It didn't, but does now. :)  Get the latest code from the 'develop' branch.

I didn't like the idea of including hard-coded CSV methods and CSV
processing into the standard StringGrid component, so for fpGUI I
created a StringGridBuilder class that does that for you. This way the
builder class can be extended (new methods added to the original), or a
descendant class created and key methods overridden so it can handle
other file formats too. For example fixed length or TAB delimited files,
or even an ODS (OpenDocument Spreadsheet) file.

Usage:
======

uses
  fpg_StringGridBuilder;

...

var
  sgb: TStringGridBuilder;
begin
  try
    sgb := TStringGridBuilder.CreateCustom(Grid1, edtFile.FileName,
chkHasHeader.Checked);
    sgb.Run;
  finally
    sgb.Free;
  end;
end;


This is actually similar to what I have done in one of my commercial
applications. But instead of a CSV file, the columns (including title &
width) and sort order was driven by a set of "View" classes. You could
have multiple views of the same data objects, by simply selecting the
desired view from a menu. The StringGridBuilder then handled the whole
setup and grid population for you.
