An application typically calls TrackPopupMenuEx in a window procedure in response to a user-generated message, such as WM_LBUTTONDOWN or WM_KEYDOWN. To use a shortcut menu in an application, pass its handle to the TrackPopupMenuEx function. Return DefWindowProc(hwnd, uMsg, wParam, lParam) Test for the identifier of a command item. LRESULT APIENTRY MainWndProc(HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam) Make the window visible and send a WM_PAINT message to the WS_OVERLAPPEDWINDOW, CW_USEDEFAULT, CW_USEDEFAULT,ĬW_USEDEFAULT, CW_USEDEFAULT, NULL, NULL, hinstance, Hwnd = CreateWindow("MainWClass", "Sample Application", that the system uses the class menu for the window.

The following example shows how to create a class menu for an application, create a window that uses the class menu, and process menu commands in the window procedure.įollowing is the relevant portion of the application's header file: // Menu-template resource identifierįollowing are the relevant portions of the application itself: HINSTANCE hinst To create a class menu, include the identifier of the menu-template resource as the lpszMenuName member of a WNDCLASS structure and then pass a pointer to the structure to the RegisterClass function. You cannot assign a menu to a window that is a child window.
Then, when you create a window of the specified class, the system automatically assigns the specified menu to the window. The template identifies the specified menu as the class menu for that window class. To have the system automatically assign a specific menu to a window, specify the menu's template when you register the window's class. Another way you can assign a menu to a window is to specify a menu template when you register a window class the template identifies the specified menu as the class menu for that window class. To assign a menu to a window, use the SetMenu function or specify the menu's handle in the hMenu parameter of the CreateWindowEx function when creating a window. This is useful if your application generates menu templates dynamically. To create a menu from a menu template that is already in memory, use the LoadMenuIndirect function. This window becomes the menu's owner window, receiving all the messages generated by the menu. The LoadMenu function returns a menu handle that you can use to assign the menu to a window. To load a menu-template resource, use the LoadMenu function, specifying a handle to the module that contains the resource and the menu template's identifier. An old menu-template resource has the RT_MENU resource type.Īn old menu template consists of a MENUITEMTEMPLATEHEADER structure followed by one or more MENUITEMTEMPLATE structures. Old Menu-Template FormatĪn old menu template (Microsoft Windows NT 3.51 and earlier) defines a menu, but does not support the new menu functionality.
The system distinguishes the two resource formats by the version number, which is the first member of the resource header.Īn extended menu template consists of a MENUEX_TEMPLATE_HEADER structure followed by one more MENUEX_TEMPLATE_ITEM item definition structures. Like standard menu-template resources, extended menu-template resources have the RT_MENU resource type. The extended menu-template format supports additional menu functionality. For information about creating a menu-template resource, see the documentation included with your development tools. This section describes the format of a menu template, and explains how to load a menu-template resource and use it in your application. You typically include a menu in an application by creating a menu-template resource and then loading the menu at run time.
