为什么CMFCPopupMenu避免submeu的状态? [英] Why CMFCPopupMenu avoid submeu's uistate?

问题描述

//Visual Studio 2008 sp 1

当我使用GetContextMenuManager()-> ShowPopupMenu()时，它避免了子菜单的状态.

//ShowPopupMenu(HMENU hmenuPopup，int x，int y，CWnd * pWndOwner，BOOL bOwnMessage = FALSE，BOOL bAutoDestroy = TRUE，BOOL bRightAlign = FALSE);

示例源代码

CMenu menu1，menu2;
menu.CreatePopupMenu();

menu1.AppendMenu(MF_STRING | MF_CHECKED ，WM_USER + 1，_T("A"));
menu2.AppendMenu(MF_STRING | MF_CHECKED ，WM_USER + 2，_T("SubMenu A"));

menu1.AppendMenu(MF_BYCOMMAND | MF_STRING | MF_POPUP，reinterpret_cast< uint_ptr>(menu2.Detach())，_T("Submenu"));

theApp.GetContextMenuManager()-> ShowPopupMenu(menu1.Detach()，x，y，this，TRUE，TRUE);


出现时，选中菜单"A"，但没有选中子菜单A.

没有人知道为什么吗?

//Visual Studio 2008 sp 1

when I use GetContextMenuManager()->ShowPopupMenu(), it avoid submenu''s uistate.

//ShowPopupMenu(HMENU hmenuPopup, int x, int y, CWnd* pWndOwner, BOOL bOwnMessage = FALSE, BOOL bAutoDestroy = TRUE, BOOL bRightAlign = FALSE);

Example source code

CMenu menu1, menu2;
menu.CreatePopupMenu();

menu1.AppendMenu( MF_STRING | MF_CHECKED, WM_USER+1, _T("A") );
menu2.AppendMenu( MF_STRING | MF_CHECKED, WM_USER+2, _T("SubMenu A") );

menu1.AppendMenu( MF_BYCOMMAND | MF_STRING | MF_POPUP, reinterpret_cast<uint_ptr>(menu2.Detach()), _T("Submenu") );

theApp.GetContextMenuManager()->ShowPopupMenu(menu1.Detach(), x, y, this, TRUE, TRUE);


when it appeared, the menu "A" is checked, but SubMenu A wasn''t.

isn''t there anyone know why?

推荐答案

函数

void CMFCToolBarMenuButton::CreateFromMenu(HMENU hMenu)

确实会产生子选单，但无法控制内部的检查状态...

您可以直接插入按钮(很简单)，
或在创建呈现的种类后重新访问某些按钮:)

does produce a submenu, but does not control the checked state inside...

You could insert your buttons directly (it''s easy),
or reaccess some buttons after the creating of presented kind :)

谢谢. :)

实际上，我知道对于子菜单而言，没有任何过程.
其实，我想知道的是他们为什么要这样做?我认为这是某种错误..
