问题描述
我在从CMFCPopupMenu获取选定的命令ID时遇到麻烦.有一个成员函数:
CMFCToolBarMenuButton * GetSelItem()，该函数应该返回指向当前所选菜单命令的指针，但是，我总是从该函数获取NULL.以下是我使用的代码，请帮忙！
CMFCPopupMenu * pPopupMenu = new CMFCPopupMenu;
if(pPopupMenu-> Create(pWnd，point.x，point.y，hMenu)){
CMFCToolBarMenuButton * button = pPopupMenu-> GetSelItem();
....
}
hMenu是正确的菜单句柄，而pWnd是弹出菜单的父窗口.但是，无论用户选择菜单的哪个命令，按钮始终为NULL.
非常感谢！
Hi, I'm having trouble getting the selected command ID from CMFCPopupMenu. There is a member function:
CMFCToolBarMenuButton *GetSelItem(), which is supposed to return a pointer to the currently selected menu command, however, I always get NULL from this function. Below is the code I use, Please help!
CMFCPopupMenu* pPopupMenu = new CMFCPopupMenu;
if(pPopupMenu->Create(pWnd, point.x, point.y, hMenu)){
CMFCToolBarMenuButton *button = pPopupMenu->GetSelItem();
....
}
hMenu is the proper menu handle and pWnd is the parent window of the popup menu. However button is always NULL, no matter which command of the menu is selected by user.
Thanks a lot!
