自绘CListCtrl(II)

http://www.codeproject.com/listctrl/ctooltiplistctrl.asp

实现功能：鼠标在ListCtrl上滑动的时候，滑动到哪一行哪一行就高亮，有且仅有一条是高亮的。

如何实现下面两个功能：
1.当鼠标离开ListCtrl的时候，高亮行取消高亮。
2.更改高亮行的背景色，默认是蓝色的，客户想要其它的颜色。

.h文件

class CMyListCtrl : public CListCtrl
{
	DECLARE_DYNAMIC(CMyListCtrl)

public:
	CMyListCtrl();
	virtual ~CMyListCtrl();

	DECLARE_MESSAGE_MAP()

public:
	virtual void DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct);
	
};

//自绘CListCtrl类，重载虚函数DrawItem  

void CNewListCtrl::DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct)  
{  
	// TODO: Add your code to draw the specified item  
	ASSERT(lpDrawItemStruct->CtlType == ODT_LISTVIEW);  
	CDC dc;   
	dc.Attach(lpDrawItemStruct->hDC);  
	ASSERT(NULL != dc.GetSafeHdc());  
	// Save these value to restore them when done drawing.  
	COLORREF crOldTextColor = dc.GetTextColor();  
	COLORREF crOldBkColor = dc.GetBkColor();  
	 
	// If this item is selected, set the background color   
	// and the text color to appropriate values. Also, erase  
	// rect by filling it with the background color.  
	if ((lpDrawItemStruct->itemAction | ODA_SELECT) && (lpDrawItemStruct->itemState & ODS_SELECTED))  
	{  
		dc.SetTextColor(::GetSysColor(COLOR_HIGHLIGHTTEXT));  
		dc.SetBkColor(::GetSysColor(COLOR_HIGHLIGHT));  
		dc.FillSolidRect(&lpDrawItemStruct->rcItem,   
		 ::GetSysColor(COLOR_HIGHLIGHT));  
	}  
	else  
	{  
		if(lpDrawItemStruct->itemID%2)  
			dc.FillSolidRect(&lpDrawItemStruct->rcItem, RGB(128,128,128));  
		else  
			dc.FillSolidRect(&lpDrawItemStruct->rcItem, RGB(255,128,255));  
	}  
	 
	// If this item has the focus, draw a red frame around the  
	// item's rect.  
	if ((lpDrawItemStruct->itemAction | ODA_FOCUS) &&	(lpDrawItemStruct->itemState & ODS_FOCUS))  
	{  
		CBrush br(RGB(0, 0, 128));  
		dc.FrameRect(&lpDrawItemStruct->rcItem, &br);  
	}  
	
	// Draw the text.  
	CString strText(_T(""));  
	CRect rcItem;  
	
	for(int i=0; i<GetHeaderCtrl()->GetItemCount(); i++)  
	{  
		strText = GetItemText(lpDrawItemStruct->itemID, i);  
		GetSubItemRect(lpDrawItemStruct->itemID, i, LVIR_LABEL, rcItem);  
		rcItem.left += 5;  
		dc.DrawText(  
		 strText,  
		 strText.GetLength(),  
		 &rcItem,  
		DT_LEFT|DT_SINGLELINE|DT_VCENTER);  
	}  
	 
	// Reset the background color and the text color back to their  
	// original values.  
	dc.SetTextColor(crOldTextColor);  
	dc.SetBkColor(crOldBkColor);  
	 
	dc.Detach();  
}  

// 调用  

CNewListCtrl m_list; // 类的成员变量  

 

#define IDC_LIST 0x1101  
m_list.Create(WS_CHILD|WS_VISIBLE|WS_BORDER|WS_VSCROLL|WS_HSCROLL|LVS_OWNERDRAWFIXED, CRect(0, 0, 280, 280), this, IDC_LIST);  
m_list.ModifyStyle(0, LVS_REPORT|LVS_SINGLESEL);  
m_list.SetExtendedStyle(LVS_EX_FULLROWSELECT | LVS_EX_GRIDLINES);  
m_list.InsertColumn(0, _T("AAA"), LVCFMT_LEFT, 100);  
m_list.InsertColumn(1, _T("BBB"), LVCFMT_LEFT, 100);  

CString strText(_T(""));  
for(int i=0; i<20; i++)  
{  
	m_list.InsertItem(i, _T(""));  
	strText.Format(_T("%d - Hello, World!"), i+1);  
	m_list.SetItemText(i, 0, strText);  
	strText.Format(_T("%d - ABCDEFG"), i+1);  
	m_list.SetItemText(i, 1, strText);  
}  

显示效果如下图所示：
