動態(tài)的替換菜單使用如下方法

其實CBCGPMenuBar是繼承于CBCGPToolBar，菜單可以看作是按鈕來替換

在其加載時即可替換

CMainFrame中創(chuàng)建的CBCGPMenuBar

CBCGPMenuBar m_wndMenuBar;

替換

m_wndMenuBar.ReplaceButton(ID_XXX, CBCGPToolbarMenuButton(IDS_EDIT_MYITEM_1, NULL, -1, _T("&MyItem 1")), FALSE);
m_wndMenuBar.AdjustSizeImmediate();

另一種方法

在CMainFrame中重寫

virtual BOOL OnShowPopupMenu (CBCGPPopupMenu* pMenuPopup)
...{
??? //------------- Example --------------------//

??? // we need to find {Dynamic Command} menu item (it's a dummy item)
??? // that should be replaced to our dynamic menu items
??? // in customize mode we should leave the menu as is
??? int iIndex = -1;
??? if (!CBCGPToolBar::IsCustomizeMode () &&
??????? (iIndex = pMenuPopup->GetMenuBar ()->CommandToIndex (ID_DYNAMIC_COMMANDS)) >= 0)
??? ...{
??????? // remove the {Dynamic Command} item in noncustomize mode
??????? pMenuPopup->RemoveItem (iIndex);

??????? pMenuPopup->InsertSeparator (iIndex); // insert the separator at the end
??????? // IDS_EDIT_MYITEM_1 and IDS_EDIT_MYITEM_1 should be defined in the string table
??????? // for status text and tooltip
??????? pMenuPopup->InsertItem (
??????????? CBCGPToolbarMenuButton (IDS_EDIT_MYITEM_1, NULL, -1, _T("&MyItem 1")), iIndex + 1);
??????? pMenuPopup->InsertItem (
??????????? CBCGPToolbarMenuButton (IDS_EDIT_MYITEM_2, NULL, -1, _T("MyItem &2")), iIndex + 2);

??????? // don't forget to add message handlers (ON_COMMAND) to the message map
??? }

??? //-------------------------------------------//

??? return TRUE;
}

任意位置彈出右鍵菜單的方法
在需要彈出位置使用如下方法

...{
??? CPoint pt;
??? GetCursorPos(&pt); //取鼠標位置

??? HMENU hMenu = ::CreatePopupMenu();

??? AppendMenu(hMenu, MF_STRING, 10001, "打開任務處理對話框");
??? AppendMenu(hMenu, MF_STRING, 10002, "定義顏色與圖像");
??? AppendMenu(hMenu, MF_STRING, 10003, "恢復默認設置");

??? theApp.GetContextMenuManager ()->ShowPopupMenu (
??????? hMenu, pt.x, pt.y, this,
??????? TRUE);
}

為菜單添加圖片
首先需要在資源中增加toolbar，來收集需要圖片的菜單項，在toolbar資源中ID與需要圖片的菜單ID一致且按圖片順序排列于toolbar資源上，然后在CMainFrame中OnCreate中加入

// IDR_MENUIMAGE為菜單toolbar資源IDB_BMPMENU菜單圖片
CBCGPToolBar::AddToolBarForImageCollection(IDR_MENUIMAGE, IDB_BMPMENU);
另一種方法
在CMainFrame中重寫

virtual BOOL OnDrawMenuImage (??? CDC* pDC,
????????????????????????????? const CBCGPToolbarMenuButton* pMenuButton,
????????????????????????????? const CRect& rectImage)
...{
??? ASSERT_VALID (pDC);
??? ASSERT_VALID (pMenuButton);

??? if (pMenuButton->m_nID == ID_DYNAMIC_ITEM_2)//ID_DYNAMIC_ITEM_2為菜單項ID
??? ...{
??????? // 請加載菜單圖片或圖標然后自己繪制
??????? CBrush br (RGB (0, 0, 255));???
??????? CRect rect = rectImage;
??????? rect.DeflateRect (2, 2);

??????? pDC->FillRect (rect, &br);
??????? return TRUE;
??? }
}

其它特色方法可以參考安裝目錄BCGSoft\BCGControlBarPro\Samples\下的例子
