wxPython：計算器的用戶輸入顯示

Question

我是Python新手，這是我第一次嘗試使用wxPython構建我自己的Calculator應用程序。

import wx 

######################################################################## 
class PyCalc(wx.Frame): 
    """ 
    Python Calculator using wxPython 
    """ 

    #---------------------------------------------------------------------- 
    def __init__(self): 
     """Constructor"""   
     wx.Frame.__init__(self, None, wx.ID_ANY, 
          "Py Calculator", 
          size=(320,240) 
         ) 
     panel = wx.Panel(self) 

     button1 = wx.Button(panel, label="1") 
     button1.Bind(wx.EVT_BUTTON, lambda evt, name=button1.GetLabel(): self.onButton(evt, name)) 
     button2 = wx.Button(panel, label="2") 
     button2.Bind(wx.EVT_BUTTON, lambda evt, name=button2.GetLabel(): self.onButton(evt, name)) 
     button3 = wx.Button(panel, label="3") 
     button3.Bind(wx.EVT_BUTTON, lambda evt, name=button3.GetLabel(): self.onButton(evt, name)) 
     button4 = wx.Button(panel, label="4") 
     button4.Bind(wx.EVT_BUTTON, lambda evt, name=button4.GetLabel(): self.onButton(evt, name)) 
     button5 = wx.Button(panel, label="5") 
     button5.Bind(wx.EVT_BUTTON, lambda evt, name=button5.GetLabel(): self.onButton(evt, name)) 
     button6 = wx.Button(panel, label="6") 
     button6.Bind(wx.EVT_BUTTON, lambda evt, name=button6.GetLabel(): self.onButton(evt, name)) 
     button7 = wx.Button(panel, label="7") 
     button7.Bind(wx.EVT_BUTTON, lambda evt, name=button7.GetLabel(): self.onButton(evt, name)) 
     button8 = wx.Button(panel, label="8") 
     button8.Bind(wx.EVT_BUTTON, lambda evt, name=button8.GetLabel(): self.onButton(evt, name)) 
     button9 = wx.Button(panel, label="9") 
     button9.Bind(wx.EVT_BUTTON, lambda evt, name=button9.GetLabel(): self.onButton(evt, name)) 
     button10 = wx.Button(panel, label="10") 
     button10.Bind(wx.EVT_BUTTON, lambda evt, name=button10.GetLabel(): self.onButton(evt, name)) 

     sizer = wx.GridSizer(rows = 3, cols=3, hgap =5,vgap =5) 
     sizer.Add(button1) 
     sizer.Add(button2) 
     sizer.Add(button3) 
     sizer.Add(button4) 
     sizer.Add(button5) 
     sizer.Add(button6) 
     sizer.Add(button7) 
     sizer.Add(button8) 
     sizer.Add(button9) 
     sizer.Add(button10) 

     panel.SetSizer(sizer) 

    #---------------------------------------------------------------------- 
    def onButton(self, event, buttonLabel): 
     """""" 
     print "You pressed the %s button!" % buttonLabel 

# Run the program 
if __name__ == "__main__": 
    app = wx.PySimpleApp() 
    frame = PyCalc().Show() 
    app.MainLoop() 

我的問題是我應該用什麼來顯示計算器中的顯示框，顯示用戶鍵入的內容？ WxPython中有什麼？

wx.StaticText似乎適用於這種情況。

self.display = wx.StaticText(panel, label='0') 
sizer.Add(self.display) 

可以使用SetLabel方法或屬性Label更改文本：

self.display.SetLabel('calculated_value') 
# or 
self.display.Label = 'calculated_value'
