首先怎樣彈出界面庫(kù)的菜單呢？
首先模塊向主窗口發(fā)出彈出菜單請(qǐng)求，然后在主程序中收到請(qǐng)求后向發(fā)出請(qǐng)求模塊詢問(wèn)菜單，模塊加載菜單返回然后由主窗口調(diào)用函數(shù)彈出菜單。
//定義查詢菜單的消息
const UINT WM_GETCONTEXTMENU = ::RegisterWindowMessage(_T("GetContextMenu"));
//模塊需要彈出菜單時(shí)向主窗口發(fā)送請(qǐng)求
::SendMessage(hMainWnd, WM_CONTEXTMENU, (WPARAM)m_hWnd,
MAKELPARAM(point.x, point.y));
//主窗口響應(yīng)處理
BEGIN_MESSAGE_MAP(CMainFrame, CMDIChildWndEx)
..
ON_WM_CONTEXTMENU()
END_MESSAGE_MAP()
void CMainFrame::OnContextMenu(CWnd* pWnd, CPoint point)
{
HMENU hMenu(0);
if (pWnd)
{
hMenu = (HMENU)pWnd->SendMessage(WM_GETCONTEXTMENU);
}
if (hMenu)
{
theApp.GetContextMenuManager()->ShowPopupMenu(
hMenu, point.x, point.y, pWnd, TRUE);//注意此處參數(shù)，否則模塊無(wú)法處理命令
}
//以下可根據(jù)情況注釋掉
else
{
CMFCPopupMenu* pMenuActive = CMFCPopupMenu::GetActiveMenu();
if (pMenuActive != NULL)
{
pMenuActive->SendMessage(WM_CLOSE);
}
}
}
//模塊收到主窗口菜單詢問(wèn)加載菜單
BEGIN_MESSAGE_MAP(CXXXXDlg, CDialog)
ON_REGISTERED_MESSAGE(WM_GETCONTEXTMENU, &CXXXXDlg::OnGetContextMenu)
END_MESSAGE_MAP()
LRESULT CXXXXDlg::OnGetContextMenu(WPARAM wParam, LPARAM lParam)
{
HMENU hMenu = ::LoadMenu(..);
return (LRESULT)hMenu;
}
BCGControlBar以及VC2008FeaturePack在菜單中添加圖標(biāo)一般來(lái)說(shuō)需要在資源里添加一個(gè)專門的Toolbar工具條資源 然后調(diào)用AddToolBarForImageCollection這個(gè)方法來(lái)加載圖標(biāo)，此種方法適合資源都在主工程時(shí)使用。
如果是其他模塊請(qǐng)求主程序彈出菜單時(shí)這時(shí)候怎么增加菜單圖標(biāo)？
我們可以利用在菜單中增加自定義的數(shù)據(jù)來(lái)保存圖標(biāo)，當(dāng)然也可以直接設(shè)置菜單圖標(biāo)，這里我只以在菜單使用自定義數(shù)據(jù)為例子。
//在發(fā)送彈出菜單請(qǐng)求時(shí)設(shè)置好菜單的圖標(biāo)
int nCount = GetMenuItemCount(m_hContext);
MENUITEMINFO menuInfo;
menuInfo.cbSize = sizeof MENUITEMINFO;
menuInfo.wID = 0;
menuInfo.fMask = MIIM_ID | MIIM_DATA;
for (int i(0); i < nCount; i++)
{
::GetMenuItemInfo(m_hContext, i, TRUE, &menuInfo);
menuInfo.dwItemData = (ULONG_PTR)m_mMeunIcon[menuInfo.wID];
SetMenuItemInfo(m_hContext, i, TRUE, &menuInfo);
}
ok圖標(biāo)已經(jīng)設(shè)置好了，然后需要在CMainframe中增加一個(gè)虛函數(shù)的實(shí)現(xiàn)即可
函數(shù)原型是
virtual BOOL OnDrawMenuImage ( CDC* pDC,
const CMFCToolBarMenuButton* pMenuButton,
const CRect& rectImage);
實(shí)現(xiàn):
BOOL CMainFrame::OnDrawMenuImage ( CDC* pDC,
const CMFCToolBarMenuButton* pMenuButton,
const CRect& rectImage)
{
ASSERT_VALID (pDC);
ASSERT_VALID (pMenuButton);
if (pMenuButton->m_dwdItemData)
{
CRect rc = rectImage;
rc.DeflateRect(2, 3);
::DrawIconEx(pDC->m_hDC, rc.left, rc.top, (HICON)pMenuButton->m_dwdItemData,
rc.Width(), rc.Height(), 0, NULL, DI_NORMAL);
return TRUE;
}
return FALSE;
} 以上代碼為VC2008FeaturePack環(huán)境，在bcg環(huán)境下類似只需要替換相應(yīng)的函數(shù)即可
