Create checkboxes with loop?

philipp

Hi,

this may be a basic Python-class question.

I´m trying to show a basic window with multiple checkboxes in it. Which works fine, when I add them manually with their own attribute (?). (Example: https://gist.github.com/axani/5764824 )

But when I try to create multiple checkboxes with a loop I get an Assertion Error, because self.w.checkbox = … is used repeatedly.

AssertionError: can't replace vanilla attribute

So how can I build self.w.checkbox1 = …, self.w.checkbox2 = …, etc. via a loop?

sorry, its indeed CheckBox

Boing!

My mistake was a typo: It´s CheckBox, not Checkbox … Ah, the joys of programming!

Thanks for your help! :-)

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()

frederik

a better way is to use setattr

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

Probably there's a better way of doing this, but at least, in the meantime, this works:
(sorry I don't know how to format code properly in the forum)

from vanilla import *
 
class checkboxWindow:
    
    def __init__(self):
        
        self.w = Window((400,400), 'SetOrganizer')
        
        for n in range(5):
            exec("self.w.checkBox%s = CheckBox((10, 10 + (25*n+1), -10, -10), 'Label', callback=self.checkBoxCallback, value=True)" % n)
        
        self.w.open()
    
    def checkBoxCallback(self, sender):
        print sender.get(), sender.getTitle()
 
checkboxWindow()
