WPROWADZENIE

Grid dzieli okno lub Frame na wiersze i kolumny. Lokalizację widżetu określamy przez wywołanie .grid() i przekazanie indeksów wiersza i kolumny do argumentów 'row' i 'column' (row=i, column=j). Indeksy dla wierszy i kolumn zaczynają się od zera.

Opcja 'sticky' dla grid opisuje jak widżet ma się ułożyć względem komórki siatki.

columnspan=2   # widget ma zająć dwie kolumny na siatce
rowspan=2   # widget ma zająć dwia wiersze na siatce

sticky=tk.N   # "n" or "N"
sticky=tk.E   # "e" or "E"
sticky=tk.S   # "s" or "S"
sticky=tk.W   # "w" or "W"
sticky=tk.NE   # "ne" or (tk.N, tk.E)
sticky=tk.NW   # "nw" or (tk.N, tk.W)
sticky=tk.SE   # "se" or (tk.S, tk.E)
sticky=tk.SW   # "sw" or (tk.S, tk.W)

sticky=tk.EW   # "ew" or (tk.E, tk.W)
sticky=tk.NS   # "ns" or (tk.N, tk.S)
sticky=tk.NSEW   # "nsew" or (tk.N, tk.S, tk.E, tk.W)
