[Tutor] newbie TK question

[Richard Chamberlain]

Hi Joseph,

from Tkinter import *
root=Tk()
myStringVar=StringVar()
entry=Entry(root,textvariable=myStringVar,width=30)
def entryReturn(event):
    str=myStringVar.get()
    print str
    myStringVar.set('')
entry.bind('<Return>',entryReturn)
entry.pack()
root.mainloop()

Entry (and a few other widgets) have a textvariable option to which you give
an instance of StringVar. After that your instance (in the case above
myStringVar) has a set and a get method. So I bind a <Return> event to the
entryReturn method and then use .get() to get the contents of the entry.
