i put a check button in a Frame. The "side" of the frame is right. I specify my check button to be on anchor 'center' but it goes on the right. Do you know how to solve this? Thank you
from tkinter import *
fenetre= Tk()
cadreoptions=Frame(fenetre,width=100,height=70,borderwidth=2)
cadreoptions.pack(side=RIGHT)
statusnegatif=IntVar()
negatifbutton= Checkbutton(cadreoptions,text='Négatif',variable=statusnegatif)
negatifbutton.pack(padx=5,pady=2,anchor='center')
fenetre.mainloop()
