O Windows 10 e 11 t\u00eam seu pr\u00f3prio sistema de notifica\u00e7\u00e3o. Em uma vers\u00e3o recente do Delphi, foi adicionado um componente chamado TNotificationCenter<\/code>. Adicione-o ao seu formul\u00e1rio e voc\u00ea poder\u00e1 exibir notifica\u00e7\u00f5es nativas do Windows.<\/p>\n

Para tratar um clique de notifica\u00e7\u00e3o, implementamos OnReceiveLocalNotification<\/code><\/p>\n
\n
procedure<\/span> TForm1<\/span>.<\/span>NotificationCenter1ReceiveLocalNotification<\/span>(Sender:<\/span> TObject<\/span>;<\/span> ANotification:<\/span> TNotification);<\/span>\r\nbegin<\/span>\r\n  if<\/span> ANotification.<\/span>Number =<\/span> UPDATE_NOTIFICATION_ID  then<\/span>\r\n  begin<\/span>\r\n    InstallUpdate;<\/span>\r\n  end<\/span>;<\/span>\r\nend<\/span>;<\/span>\r\n<\/pre>\n<\/div>\n
 
\nPara agendar uma notifica\u00e7\u00e3o, usamos NotificationCenter.ScheduleNotification<\/code><\/p>\n
\n
procedure<\/span> ScheduleNotification<\/span>;<\/span>\r\nvar<\/span>\r\n  Notification:<\/span> TNotification;<\/span>\r\nbegin<\/span>\r\n  Notification :=<\/span> NotificationCenter1.<\/span>CreateNotification;<\/span>\r\n  Notification.<\/span>AlertBody :=<\/span> 'It<\/span>''<\/span>s time to drink coffee :-)'<\/span>;<\/span>\r\n  Notification.<\/span>FireDate  :=<\/span> IncHour(Now<\/span>);<\/span>\r\n  \r\n  NotificationCenter1.<\/span>ScheduleNotification(Notification);<\/span>\r\nend<\/span>;<\/span>\r\n<\/pre>\n<\/div>\n
