改变sdi生成界面的边框的颜色.txt

vc使用技巧汇集

【问题】请问如何改变SDI生成界面的边框的颜色？
假设你的SDI工程所生成的view类为:CSDIFrameColorView,从CView派生.
1:在SDIFrameColorView.h中,增加成员函数:
public:
    void DrawFrameColor(HWND hWnd,COLORREF refColor);
2:在SDIFrameColorView.cpp中
2.1实现DrawFrameColor函数
void CSDIFrameColorView::DrawFrameColor(HWND hWnd,COLORREF refColor)
{    RECT stRect;
    // Get the coordinates of the window on the screen
    ::GetWindowRect(hWnd, &stRect);
     // Get a handle to the window's device context
    HDC hDC = ::GetWindowDC(hWnd);
    HPEN hPen;
    hPen = CreatePen(PS_INSIDEFRAME, 2* GetSystemMetrics(SM_CXBORDER), refColor);
        // Draw the rectangle around the window
    HPEN   hOldPen   = (HPEN)SelectObject(hDC, hPen);
    HBRUSH hOldBrush = (HBRUSH)SelectObject(hDC, GetStockObject(NULL_BRUSH));
        Rectangle(hDC, 0, 0, (stRect.right - stRect.left), (stRect.bottom - stRect.top));
    //Give the window its device context back, and destroy our pen
    ::ReleaseDC(hWnd, hDC);
    SelectObject(hDC, hOldPen);
    SelectObject(hDC, hOldBrush);
    DeleteObject(hPen);
    DeleteObject(hDC);
}
2.2重载OnDraw
void CSDIFrameColorView::OnDraw(CDC* pDC)
{
    CSDIFrameBorderDoc* pDoc = GetDocument();
    ASSERT_VALID(pDoc);
    // TODO: add draw code for native data here
    CWnd* pWnd = GetParent();
    if(pWnd)
    {            DrawFrameColor(pWnd->m_hWnd,RGB(255,0,0));//红色边框
  }
}
