【ＳＤＫ】如何实现位图按钮啊？已经卡了一天半了。

Question

ＳＤＫ下位图按钮怎么做？就在按钮上贴个图片而已，其他特效暂不考虑。谁能给个例程我学习一下啊？

Answer 1

给你篇文章看

Answer 2

晕 要SDK下实现啊 
我用得MFC 
太激动了 呵呵

Answer 3

//可以参考一下CBitmapButton类。void CBitmapButton::DrawItem(LPDRAWITEMSTRUCT lpDIS)
{
ASSERT(lpDIS != NULL);
// must have at least the first bitmap loaded before calling DrawItem
ASSERT(m_bitmap.m_hObject != NULL);     // required // use the main bitmap for up, the selected bitmap for down
CBitmap* pBitmap = &m_bitmap;
UINT state = lpDIS->itemState;
if ((state & ODS_SELECTED) && m_bitmapSel.m_hObject != NULL)
pBitmap = &m_bitmapSel;
else if ((state & ODS_FOCUS) && m_bitmapFocus.m_hObject != NULL)
pBitmap = &m_bitmapFocus;   // third image for focused
else if ((state & ODS_DISABLED) && m_bitmapDisabled.m_hObject != NULL)
pBitmap = &m_bitmapDisabled;   // last image for disabled // draw the whole button
CDC* pDC = CDC::FromHandle(lpDIS->hDC);
CDC memDC;
memDC.CreateCompatibleDC(pDC);
CBitmap* pOld = memDC.SelectObject(pBitmap);
if (pOld == NULL)
return;     // destructors will clean up CRect rect;
rect.CopyRect(&lpDIS->rcItem);
pDC->BitBlt(rect.left, rect.top, rect.Width(), rect.Height(),
&memDC, 0, 0, SRCCOPY);
memDC.SelectObject(pOld);
}

Answer 4

为啥用SDK啊
如果不用MFC，可以用下WTL挺好的

Answer 6

没办法啊，我是新手，用SDK学的东西多一点。MFC的话我会，网上例子也多。我先学习下楼上各位的方法。

}为什么没有实现鼠标移动在按钮上图片变化的效果
