When a form resizes, how do I resize the columns so they will occupy all available 
space? E.g. if stringgrid.width=100 and I have 4 columns, how do I adjust the 
columns width?

Answer:

1   procedure TForm1.FormResize(Sender: TObject);
2   var
3     c: integer;
4     colWidth: integer;
5     lineWidths: integer;
6     delta: integer;
7   begin
8     Grid.Width := ClientWidth - 24; {or whatever}
9     lineWidths := Grid.GridLineWidth * (Grid.ColCount - 1);
10    colWidth := (Grid.ClientWidth div Grid.ColCount) - Grid.GridLineWidth;
11    delta := (Grid.ClientWidth - (colWidth * Grid.ColCount)) - lineWidths;
12    for c := 0 to Grid.ColCount - 1 do
13    begin
14      Grid.ColWidths[c] := colWidth;
15      if c = Grid.ColCount - 1 then
16        Grid.ColWidths[c] := Grid.ColWidths[c] + delta;
17    end;
18  end;
