Wx.Gauge控件可以在確定的以及不確定模式中使用。當(dāng)完成任何操作所需的時(shí)間可以被相當(dāng)精確地確定，測量儀進(jìn)度條顯示已完成任務(wù)的百分比。然而如果在不確定模式，它只是表示該過程正在進(jìn)行中。

wx.Gauge(parent, id, range, pos, size, style)

此類一些的重要的方法列于下表中 −

實(shí)例

self.gauge = wx.Gauge(pnl, range = 20, size = (250, 25), style = wx.GA_HORIZONTAL)

self.btn1 = wx.Button(pnl, label = "Start") 
self.Bind(wx.EVT_BUTTON, self.OnStart, self.btn1)

def OnStart(self, e): 
   while True: 
      time.sleep(1); 
      self.count = self.count + 1 
      self.gauge.SetValue(self.count) 
		
      if self.count >= 20: 
         print "end" 
         return
