Hello,
I was implementing TMenu for Qt, when I got a little confused by
component arrays.
On the file menu.inc I see this:
procedure TMenu.CreateHandle;
var i: integer;
begin
FItems.Handle := TWSMenuClass(WidgetSetClass).CreateHandle(Self);
// initiate creation of subitems
// Note: FItems is a TMenuItem. Using HandleNeeded will create all subitems.
for i:=0 to Items.Count-1 do
if Items[i].Visible then
Items[i].HandleNeeded;
end;
And here is how Items is declared on this class:
FItems: TMenuItem;
..............
property Items: TMenuItem read FItems;
My doubts are:
1 ) Can I just take a property and use it as an array like that??
Shouldn't that property be declared like this:
property Items[Index: Integer]: TMenuItem read FItems;
2) And if it was declared like above, shouldn't FItems be an array of
TMenuItem ?
Are TComponent descendents naturally arrayable or something like that?
thanks,
