How to check a popup menu item?

Question

如何检查弹出菜单项？

Answer 1

using CMenu::CheckMenuItem

See the example in MSDN .

Answer 2

在上下文菜单的情况下，使用AppendMenu（）函数向菜单添加项目时使用MF_CHECKED样式。

Answer 3

When you create a popup menu entry there is no command number and you can only use MF_BYPOSITION parameter.

For example if you have menu created with

HMenu = CreateMenu();

And a Menu entry "Edition" where you have "Select..." with 3 choices :

HPopSubMenuSelect = CreatePopupMenu();
AppendMenu(HPopSubMenuSelect, MF_STRING, 20, "All");
AppendMenu(HPopSubMenuSelect, MF_STRING, 21, "Word");
AppendMenu(HPopSubMenuSelect, MF_STRING, 22, "Nothing");
HPopMenuEdition = CreatePopupMenu();
AppendMenu(HPopMenuEdition, MF_STRING | MF_POPUP , HPopSubMenuSelect,"Select...");
AppendMenu(HMenu, MF_STRING | MF_POPUP , HPopMenuEdition, "Edition");

Then to check this you must call

CheckMenuItem(HPopMenuEdition, 1, MF_BYPOSITION | MF_CHECKED);
// Or for uncheck
// CheckMenuItem(HPopMenuEdition, 1, MF_BYPOSITION | MF_UNCHECKED);
