.widgets.get(k),v) 
     else: 
      raise Exception("Expected a dictionary but got %r"%value) 
     def GetWidgetValue(self): 
      return dict([(k,get_widget_value(v))for k,v in self.widgets]) 

，然后用它们这样https://gist.github.com/joranbeasley/37becd81ff2285fcc933
