base control that has a popupMenu

A function in one of my Delphi 2010 libraries creates a TPopupMenu on the fly. I need to create a procedure that lets me pass a control to associate the menu with. For example, a TEdit has a PopupMenu property, as does a TMemo, a TcxDbTreeList, etc. I obviously don't want to write a separate overloaded procedure for every control type that I'll ever want to associate my menu with, but I can't figure out what base class that lets me set the Popupmenu property. For example, I can't write
if Sender is TWinControl then TWinControl(Sender).popupMenu := myMenu;

Open in new window

because TWinControl doesn't have the PopupMenu property. What class base supports the PopupMenu property?.  Thanks much.

I take example from: http://delphi.about.com/od/adptips2005/qt/setdatasource.htm
...and modified a little:
procedure ApplyPopupMenu(myCtrls: array of TControl; pm: TPopupMenu);
var
   cnt: Integer;
   PropInfo: PPropInfo;
begin
   for cnt := Low(myCtrls) to High(myCtrls) do
   begin
     PropInfo := GetPropInfo(myCtrls[cnt].ClassInfo, 'PopupMenu') ;
     if Assigned(PropInfo) then
       SetOrdProp(myCtrls[cnt], PropInfo, LongInt(pm)) ;
   end;
end;

procedure TForm1.Button12Click(Sender: TObject);
begin
  ApplyPopupMenu([VirtualStringTree1, DBGrid1, Memo1], PopupMenu1);
end;

Open in new window


This will set popupmenu for all components in call (if property PopupMenu exist) using Rtti functions.

Thanks, Sinisa. In this case, I only need to pass one TControl, but this was helpful in getting and setting the desired property. (Seems a little convoluted that those properties would be that awkward to get to, but that's another issue.)
