[SOLVED] Python with Tkinter, problems with grid placement
Dear all
I am trying to make a small wrapper program for textbased program and
it is going well but I have one problem. The placement of the widgets with grid is acting so strange. Eventhough I tried to place the button in a grid the ouput is totally different from what I designed.
I would have expected that the following made theese 3 buttons sit next to each other on a row
but as can be seen in this picture they don't?Code:self.writetofileLabel.grid(row=0, column=0, sticky=W) self.outputfileEntry.grid(row=0, column=1) self.writetofileButton.grid(row=0, column=2)
Kind regardsCode:#!/usr/bin/python """\ Graphical interface for geocol12 Thomas R. N.
