求一个图片按钮例子

Question

要工程源码，原理看多了，似乎没有满意的回答

Answer 1

void SetBkBmp(LPCSTR lpszBmp)
{
::lstrcpy(m_tcFileName,lpszBmp);

if (m_hBmpBK) 
{
DeleteObject(m_hBmpBK);
m_hBmpBK = NULL;
}
TCHAR szDisk[64]={0};
TCHAR szPath[512]={0};
TCHAR szName[_MAX_FNAME]={0};
TCHAR szExt[_MAX_EXT]={0};
_splitpath(lpszBmp,szDisk,szPath,szName,szExt);
if (lstrcmpi(szExt,".bmp") == 0)
{
m_hBmpBK = (HBITMAP)LoadImage(AfxGetInstanceHandle(), m_tcFileName, IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE|LR_DEFAULTSIZE|LR_CREATEDIBSECTION);
if (m_hBmpBK)
{
m_bBitmap = TRUE;
BITMAP bm = { 0 };
::GetObject(m_hBmpBK, sizeof(BITMAP), &bm);  
m_nWidth = bm.bmWidth;
m_nHeight = bm.bmHeight;
}
}
else 
{
m_hIcon = (HICON)LoadImage(NULL,m_tcFileName,IMAGE_ICON,0, 0, LR_LOADFROMFILE);
if (m_hIcon)
{
m_bBitmap = FALSE;
ICONINFO info = { 0 };
GetIconInfo(m_hIcon,&info);
BITMAP bp = { 0 };
GetObject((HGDIOBJ)info.hbmColor,sizeof(bp),&bp);
m_nWidth = bp.bmWidth*4;
m_nHeight = bp.bmHeight;
if (info.hbmColor)
::DeleteObject(info.hbmColor);
if (info.hbmMask)
::DeleteObject(info.hbmMask);
}


}

}

Answer 2

CBitmapButton...
现在的，
按钮的属性要设成OwnerDraw...CBitmapButton myButton;// Create the bitmap button (must include the BS_OWNERDRAW style).
myButton.Create(NULL, WS_CHILD|WS_VISIBLE|BS_OWNERDRAW, 
   CRect(10,10,100,100), pParentWnd, 1);// Load the bitmaps for this button.
myButton.LoadBitmaps(IDB_UP, IDB_DOWN, IDB_FOCUS, IDB_DISABLE);
