-------------------------------------------------- ------------------------------ Related menus and accelerator key menu is the most important component of the Windows standard interface, the menu of the window The strip is located below the title bar, which is often referred to as the main menu, and the menu item below the main menu is called a drop-down menu, or the pop-up menu, submenu, etc., and click on the left side of the title bar. A menu will pop up, called the system menu. The accelerator is actually a shortcut key of the menu item, and the application often marks the shortcuts of the menu item on the right side of the menu item, which is the accelerator button. The structure of the menu is nested, that is, you can pop up another menu when you select a menu item. The type of menu item is normal, disabled, ash, horizontal separation line, etc. This section demonstrates various types of menus: You can see normal and disabled, gray menu in the main menu, you can use the right-click window to pop up a "pop-up menu", too I can see that I have added a few new content in the system menu. In programming processing, the menu is defined in the resource file (of course, you can use the resource file, and use the AppendMenu one item in the program, but use the resource file is undoubtedly the easiest way), then Use loadMenu to get the menu handle to use. The syntax of the menu in the resource file is as follows: Menu ID Menu DiscardableBeginPopup "Main menu item 1" BeginMenuItem "pop-up menu item one", command ID [, option] MenuItem "pop-up menu item 2", command ID [, option] MenuItem SeparatorNuItem "Pop-up Menu item 3", command id [, option] ... Endpopup "Main menu item 2" BeginMenuItem "pop-up menu item 1", command ID [Option] MenuItem "pop-up menu item 2", Command ID [, Option] MenuItem "pop-up menu item three", command id [, option] ... Popup "Nested menu item" BeginMenuItem "pop-up menu item", command id [, option] menuitem "pop-up Menu item 2 ", command ID [, option] menuItem" pop-up menu item three ", command ID [, option] ... Endend ... End menu ID is what we use to load menu in the program with loadMenu Resource number, MenuItem Separator defines the horizontal line with the separated menu item, the option in the menu item definition is attribute, such as grayed is ashing, INACTIVE is disabled.
The accelerator is actually defined corresponding to the hotkey corresponding to each menu item, the definition method is as follows: Accelerator ID acceleratorsbeginvk_f1, the corresponding menu command ID, Virtkeyvk_f2, the corresponding menu command ID, Virtkey ... "a", corresponding Menu Command ID, Virtkey, Control "B", the corresponding menu command id, Virtkey, Controlend where the accelerator key ID is our resource number we loaded with the loadAclerator in the program, and each item below defines a key. VK_F1 represents the use of F1, "a" to indicate the key A, the following Virtkey is required, then the control "or shift, alt" indicates the combination of CONTROL keys, that is, if you define: "c", idm_copy, Virtkey, Control and define menuItem "copy" in the menu definition, IDM_COPY, then pressing Ctrl-C in the program, actually executing the menu item "copy". The programming of the menu and accelerator is very simple. Initialization, you need to do the following: Make the program's instance handle (hinstance) to load the menu, get the menu handle with the loadaccelerator to load the accelerator button, get the accelerator key handle registration window Class Create a window When you create a menu handle display window, then enter the message loop, with TranslateAccelerator with translateAccelerator (see the source program) When the window is displayed, when a menu item or a accelerator button is pressed When Windows sends a WM_COMMAND message to the window process, when the menu item in a system menu is pressed, Windows sends WM_SYSCOMMAND to the window process, the ID of the menu item is included in the low 16 bits of WPARAM, in general Programming, if we do not process the system menu message, just create a section in the process of the WM_COMMAND message. The statement of each menu command ID is processed.

If so, it looks for the accelerator key table corresponding to the handle @haccelerator. If a match is found, then it will send a WM_COMMAND message with the command ID, At the same time, it returns a non-0 value. At this time, the message has been processed, no need to call the following translateMessage and DispatchMessage, if not, then it will return 0, the message loop continues.
