CMFCRibbonColorComboBox 设置所选项目的背景颜色

Question

如何从 CMFCRibbonComboBox 导出我的 class CMFCRibbonColorComboBox 并覆盖 OnDrawDropListItem?

如何在选择后为所选项目设置背景颜色。

BOOL CMFCRibbonColorComboBox::OnDrawDropListItem(CDC* pDC, int nIndex, CMFCToolBarMenuButton* pItem, BOOL bHighlight)
{
    ASSERT_VALID(this);
    CRect rc = pItem->Rect();
    LPCTSTR lpszText = GetItem(nIndex);
    if (lpszText == NULL)
    {
        return FALSE;
    }
    CString strText = lpszText;
    pDC->DrawText(strText, rc, DT_SINGLELINE | DT_VCENTER);
    return TRUE;
}

Answer 1

CMFCRibbonComboBox class 派生自 CMFCRibbonEdit 派生自 CMFCRibbonButton。据我所知，您需要覆盖 virtual COLORREF CMFCRibbonButton::OnFillBackground(CDC* pDC)
