listctrl调整表头高度

CListCtrl派生类下CMyListCtrl.h

class CMyListCtrl :public CListCtrl

{

    public:

   // 设置表头高度

    void SetHeadHeight(float Height);

}

void CMyListCtrl::SetHeadHeight(float Height)

{

    m_Head.m_fHeight = Height;

}

CHeaderCtrl派生类CMyHeadCtrl插入HDM_LAYOUT消息

class CMyHeadCtrl :public CHeaderCtrl

{

    LRESULT OnLayout(WPARAM wParam, LPARAM lParam);

}

BEGIN_MESSAGE_MAP(CMyHeadCtrl, CHeaderCtrl)

     ON_MESSAGE(HDM_LAYOUT, OnLayout)

END_MESSAGE_MAP()

CMyHeadCtrl::CMyHeadCtrl() :

{

    m_fHeight = 1.5;    //默认列头高度是一倍数

}

LRESULT CMyHeadCtrl::OnLayout(WPARAM wParam, LPARAM lParam)

{

    LRESULT lResult = CHeaderCtrl::DefWindowProc(HDM_LAYOUT, , lParam);

    HD_LAYOUT &hdl = *(HD_LAYOUT *)lParam;

    RECT *prc = hdl.prc;

    WINDOWPOS *pwpos = hdl.pwpos;

    //表头高度为原来1.5倍，如果要动态修改表头高度的话，将1.5设成一个全局变量

    int nHeight = (int)(pwpos->cy * m_fHeight);

    pwpos->cy = nHeight;

    prc->top = nHeight;

    return lResult;

}
