5. 以glade-3開啟calculator.glade

   1. table1 Rows: 5 -> 6
   2. insert ok button in table1 (0,5)
   3. rename ok button Label and Name to Sqrt
   4. set Sqrt button clicked Signals to on_Sqrt_clicked
   5. vim calculatorglade.py
   
   # coding: utf-8
   import sys
   import math # 匯入數學模組
   try:
   	import pygtk
   	pygtk.require('2.0')
   except:
   	pass
   .... omission ....
   
   class Calculator:
   .... omission ....
   			"on_Add_clicked" : self.displayAdd,
   			"on_Sqrt_clicked" : self.displaySqrt, # 定義sqrt按鈕接受函式
   .... omission ....
   		if operator == 'Sqrt':
   			self.firstOperand = self.wTree.get_widget("displayText").get_text()
   			result = math.sqrt(float(self.firstOperand))
   			self.wTree.get_widget("displayText").set_text(str(result))
   .... omission ....
   	
   	def displaySqrt(self,widget): #定義displaySqrt函式
   		self.compute("Sqrt")
   

6. 執行

   [dywang@deyu glade]$ python calculatorglade.py
