Я добавил значок уведомления в свое диалоговое приложение, и он получил WM_LBUTTONDBLCLK при двойном щелчке по значку, но не получает WM_CONTEXTMENU, когда по щелчку правой кнопкой мыши значок или когда значок подсвечивается с помощью клавиатуры и контекста нажата кнопка меню. Я использовал значок уведомления на примере в примерах SDK для Windows 7.1. Итак, я понятия не имею, где я иду не так или почему это не работает.
Примечание. Если я изменю WM_CONTEXTMENU на WM_RBUTTONUP, он получит событие, но координаты курсора будут неправильными.
