[Tutor] tk entry focus

[Ron Weidner]

I've struggled... Now I'm asking...

What's wrong with this code?  Or more to the point,
how do you set the focus to an Entry widget?

Traceback (most recent call last):
  File "./run_dialogue.py", line 33, in ?
    app = Run_dialogue( root )
  File "./run_dialogue.py", line 23, in __init__
    self.cmd.focus()
AttributeError: 'NoneType' object has no attribute
'focus'


class Run_dialogue:
	def __init__( self, master ):
		img_path = path.dirname(sys.argv[0])
		img_path = path.abspath(img_path)
		#master.initial_focus.focus_set()
		master.geometry( "300x150+200+200")
		self.cmd_text = StringVar()
		self.frame = Frame( master )
		self.icon = PhotoImage( file=img_path +
"/target.gif" )
		self.lbl_icon = Label( self.frame, image=self.icon )
		self.lbl_icon.grid( row = 1, column = 0 )
		self.label = Label( self.frame, text="Command: "
).grid( row = 1, column = 1 )
		self.cmd   = Entry( self.frame,
textvariable=self.cmd_text ).grid( row = 1, column = 2
)
		self.btn   = Button( self.frame, text=" Run ",
command=self.btn_run_click )
		self.btn.grid( row = 2, column = 0, columnspan = 3,
sticky = "e")
		self.btn.bind("<Return>", self.btn_run_click) 
		self.frame.pack()
		self.cmd.focus()
