Hello Jesper,
Of course you can use the Objects property of the
ComboBox's Items property. Here is some code snippet
for populating the combobox and find the selected
object.
procedure PopulatingCombo(AComboBox: TComboBox; AList:
TList);
begin
AComboBox.Clear;
for i := 0 to AList.Count-1 do
AComboBox.Items.AddObject(TMyObject(AList[i]).Name,
TMyObject(AList[i]));
end;
procedure FormXXX.Combo1Click(Sender: TObject);
begin
if Combo1.ItemIndex > -1 then
MyActiveObject :=
TMyObject(Combo1.Items.Objects[Combo1.ItemIndex])
else
MyActiveObject := nil;
end;
Btw, if you want to know more about the Objects
property, you can read Delphi Help for TStrings class.
For Items property of TComboBox is aTStrings
descendant.

Luthfi B Hakim
