Hi Jack,

thanks for your detailed answer! I will try to integrate your recommendation and report back next week. :-)

joanca, frederik, thanks for your fast answers!

joancas suggestion works. Though I read often that

exec()

might be dangerous to use. Unfortunately I get an NameError with frederiks variant:

NameError: global name 'Checkbox' is not defined

This is my current code:

from vanilla import *

class setOrganizer():

    def __init__(self):
        self.w = Window((400,400), 'checkBoxWindow')
        
        for i in range(10):
            checkboxObject = Checkbox((10, 10, 10+30*i, 22), "label %s" % i)
            setattr(self.w, "checkBox_%s" % i, checkboxObject)

        self.w.open()
        
setOrganizer()
