求救!!!!自画菜单遇到麻烦..所有的2级菜单没有办法调用到MeasureItem.这是偶所有的分了..

Question

谁可以帮我一把.非常感谢了.如何可以.可以把代码发过去..

Answer 1

在这里更改的菜单属性
int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CFrameWnd::OnCreate(lpCreateStruct) == -1)
return -1; m_menu.SetMainWnd(GetSafeHwnd());
CMenu *pMenu = GetMenu();
m_menu.FromHandle(pMenu->GetSafeHmenu());
if (!m_wndToolBar.CreateEx(this, TBSTYLE_FLAT, WS_CHILD | WS_VISIBLE | CBRS_TOP
| CBRS_GRIPPER | CBRS_TOOLTIPS | CBRS_FLYBY | CBRS_SIZE_DYNAMIC) ||
!m_wndToolBar.LoadToolBar(IDR_MAINFRAME))
{
TRACE0("Failed to create toolbar\n");
return -1;      // fail to create
} if (!m_wndStatusBar.Create(this) ||
!m_wndStatusBar.SetIndicators(indicators,
  sizeof(indicators)/sizeof(UINT)))
{
TRACE0("Failed to create status bar\n");
return -1;      // fail to create
} // TODO: Delete these three lines if you don't want the toolbar to
//  be dockable
m_wndToolBar.EnableDocking(CBRS_ALIGN_ANY);
EnableDocking(CBRS_ALIGN_ANY);
DockControlBar(&m_wndToolBar); return 0;

}可是没有调用MeasureItem.我已经写下了Mainframe 的OnMeasureItem里加了的
