请问如何在列表控件中画直线？

[mefish]

就好像Windows NT下的性能监视器的不同计数器的画线颜色在列表中有显示那样

可以参考

其他类似对可以见http://www.csdn.net/dev/visual%20c++/->source->ListView Control

我不是在为列表控件画格，而是列表项中画横线，请看http://go.163.com/lsye/question.jpg
谢谢！

创建位图,位图上画线，加载位图!

[mefish]

我试试看吧，我对位图的操作还是很害怕的

[prog_st]

那有什么害怕的！创建CImageList,关联到CListCtrl

[prog_st]

不过你的CImageList可得特殊创建

本人经过一番苦思冥想，找到了一个“瞒天过海”的办法，就是不用位图，而是用彩色文字，文字是制表符"───"，人们会以为这是一条横线。方法如下，供大家共享：
首先截获列表控件的“自画”消息，
BEGIN_MESSAGE_MAP(CSysMonitorClientView, CFormView)
ON_NOTIFY(NM_CUSTOMDRAW, IDC_PROCESS_LIST, OnCustomdrawList)
END_MESSAGE_MAP()
在头文件中定义函数
afx_msg ;
实现函数如下：
void OnCustomdrawList (NMHDR* pNMHDR, LRESULT* pResult)
{
//ysy:get the code fragment from
//ysy:http://www.codeproject.com/listctrl/lvcustomdraw.asp
NMLVCUSTOMDRAW* pLVCD = reinterpret_cast<NMLVCUSTOMDRAW*>( pNMHDR );

// Take the default processing unless we set this to something else below.
*pResult = CDRF_DODEFAULT;

// First thing - check the draw stage. If it's the control's prepaint
// stage, then tell Windows we want messages for every item.

if ( CDDS_PREPAINT == pLVCD->nmcd.dwDrawStage )
{
*pResult = CDRF_NOTIFYITEMDRAW;
}
else if ( CDDS_ITEMPREPAINT == pLVCD->nmcd.dwDrawStage )
{
// This is the notification message for an item. We'll request
// notifications before each subitem's prepaint stage.

*pResult = CDRF_NOTIFYSUBITEMDRAW;
}
else if ( (CDDS_ITEMPREPAINT | CDDS_SUBITEM) == pLVCD->nmcd.dwDrawStage )
{
// This is the prepaint stage for a subitem. Here's where we set the
// item's text and background colors. Our return value will tell
// Windows to draw the subitem itself, but it will use the new colors
// we set here.

COLORREF crText;

if ( 0 == pLVCD->iSubItem)
crText=RGB(255,0,0); //换成自己的颜色
else
crText = RGB(0,0,0);

// Store the colors back in the NMLVCUSTOMDRAW struct.
pLVCD->clrText = crText;

// Tell Windows to paint the control itself.
*pResult = CDRF_DODEFAULT;
}
}
