Re: [Tutor] Misunderstanding the Entry Widget

[Wayne Watson]

Title: Signature.html

I had commented out #        entry = Entry(master, width=10, textvariable=self.slowdownVar).grid(row=4, column=1), which had worked fine previously to my changes. I added your two statements after remarking entry = Entry(master, width=10).grid(row=4, column=1) IDLE & the Command prompt window produced, which was really what I was showing in the image that I removed: Exception in Tkinter callback Traceback (most recent call last):   File "C:\Python25\Lib\lib-tk\Tkinter.py", line 1403, in __call__     return self.func(*args)   File "C:\Sandia_Meteors\Sentinel_Development\Development_Sentuser-Utilities\sentuser\sentuserNC25-Dev5.py", line 579, in OperationalSettings     dialog = OperationalSettingsDialog( self.master, set_loc_dict )   File "C:\Sandia_Meteors\Sentinel_Development\Development_Sentuser-Utilities\sentuser\sentuserNC25-Dev5.py", line 84, in __init__     tkSimpleDialog.Dialog.__init__(self, parent)   File "C:\Python25\lib\lib-tk\tkSimpleDialog.py", line 64, in __init__     self.initial_focus = self.body(body)   File "C:\Sandia_Meteors\Sentinel_Development\Development_Sentuser-Utilities\sentuser\sentuserNC25-Dev5.py", line 115, in body     entry.insert(0,self.slowdown) AttributeError: OperationalSettingsDialog instance has no attribute 'slowdown' Kent Johnson wrote: On Mon, Mar 9, 2009 at 8:30 AM, Wayne Watson <sierra_mtnv...@sbcglobal.net> wrote:         entry = Entry(master, width=10).grid(row=4, column=1) You have to write this as entry = Entry(master, width=10) entry.grid(row=4, column=1) The grid() method returns None, that is why entry is None.
