动态菜单使用mfc [英] Dynamic menu using mfc

问题描述

我想在我的主菜单中添加一个菜单项，然后在运行时用项目填充它。我该怎么做？

I would like to add a menu item to my main menu and then populate it with items at run time. How would I do this? And besides adding items how would I have a message map entry for them since I do not know the id?

推荐答案

除了添加项目，我还有一个消息映射条目，因为我不知道id。 CMenu 对象动态如下：

You can create a CMenu object dynamically like this:

CMenu *menu = new CMenu;
menu->CreatePopupMenu();
// Add items to the menu
menu->AppendMenu(MF_STRING, menuItemID, "Text");
...

然后将此子菜单添加到主菜单：

Then add this sub-menu to your main menu:

wnd->GetMenu()->AppendMenu(MF_POPUP, (UINT_PTR)menu->m_hMenu, "Menu Name");

对于消息映射，假设所有菜单项ID都在一定范围内， ON_COMMAND_RANGE 以将整个范围映射到单个函数。此函数将接收ID作为参数，在函数中，您可以根据ID执行不同的操作。

As for the message map, assuming all your menu item IDs are within a certain range, you can use ON_COMMAND_RANGE to map the entire range to a single function. This function will receive the ID as a parameter, and within the function, you can perform different operations based on the ID.
