here i have a list containing n string values
str = ['var1','var2','var3',...]
variable = StringVar(str[0])
variable.set('hello world')
I want to convert the all string values in the list into String Var()
This program shows error like str object has no object _root
I tried in may ways but I can't
thanks in advance for answers...!!
You need to create root window before defining strVars. Try like this:
import tkinter
root=tkinter.Tk()
strs = ['var1','var2','var3']
strvars = []
for s in strs:
strvar = tkinter.StringVar(value=s)
strvars.append(strvar)
print(strvars)
root.mainloop()
import tkinter
root=tkinter.Tk()
variable = StringVar(root)
for st_r in ['var1','var2','var3',...]:
variable.set(st_r)
root.mainloop()
Update:
import tkinter as tk
root=tk.Tk()
variable = tk.StringVar(root)
tk.Label(root, textvariable=variable).grid(row=0, column=3)
for st_r in ['var1','var2','var3',...]:
variable.set(st_r)
root.update()
input()
root.mainloop()
variable?
variable.set(["var1", ...][-1]).
variable = StringVar(value=str[0]).
