如何让ListCtrl控件失去焦点后还高亮，据说需要重绘，但遇到问题

[yeaiping]

我派生了CListCtrl类，ClistCtrlEx，然后在它里面使用如下：
afx_msg void OnCustomDraw(NMHDR*,LRESULT*);
....
//消息映射
ON_NOTIFY_REFLECT(NM_CUSTIOMDRAW,OnCUstomDraw)
....

//函数
void CListCtrlEx::OnCustonDraw(NMHDR* pNMHDR,LRESULT* pResult)
{
LPNMLVCUSTOMDRAW lpLvcd=(LPNMLVCUSTOMDRAW)pNMHDR;
switch(lpLvcd->nmcd.dwDrawStage)
{
case CDDS_PREPAINT:
*pResult=CDRF_NOTIFYITEMDRAW;
break;
case CDDS_ITEMPREPAINT:
**pResult=CDRF_NOTIFYITEMDRAW;
break;
case CDDS_ITEMPREPAINT | CDDS_SUBITEM:
//在这里重绘
//如何判断是对选中的Item进行重绘，我不会
。。。。。。。。。。
lpLvcd->clrText=RGB(0,0,0);// 黑色字体
lpLvcd->clrTextBk=RGB(0,0,255);//蓝色背景
*pResult=CDRF_DODEFULT;
break;
default:
*pResult=CDRF_DODEFULT;
break;
}
}
然后在主函数中定义： CListCtrlEx m_ctrlList;

以上代码都是网上找的，确实可以重绘，但是没有写如何重绘，重绘失去焦点的项目。
我猜应该是在失去焦点的事件中重绘，然后再判断是哪个选中了。上面的是把所有所有项都重绘了。

这个是选中你要选的高亮，如果想改成你选中的高亮，要改一下判断项！

[fandh]

CString strTemp = m_ctListCtrl.GetItemText(nItem,pLVCD->iSubItem);
CString str = m_ctListCtrl.GetItemText(nItem,3);

if(strTemp == m_strName)


改成：
BOOL bSelect = FALSE;
POSITION pos = m_ctListCtrl.GetFirstSelectedItemPosition();
while(pos)
{
int index = m_ctListCtrl.GetNextSelectedItem(pos);
if(index==nItem)
{
bSelect = TRUE;
break;
}
}

if(bSelect)

你说的没错，我太笨了。不会举一反三，我不知道怎么样得到当选中ClistCtrl项后，我要把焦点移开，鼠标点别的地方去的时候，还能让之前选中项高亮，但是怎么样判断我不会

[fandh]

我上面已经有代码了！你按照那个改动一下，至于里面的颜色，你自己修改成你想要的颜色！

很感谢你，不过你的代码好像是不对，没成功

[yeaiping]

int nItem = static_cast<int>( pLVCD->nmcd.dwItemSpec );
这条语句能得到什么，是选中项的号吗？
BOOL bSelect = FALSE;
POSITION pos =m_ctrlListName.GetFirstSelectedItemPosition();
while(pos)
{
int index = m_ctrlListName.GetNextSelectedItem(pos);
if(index==nItem)
{
bSelect = TRUE;
break;
}
}
这段代码是得到选中的Item号

[fandh]

呵呵，我这边已经通过运行了！

[fandh]

是的，然后，将下面的if语句改成：if(bSelect)
说明是选中的！以前的那个if语句不要了！

是判断当前是否选中的！

是吗，你真的通过了，我这边怎么点和以前一样呢，我是想这么实现，先选中（选中项肯定高亮），然后鼠标点击Edit控件，这样Clistctrl就失去焦点了，然后还需要把刚开始选中项高亮，谢谢你，能否把你调试通过的代码贴下来，谢谢。分都给你了

你那边出什么错误？

[yeaiping]

希望你能帮我调一下，真郁闷，其实就是想把界面做漂亮一点，其他功能已经实现

[fandh]

你要不，将我的代码发到我的MAIL里面：[e-mail]

我的程序有一大部分是操作硬件的，访问驱动程序的，呵呵，而这个部分只是里面的一个小功能。要不你把你调通的项目工程发给我，我看看，因为，我对照了你的代码，发现我的就是粘贴你的，但是就是出不来。我的邮箱：[e-mail]或者[e-mail]。可以加我好友，我是学硬件，所以对编程不是很懂

[fandh]

已经发给你了！

我明白了，原来我设置了show selection always这个项，把它
LONG lStyle;
lStyle= GetWindowLong(m_ctrlListName.m_hWnd, GWL_STYLE); // 获取当前窗口style
lStyle&=~LVS_SHOWSELALWAYS; // 清除显示方式位
SetWindowLong(m_ctrlListName.m_hWnd, GWL_STYLE, lStyle); // 设置style
去掉就OK了，
谢谢你了，散分了

终于找到原因了，谢谢楼主分享解决方案。同样的问题，折磨我大半天。原来是创建时候问题
