[Tutor] tkinter, create widgets during runtime?

[Karim]

I never did that but this is python!
You can create anything you want at runtime!
Make a factory method in you gui class which inherit from Frame or 
whatever container code below is testing:

 >>> from Tkinter import *
 >>> class gui(Frame):
...      def __init__(self, master=None):
...          Frame.__init__(self, master)
...          self.pack()
...      def createLabels(self):
...          labels = []
...          for  i in range(4):
...               labelName = "myLabel_{0}".format(i)
...               labels.append(Label(master=self, text="this is label " 
+ labelName))
...          for label in labels:
...              label.pack()
...
 >>> a=gui()
 >>> a.createLabels()


self is the instance of your inherited Frame or else container.
