Hi!!
I got the following message map.
OnExtMenuPrepare and OnDrawPopupMenuItem method are called
but OnDrawPopupLeftArea method is not called.
I just followed an example given.
Any idea ?
Thanks.
BEGIN_MESSAGE_MAP(CChildFrame, CMDIChildWnd)
///
ON_REGISTERED_MESSAGE(CExtPopupMenuWnd::g_nMsgPrepareMenu, OnExtMenuPrepare)
ON_REGISTERED_MESSAGE(CExtPopupMenuWnd::g_nMsgPopupDrawItem, OnDrawPopupMenuItem)
ON_REGISTERED_MESSAGE(CExtPopupMenuWnd::g_nMsgPopupDrawLeftArea, OnDrawPopupLeftArea)
END_MESSAGE_MAP()

The popup menus displayed from the menu bar in your application send their notification messages to the main frame window only and you should resend the needed messages to the active MDI child frame manually and exactly as it is demonstrated in the DRAWCLI sample. The context menus send their messages to the window handle which was specified when invoking the CExtPopupMenuWnd::CreatePopupMenu(), CExtPopupMenuWnd::LoadMenu() or CExtPopupMenuWnd::UpdateFromMenu() methods.

g_nMsgPopupDrawLeftArea message is sent only if you give a width for the left area:
CExtPopupMenuWnd * pPopup = new CExtPopupMenuWnd;
pPopup->SetLeftAreaWidth( 30 );
Another thing: this left area is not the area where the icons of the command items are displayed, but some additional left area drawn when the width of it is set with SetLeftAreaWidth. Hope that helps.
