I hardly get it.

I’d appreciate any help in understanding how to add/remove dynamically menu items and submenus.

Thanks and congratulations.

Dear Micro,


Prof-UIS allows you to dynamically construct any menu in the application. The library notifies the frame window that the menu is about to be created via the CExtControlBar::g_nMsgPrepareMenu registered window message. The WPARAM parameter is a pointer to the CExtPopupMenuWnd::MsgPrepareMenuData_t structure which describes the menu. CExtPopupMenuWnd::MsgPrepareMenuData_t::m_pPopup keeps a pointer to the CExtPopupMenuWnd object, which can be modified. By analyzing menu items, you should detect whether the popup menu is one that you want to modify.


The above described technique is implemented in the DrawCli sample. Please take a look at the CMainFrame::OnExtMenuPrepare() method. It handles the message dealing with dynamic menu construction and redirects it to the active view window. The latter handles this message in the CDrawView::OnExtMenuPrepare() method by modifying the menu before it is drawn.

Thanks for your quick and helpful reply.

I can see indeed how to modify/insert popup menus, but not how to update the main menu items. Moreover, what is still somehow unclear is the role of the Command Manager in these dynamic updates.

Thanks again,

Mirco
