All components in Delphi are objects, so Create and Destroy have to be used for creating and destroying of the component at runtime. A problem with TTabbedNotebook in a correct placement of control on appropriate page.
The process of adding controls to a TNotebook is almost exactly the same as that for TTabbedNotebook - only the page class type is TPage instead of TTabPage.
So we can do:
uses Tabnotbk;
...
procedure TForm1.Button1Click(Sender: TObject);
var
TabPage: TTabPage;
Button: TButton;
begin
with TabbedNotebook1 do
TabPage:=TTabPage(Pages.Objects[PageIndex]);
Button:=TButton.Create(TabPage);
try
with Button do begin
Parent:=TabPage;
Left:=Random(TabPage.ClientWidth-Width);
Top:=Random(TabPage.ClientHeight-Height);
end;
except
Button.Free;
end;
end;
