unit Unit1; interface uses Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms, Dialogs, Menus; type TForm1 = class(TForm) procedure FormCreate(Sender: TObject); procedure Proc(Sender: TObject); {声明将要被调用的方法} end; var Form1: TForm1; implementation {$R *.dfm} var MyMenu: TMainMenu; Item: TMenuItem; {实现将要被调用的方法} procedure TForm1.Proc(Sender: TObject); begin if Sender is TMenuItem then ShowMessage(TMenuItem(Sender).Caption); end; procedure TForm1.FormCreate(Sender: TObject); var Itemd: TMenuItem; begin MyMenu := TMainMenu.Create(Self); MyMenu.AutoHotkeys := maManual; Self.Menu := MyMenu; Item := TMenuItem.Create(MyMenu); Item.Caption := ''AA''; MyMenu.Items.Add(Item); Itemd := TMenuItem.Create(MyMenu); Itemd.Caption := ''A&1''; Itemd.OnClick := Proc; {调用方法} Item.Add(Itemd); Itemd := TMenuItem.Create(Item); Itemd.Caption := ''A&2''; Itemd.OnClick := Proc; {调用方法} Item.Add(Itemd); end; end.
效果图: 不过, 菜单事件一般是使用 ActionList 的, 添加一个 ActionList 同时添加一个方法, 实现和上面同样的功能: unit Unit1; interface uses Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms, Dialogs, Menus, ActnList; type TForm1 = class(TForm) ActionList1: TActionList; Action1: TAction; procedure FormCreate(Sender: TObject); procedure Action1Execute(Sender: TObject); end; var Form1: TForm1; implementation {$R *.dfm} var MyMenu: TMainMenu; Item: TMenuItem; procedure TForm1.Action1Execute(Sender: TObject); begin if Sender is TMenuItem then ShowMessage(TMenuItem(Sender).Caption); end; procedure TForm1.FormCreate(Sender: TObject); var Itemd: TMenuItem; begin MyMenu := TMainMenu.Create(Self); MyMenu.AutoHotkeys := maManual; Self.Menu := MyMenu; Item := TMenuItem.Create(MyMenu); Item.Caption := ''AA''; MyMenu.Items.Add(Item); Itemd := TMenuItem.Create(MyMenu); Itemd.Caption := ''A&1''; Itemd.OnClick := Action1Execute; {调用方法} Item.Add(Itemd); Itemd := TMenuItem.Create(Item); Itemd.Caption := ''A&2''; Itemd.OnClick := Action1Execute; {调用方法} Item.Add(Itemd); end; end.
