关于SetMenuItemInfo

[shadowstory80]

我用下面的方法设置“最近文件“重画，SetMenuItemInfo的返回值为1 但是“最近文件“没有重画，不知道到为什么？
请各位指教,谢谢！

void CMainFrame::OnInitMenuPopup(CMenu* pPopupMenu, UINT nIndex, BOOL bSysMenu)
{
CMDIFrameWnd::OnInitMenuPopup(pPopupMenu, nIndex, bSysMenu);
if(bSysMenu) {
return;
}
int n = 0;
int nIndexMax = pPopupMenu-> GetMenuItemCount();
int nID = 0;
for(nIndex = 0;nIndex < nIndexMax;nIndex++) {
nID = pPopupMenu->GetMenuItemID(nIndex);
MENUITEMINFO MenuItemInfo;
//TCHAR szBuf[255];
//memset(szBuf,0,sizeof(szBuf));
memset(&MenuItemInfo,0,sizeof(MenuItemInfo));
MenuItemInfo.cbSize = sizeof (MENUITEMINFO);
MenuItemInfo.fMask = MIIM_DATA |MIIM_STATE | MIIM_ID;// ?个?型很??

if(nID >= 57616 && nID <= 57631 ) {
n = GetMenuItemInfo(pPopupMenu->m_hMenu ,nID,FALSE,&MenuItemInfo);
MenuItemInfo.fType |= MF_OWNERDRAW;
n = SetMenuItemInfo(pPopupMenu->m_hMenu ,nID,FALSE,&MenuItemInfo);
}
}
}

CWnd::OnInitMenuPopup
afx_msg void OnInitMenuPopup( CMenu* pPopupMenu, UINT nIndex, BOOL bSysMenu );

Parameters

pPopupMenu

Specifies the menu object of the pop-up menu. May be temporary and should not be stored for later use.

nIndex

Specifies the index of the pop-up menu in the main menu.

bSysMenu

TRUE if the pop-up menu is the Control menu; otherwise FALSE.


1。还需要处理WM_MEASUREITEM WM_DRAWITEM消息

2。SetMenuItemInfo之前要设置MenuItemInfo.fMask |＝MIIM_TYPE

3。另外：
你的nIndex用法不好
而且没必要整个主菜单所有弹出菜单都遍历一回，因为recent files 一般都放在 nIndex ＝＝ 1的弹出菜单里面

[willson93639450]

不好意思 主菜单第一个弹出菜单索引应该是0，不是1。上面搞错了
