今天發現里一個非常好用的Listbox自繪類，帶不同文字字體和圖片，覺得很有必要記下來

代碼簡寫

MyListBox.h

class CUseListBox : public CListBox
{
    typedef struct _ListBox_Data 
    {
        CString strAppend;    //第二排附加數據
        LPTSTR    hIcon;        //圖標
        _ListBox_Data()
        {
            strAppend = _T("");
            hIcon = NULL;
        }
    } List_AppendData;
public: virtual void DrawItem(LPDRAWITEMSTRUCT /*lpDrawItemStruct*/); virtual void MeasureItem(LPMEASUREITEMSTRUCT /*lpMeasureItemStruct*/);
void InsertStr(CString str,int iIndex,CString strAppend,LPTSTR icon); 
afx_msg void OnDestroy(); afx_msg BOOL OnEraseBkgnd(CDC* pDC); 
afx_msg void OnMouseMove(UINT nFlags, CPoint point);
}

MyListBox.cpp

調用直接InsertStr就行

 

我寫的加載圖片

  CDC* pDC;
        pDC = CDC::FromHandle(lpDrawItemStruct->hDC);

        CBitmap bmp, *pOldBmp;
        HBITMAP bitmap;
        CDC memDC;
        memDC.CreateCompatibleDC(pDC);
        if (pCell)
        {
            CRect rect;
            GetCellRect(pCell->dwRow, pCell->dwCol, rect);
            if (!pCell->FilePathName ==NULL )
            {

           
                BITMAP bm;
                HBITMAP hBitmap = (HBITMAP)::LoadImage(
                    AfxGetInstanceHandle(),
                    pCell->FilePathName,
                    IMAGE_BITMAP,
                    160, 90,
                    LR_DEFAULTCOLOR | LR_CREATEDIBSECTION | LR_LOADFROMFILE);

                bmp.DeleteObject();
                bmp.Attach(hBitmap);
                bmp.GetObject(sizeof(BITMAP), &bm);
                memDC.CreateCompatibleDC(pDC);
                pOldBmp =memDC.SelectObject(&bmp);
               
              
                int offH = rect.Height() - bm.bmHeight;
                int offW = rect.Width() - bm.bmWidth;
                if (offH>0)
                {
                    rect.top += offH / 2;
                    rect.bottom -= (offH - offH / 2);
                }
                if (offW>0)
                {
                    rect.left += offW / 2;
                    rect.right -= (offW - offW / 2);
                }
                //顯示
                pDC->StretchBlt(rect.left, rect.top, rect.Width(), rect.Height(), &memDC, 0, 0, \
                    bm.bmWidth, bm.bmHeight, SRCCOPY);
            
                //Clean
                memDC.SelectObject(pOldBmp);
                bmp.DeleteObject();

            }
        }
        //Clean
        memDC.DeleteDC();

做了一下位置調整一般般吧
