Question

I want to call multiple modules using for loop in paintEvent(), like

 def fun1(self,paint,a,b):
     do something ...
 def fun2(self,paint,a,b):
     do something ...
 def fun3(self,paint,a,b):
     do something .... 

 def paintEvent(self,event=None):
     for i in range (1,3):
        self.fun[i](self,paint,a,b)

basically my fun1, fun2 and fun3 are drawing some widgets and are almost same. Please help me how to call these functions using for loop.

Answer 1

You could do something like:

def fun1(self,paint,a,b):
    do something ...
def fun2(self,paint,a,b):
    do something ...
def fun3(self,paint,a,b):
    do something .... 

self.fun = [self.fun1,self.fun2,self.fun3]

def paintEvent(self,event=None):
    for i in range (1,3):
       self.fun[i](self,paint,a,b)

If fun1, fun2, and fun3 are almost the same thing as you have said, you should consider combining them into one function that you can call with an additional argument.
