[Lazarus] RTTI grid with multiple objects ?

[Michael Van Canneyt via Lazarus]

Hello,

How to make the RTTI property grid display the properties of a set of
TComponents ?

Currently I have: (MyGrid is the property grid)

Var
  I : integer;
  L : TPersistentSelectionList;

begin
  C:=0;
  L:=MyGrid.Selection;
  L.BeginUpdate;
  try
    L.Clear;
    if Not Assigned(ObjectList) then
      exit;
    For I:=0 to ObjectList.Count-1 do
      if ObjectList[i].Selected then
        L.Add(ObjectList[i]);
  finally
    L.EndUpdate;
    Mygrid.RefreshPropertyValues;
  end;
end;

But the grid remains empty, even though I know multiple objects have been
attached. I tried various things, but the grid remains empty.

What should I do so the grid actually shows something ?

Michael.
