文本窗口小部件中的Tkinter滚动条(Scrollbar in Tkinter inside Text widget)

 我在Tkinter的Text小部件里面的Scrollbar中设置了问题。 我知道，最好使用网格来定位窗口小部件，但我想将窗口小部件设置为绝对位置（x，y - GUI图片上的红点），并指定高度和宽度。 
 
 我的代码： 
 
from Tkinter import *
from ttk import *

class NotebookDemo(Frame):

    def __init__(self):      
        Frame.__init__(self)       
        self.pack(expand=1, fill=BOTH)
        self.master.title('Sample')
        self.master.geometry("650x550+100+50")
        self._initUI()

    def _initUI(self):
        self._createPanel()

    def _createPanel(self):

        # create frame inside top level frame
        panel = Frame(self)    
        panel.pack(side=TOP, fill=BOTH, expand=1)

        # create the notebook
        nb = Notebook(panel)
        nb.pack(fill=BOTH, expand=1, padx=2, pady=3)        
        self._FirstTab(nb)


    def _FirstTab(self, nb):

        # frame to hold content
        frame = Frame(nb)

        #textbox
        txtOutput = Text(frame, wrap = NONE, height = 17, width = 70)
        txtOutput.place(x=10, y=75)

        #button
        btnStart = Button(frame, text = 'Start', underline=0)
        btnStart.place(x=220, y=380)

        #scrollbar
        #vscroll = Scrollbar(frame, orient=VERTICAL, command=txtOutput.yview)
        #txtOutput['yscroll'] = vscroll.set
        #vscroll.pack(side=RIGHT, fill=Y)
        #txtOutput.pack(fill=BOTH, expand=Y)

        #add to notebook (underline = index for short-cut character)
        nb.add(frame, text='TAB 1', underline=0, padding=2)

if __name__ == '__main__':
    app = NotebookDemo()
    app.mainloop()
 
  
 
 如果我取消注释这部分代码（设置Scrollbar）： 
 
vscroll = Scrollbar(frame, orient=VERTICAL, command=txtOutput.yview)
txtOutput['yscroll'] = vscroll.set
vscroll.pack(side=RIGHT, fill=Y)
 
 我的滚动条位于所有窗口内，不在文本框内： 
 
  
 
 但是我当然希望在文本框小部件（黑色边框）内部使用滚动条。 如果我使用pack函数到文本框： 
 
txtOutput.pack(fill=BOTH, expand=Y)
 
 文本小部件填写整个窗口...： 
 
  
 
 我真的不知道如何解决这个问题。 任何帮助将不胜感激。 谢谢！ 
 
 编辑： 
 
 当然我也可以使用滚动条的方法，但我不能改变它们的长度，因为它没有属性长度。 
 
vscroll.place(x=573, y=75)
 
  

I have problem with set in Scrollbar inside Text widget in Tkinter. I know, that it's preferable to use grid to locate widgets but I want to set my widget in absolute location (x,y - red dot on GUI picture) with specified height and width.
 
My code:
 
from Tkinter import *
from ttk import *

class NotebookDemo(Frame):

    def __init__(self):      
        Frame.__init__(self)       
        self.pack(expand=1, fill=BOTH)
        self.master.title('Sample')
        self.master.geometry("650x550+100+50")
        self._initUI()

    def _initUI(self):
        self._createPanel()

    def _createPanel(self):

        # create frame inside top level frame
        panel = Frame(self)    
        panel.pack(side=TOP, fill=BOTH, expand=1)

        # create the notebook
        nb = Notebook(panel)
        nb.pack(fill=BOTH, expand=1, padx=2, pady=3)        
        self._FirstTab(nb)


    def _FirstTab(self, nb):

        # frame to hold content
        frame = Frame(nb)

        #textbox
        txtOutput = Text(frame, wrap = NONE, height = 17, width = 70)
        txtOutput.place(x=10, y=75)

        #button
        btnStart = Button(frame, text = 'Start', underline=0)
        btnStart.place(x=220, y=380)

        #scrollbar
        #vscroll = Scrollbar(frame, orient=VERTICAL, command=txtOutput.yview)
        #txtOutput['yscroll'] = vscroll.set
        #vscroll.pack(side=RIGHT, fill=Y)
        #txtOutput.pack(fill=BOTH, expand=Y)

        #add to notebook (underline = index for short-cut character)
        nb.add(frame, text='TAB 1', underline=0, padding=2)

if __name__ == '__main__':
    app = NotebookDemo()
    app.mainloop()
 
 
If I uncomment this part of code (set Scrollbar):
 
vscroll = Scrollbar(frame, orient=VERTICAL, command=txtOutput.yview)
txtOutput['yscroll'] = vscroll.set
vscroll.pack(side=RIGHT, fill=Y)
 
My Scrollbar is located inside all window, not inside Text box:
 
 
But of course I want to have the Scrollbar inside the Text box widget (black border). If I use pack function to textbox:
 
txtOutput.pack(fill=BOTH, expand=Y)
 
text widget fill in the whole window...:
 
 
I really don't know how fix this problem. Any help will be appreciated. Thank you!
 
EDIT:
 
Of course I can use place method with Scrollbar too, but I can't change length of them, because it hasn't attribute length.
 
vscroll.place(x=573, y=75)
