# A ScrolledText widget feels like a text widget but also has a# vertical scroll bar on its right.  (Later, options may be added to# add a horizontal bar as well, to make the bars disappear# automatically when not needed, to move them to the other side of the# window, etc.)## Configuration options are passed to the Text widget.# A Frame widget is inserted between the master and the text, to hold# the Scrollbar widget.# Most methods calls are inherited from the Text widget; Pack methods# are redirected to the Frame widget however. from Tkinter import *from Tkinter import _cnfmerge class ScrolledText(Text):    def __init__(self, master=None, cnf=None, **kw):        if cnf is None:            cnf = {}        if kw:            cnf = _cnfmerge((cnf, kw))        fcnf = {}        for k in cnf.keys():            if type(k) == ClassType or k == 'name':                fcnf[k] = cnf[k]                del cnf[k]        self.frame = Frame(master, **fcnf)        self.vbar = Scrollbar(self.frame, name='vbar')        self.vbar.pack(side=RIGHT, fill=Y)        cnf['name'] = 'text'        Text.__init__(self, self.frame, **cnf)        self.pack(side=LEFT, fill=BOTH, expand=1)        self['yscrollcommand'] = self.vbar.set        self.vbar['command'] = self.yview         # Copy geometry methods of self.frame -- hack!        methods = Pack.__dict__.keys()        methods = methods + Grid.__dict__.keys()        methods = methods + Place.__dict__.keys()         for m in methods:            if m[0] != '_' and m != 'config' and m != 'configure':                setattr(self, m, getattr(self.frame, m))
