  G = entry.get()
  
  button = Button(frame,text="Get",command=self.data(self.G))

Hi X, dont know if this work buy there is .self.G in your code, so if you pass 'G' instead?

Code:

entry = Entry(frame,fg="blue")
  entry.pack()
  G = entry.get()
  
  button = Button(frame,text="Get",command=self.data(G))
  button.pack(side=LEFT)
 
 def data(self,g):
  print g

Mark.

Give this a go

, if not attach your prgram so we can test it

Code:

    entry = Entry(frame,fg="blue")
    entry.pack()
    self.G = entry.get()
  
    button = Button(frame,text="Get",command=self.data)
    button.pack(side=LEFT)

def data(self):
    print self.G

Ok this is what got.. i changed it around a bit.. trying to get it to work and still nothing

Code:

#!/usr/bin/env python


from Tkinter import *
def printData(self,text=""):
 print text
 
root  = Tk()
frame = Frame(root,relief=GROOVE,border=1,height=32, width=32)
frame.pack_propagate(0)
frame.master.title("My ****y Program")


v = StringVar()

Label(frame,textvariable=v,font=("helvetica",12)).pack()
v.set("New Text!")
v.get()

buttonvar = StringVar()
buttonvar.set("Green")

entry =  Entry(frame,fg="blue")
text  =  entry.get()
button = Button(frame,text="Print",command=v.set(v))
button.pack()
entry.pack()


root.mainloop()

yet i cant find a descent tutorial anyware on the net, or not even for socket program

this part
button = Button(frame,text="Print",command=v.set(v))
i tried
button = Button(frame,text="Print",command=printData(text))
nothing happends, even with self.text

Here you go! All working, i'm betting you where getting a blank string printed to the console window.. this is because the text box starts of blank so this is the value being saved to your variable..

I tried running your code but i ended up with a blank window

so i just wrote you an example from scatch! On another point you should use tabs instead if spaces when you indent your code, not only does it lead to slightly smaller programs but its easier to see where the blocks are

Code:

#!/usr/bin/env python

import Tkinter as tk

class window:
	
	def __init__(self, root):
		frame = tk.Frame(root)
		
		self.button = tk.Button(frame, text = 'Print this..', command = self.output)
		self.entry = tk.Entry()
		self.entry.pack()
		self.button.pack()	
	
		frame.pack()
		
	def output(self):
		print 'entry =>', self.entry.get() or 'Nothing'
		
if __name__ == '__main__':

	root = tk.Tk()
	window(root)
	root.mainloop()

Mark.

the problem was that you where saving the value of the entry box while it was empty (''), what you need to do is call entry.get() from within your button function so that it loads the new value each time you click the button
