Hey
I've read http://wiki.lazarus.freepascal.org/Grids_Reference_Page#Sort
ing_Columns_or_Rows which is useful to learn how to sort a grid by a
column when the grid is clicked generally, but what I'm after is to
discover how to sort my grid in the same way that spreadhseets
do...i.e. if I have Column1, Column 2 and Column3 and I want to sort
the user to be able to sort by Column2 if the user clicks the grey
title area of Column2. Likewise for Column1 or 3.

Code: [Select]procedure TForm1.StringGrid1Click(Sender: TObject);
begin
  Stringgrid1.SortColRow(true, 1);  // This sorts by column 2 works
when I just click the grid,
  // but how can I sort by column 2 when, and only when, the user
clicks the title area of the column?
 
end;
??

Thanks

Ted

Just answered this myself...the StringGrid properties has a
'ColumnClickSorts' which I can just set to true.

Amazingly cool.

Thanks

In v1.1 using FPC 2.6.1+, yes. I have created a second SG and applied
the same property.
