Python Tkinter滚动条问题

我正在接受一个奇怪的行为和 Tkinter scrollbar 的例外 . 我的GUI基本上使用了与滚动条相关/引用的Tkinter Text Widget .

self.textFrame = Tkinter.LabelFrame (self.mainFrame,padx=0,pady=0,width=200,height=100)
    self.textFrame.grid(row=5, column =1, sticky = "NW", padx = 5, pady = 10)
    self.consLable = Tkinter.Label (self.textFrame,text = "Log-Console:",font ="Verdana 8 bold")
    self.consLable.grid (row =6,column =1, sticky = "NW", padx = 5, pady = 1)
    self.consText= Tkinter.Text(self.textFrame, wrap = "word")
    self.consText.grid(row =7,column =1, rowspan =4)
    self.consText.tag_configure("stderr", foreground="#b22222")
    self.scrollText= Tkinter.Scrollbar(self.textFrame,command = self.consText.yview)
    self.scrollText.grid(row =7,column =2,rowspan =4,sticky='NSEW')
    self.consText.config(yscrollcommand = self.scrollText.set)

    # Referencing output location of the console "print or sys.stderr" methods
    sys.stdout = gemeindesteckbrief__SupportTools__.TextRedirector(self.consText, "stdout")
    sys.stderr=  gemeindesteckbrief__SupportTools__.TextRedirector(self.consText, "stderr")

在Text Widget本身中，使用 sys.stdout 和 sys.stderr 插入python控制台条目 . 要插入文本，使用支持类覆盖 .sys.stderr.write 或 print 方法并将文本写入Tkinter文本小部件 .

class TextRedirector(object):
def __init__(self,widget, tag):
    self.targetwidget = widget
    self.targettag = tag

#@Override the sys.stdout & sys.stderr methods to write to the text widget instead of the python console
def write(self, str):
    self.targetwidget.configure(state="normal")
    self.targetwidget.insert("end", str, (self.targettag,))
    self.targetwidget.configure(state="disabled")

将文本插入Text Widget按预期工作，同时单击Widget并使用鼠标滚轮滚动工作正常，同时使用滚动条工作的向上和向下按钮 . 所有麻烦都开始使用吧，并试图上下滑动 . 效果是 TclError: expected floating-point number but got "0,0028"
