WkeWebKit.cpp 新增 wkeSetTransparent(m_pWebView, true);

void CWkeWebkitUI::DoInit()
{
    CControlUI::DoInit();
    // 设置UA
    wkeSetUserAgent(m_pWebView, "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/52.0.2228.0 Safari/537.36");
    // 设置名称
    wkeSetName(m_pWebView, T2ANSI(GetName()).c_str());
    // 设置窗口透明
    wkeSetTransparent(m_pWebView, true);
    // 启动定时器
    SetTimer(EVENT_TICK_TIEMER_ID, 30);
    // 初始化后回调接口
    wkeOnTitleChanged(m_pWebView, OnWkeTitleChanged, this);
    wkeOnURLChanged(m_pWebView, OnWkeURLChanged, this);
    wkeOnNavigation(m_pWebView, OnWkeNavigation, this);
    wkeOnCreateView(m_pWebView, OnWkeCreateView, this);
    wkeOnDocumentReady(m_pWebView, OnWkeDocumentReady, this);
    wkeOnLoadingFinish(m_pWebView, OnWkeLoadingFinish, this);
}

// 以及 void CWkeWebkitUI::DoPaint(HDC hDC, const RECT& rcPaint) 中
// ::BitBlt(hDC, m_RendData.rt.left, m_RendData.rt.top, m_RendData.rt.right - m_RendData.rt.left, m_RendData.rt.bottom - m_RendData.rt.top, m_RendData.hDC, 0, 0, SRCCOPY);
// 修改为
BLENDFUNCTION bf = { AC_SRC_OVER, 0, 0xFF, AC_SRC_ALPHA };
::AlphaBlend(hDC, m_RendData.rt.left, m_RendData.rt.top, m_RendData.rt.right - m_RendData.rt.left, m_RendData.rt.bottom - m_RendData.rt.top, m_RendData.hDC, 0, 0, m_RendData.rt.right - m_RendData.rt.left, m_RendData.rt.bottom - m_RendData.rt.top, bf);
否则会出现wke窗口透过程序窗口直接看到桌面
