Hi, Still struggling with my GUI exercise -
I have the following lines of code in a routine that is bound at <Key-Return> to an instance of Entry : self.disp.Amount_des = Label(self.disp, text = self.dis_string, fg = 'black', bg = 'yellow') self.disp.Amount_des.grid(row = self.rownum, column=0, sticky = 'nesw') self.disp.Amount = Label(self.disp, text = self.retstring, fg = 'black', bg = 'green') self.disp.Amount.grid(row = self.rownum, column=1, sticky = N+S+E+W) The second call to the grid method fails as follows: Exception in Tkinter callback Traceback (most recent call last): File "E:\PYTHON24\lib\lib-tk\Tkinter.py", line 1345, in __call__ return self.func(*args) File "C:\WINDOWS\DESKTOP\Entry1.py", line 243, in entryend self.disp.Amount.grid(row = self.rownum, column=1, sticky = N+S+E+W) TypeError: cannot concatenate 'str' and 'instance' objects If I change the N+S+E+W to the 'nsew' form, it works no problem... Weird - at other places in the program the form: sticky = N+S+E+W works without a problem. I found the 'nsew' form by trial and error... self.disp is a window different from the current one - it is used to display a record entry as it is built up field by field. - the code fragment above is what inserts the description of the entry and the entered data in a row in the window used for displaying, when the user hits the enter key. Is this a bug, or am I still doing something wrong? - Hendrik -- http://mail.python.org/mailman/listinfo/python-list
