A newbie to Tkinter here. . . . . .
I'm trying to set the focus on an Entry textbox with
focus_set. I am using the grid manager. I created the same
interface before using the pack() method and the focus_set
worked, but now it says
"AttributeError: 'NoneType' object has no attribute 'focus_set'"
Below is the section of the code:
# CREATES THE GUI FOR DCN INPUT
def get_dcn():
master = Tk()
_dcn = StringVar()
label1 = Label(text="Enter DCN:",width=10).grid(row=0)
txtbox = Entry(relief=SUNKEN, width=20, takefocus=1,
textvariable=_dcn).grid(row=0, column=1)
txtbox.focus_set()
btnOK=
Button(text="OK",command=assign_dcn(_dcn)).grid(ro w=1, column=0)
btnCancel = Button(text="Cancel",
command=killer).grid(row=1, column=1)
master.mainloop()
return
Does anyone know where I went wrong?
Regards. . . .
