What about fixed size arrays?
var
pFSImage: array[0..3] of pGTKWidget;
i: integer;
begin
for i:= 0 to 3 do
begin
pFSImage[i] := your code here
more code
end;
end;
You could also use dynamic arrays if you don't know the array size at compile
time. There is more information in the reference manual of FPC.
