Hi,
I have created a program that handles different files.
Now I want to create a "historymenu" for the most rescent used files.
My problem is how to create new menuitems in my excisting mainmenu.
Anyone any idea?

The Delphi help includes this:  umnudmo.pas

This shows how to programatically build up a TMainMenu, adding new TMenuItems.  The main thrust is, do TMenuItems.Create, then add them to the mainmenu.

from my PAQ (http://www1.experts-exchange.com/bin/Q.10132229)

basically the same...

Q:
How can I create TMenuItems when the application is running?
How can I assign methods to the items created?

Here we go:
>>>>>>>>>>>>>>>>>>>><< 
unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,
  StdCtrls, Menus;

type
  TForm1 = class(TForm)
    MainMenu1: TMainMenu;
    Button1: TButton;
    procedure Button1Click(Sender: TObject);
    procedure ExitClick(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.DFM}

procedure TForm1.Button1Click(Sender: TObject);
var item: TMenuItem;
    item2: tmenuitem;
begin
  item := tmenuitem.create(MainMenu1);
  item.Caption := '&File';
  MainMenu1.Items.Add(item);

  item2 := tmenuitem.create(MainMenu1);
  item2.Caption := 'E&xit';
  item2.OnClick := ExitClick;
  item.Add(item2);

end;

procedure TForm1.ExitClick(Sender: TObject);
begin
  Application.Terminate;
end;

end.
<<<<<<<<<<<<<<<<<<<< 

Don't forget to place a TMainMenu named MainMenu1 and a TButton named Button1 onto your form. Also, please take care to attach the OnClick event to the Button1Click method.

Have fun,
<freter>
