推荐答案

class CYourCtrl : public CListCtrl
{
public:
  CYourCtrl();
  virtual ~CYourCtrl();
protected: 
  //{{AFX_MSG(CYourCtrl) 
  virtual void DrawItem       (LPDRAWITEMSTRUCT);
  afx_msg void MeasureItem    (LPMEASUREITEMSTRUCT);    
  //}}AFX_MSG
  DECLARE_MESSAGE_MAP()
};

...
BEGIN_MESSAGE_MAP(CYourCtrl, CListCtrl)
    ON_WM_MEASUREITEM_REFLECT()    
END_MESSAGE_MAP()

//
void CYourCtrl::MeasureItem(LPMEASUREITEMSTRUCT lpMeasureItemStruct)
{
  if (lpMeasureItemStruct) {
    lpMeasureItemStruct->itemHeight = ...; // set your hight here
  }
}

请记住设置LVS_OWNERDRAWFIXED
在创建控件或在.rc文件中时:)

Please remember to set the LVS_OWNERDRAWFIXED
at creating of your control or in your .rc file :)

void CYourCtrl::DrawItem(LPDRAWITEMSTRUCT pDIS)
{
  if (pDIS) {
    // the first step
    if (ODA_DRAWENTIRE == pDIS->itemAction) {
      // Draw your content here
    }
    // there are other cases too :)
  }
}
