VS之treeview使用

2016年02月24日 ⁄ 综合 ⁄ 共 11573字 ⁄ 字号 小 中 大 ⁄ 评论关闭

本文简单地介绍下VS的treeview使用：包括属性设置、单击事件、双击事件、右键弹出菜单等。

使用工具：VS2008

使用语言：C++

开发步骤：

1.新建单文档程序，View派生于TreeView

2.添加图片资源，用于每一项文字前的图标

3.添加菜单资源，用于右键弹出

  

4.设置属性

void CTreeViewDemoView::OnInitialUpdate()
{
	CTreeView::OnInitialUpdate();

	//属性
	CTreeCtrl& tree = GetTreeCtrl();
	DWORD dwStyle = GetWindowLong(tree,GWL_STYLE);
	dwStyle |= TVS_HASBUTTONS | TVS_HASLINES | TVS_LINESATROOT | TVS_SHOWSELALWAYS;
	SetWindowLong(tree,GWL_STYLE,dwStyle);

	//菜单
	m_menu.LoadMenu(IDR_MENU1);
	tree.SetMenu(&m_menu);

	//图标
	m_ImageList.Create(IDB_BITMAP1,10,10,RGB(255,255,255));
	tree.SetImageList(&m_ImageList,LVSIL_NORMAL);

	//字体
	CFont font;
	font.CreateFont(
		15,
		0,
		0,
		0,
		FW_NORMAL,
		FALSE,
		FALSE,
		0,
		ANSI_CHARSET,
		OUT_DEFAULT_PRECIS,
		CLIP_DEFAULT_PRECIS,
		DEFAULT_QUALITY,
		DEFAULT_PITCH | FF_SWISS,
		_T("宋体"));
	tree.SetFont(&font);

	//更新界面
	UpdateTree();
}







5.更新数据


void CTreeViewDemoView::UpdateTree(void)
{
	CTreeCtrl& tree = GetTreeCtrl();
	tree.DeleteAllItems();

	CString str = _T("");
	int i=0, cnt = 0;
	HTREEITEM root,sub;

	str = _T("View1");
	root = tree.InsertItem(str,0,0,TVI_ROOT);
	tree.SetItemData(root,VIEW1_ROOT);
	m_TreeItem1 = root;

	cnt = 2;
	for(i=0; i<cnt; i++)
	{
		str.Format(_T("View1 %d"),i);
		sub = tree.InsertItem(str,1,1,m_TreeItem1);
		tree.SetItemData(sub,VIEW1_SUB);
	}
	tree.Expand(m_TreeItem1,TVE_EXPAND);

	str = _T("View2");
	root = tree.InsertItem(str,2,2,TVI_ROOT);
	tree.SetItemData(root,VIEW2_ROOT);
	m_TreeItem2 = root;

	cnt = 3;
	for(i=0; i<cnt; i++)
	{
		str.Format(_T("View2 %d"),i);
		sub = tree.InsertItem(str,3,3,m_TreeItem2);
		tree.SetItemData(sub,VIEW2_SUB);
	}
	tree.Expand(m_TreeItem2,TVE_EXPAND);
}










6.单击事件




void CTreeViewDemoView::OnNMClick(NMHDR *pNMHDR, LRESULT *pResult)
{
	// TODO: 在此添加控件通知处理程序代码
	CTreeCtrl& tree = GetTreeCtrl();
	CPoint CursorPoint;
	if(!GetCursorPos(&CursorPoint))
	{
		return;
	}
	tree.ScreenToClient(&CursorPoint);
	UINT uFlag=0;
	HTREEITEM select_item = tree.HitTest(CursorPoint,&uFlag);
	if((NULL != select_item) && (TVHT_ONITEM&uFlag))
	{
		tree.Select(select_item,TVGN_CARET);
	}
	else
	{
		return;
	}

	ShowView(select_item);

	*pResult = 0;
}

void CTreeViewDemoView::ShowView(HTREEITEM select_item)
{
	CTreeCtrl& tree = GetTreeCtrl();
	DWORD dwData = tree.GetItemData(select_item);
	CString sText = tree.GetItemText(select_item);
	CString str = _T("");

	switch(dwData)
	{
	case VIEW1_ROOT:
		str = _T("您点击了：") + sText;
		AfxMessageBox(str);
		break;
	case VIEW1_SUB:
		str = _T("您点击了：") + sText;
		AfxMessageBox(str);
		break;
	case VIEW2_ROOT:
		str = _T("您点击了：") + sText;
		AfxMessageBox(str);
		break;
	case VIEW2_SUB:
		str = _T("您点击了：") + sText;
		AfxMessageBox(str);
		break;
	default:
		break;
	}
}



 



7.双击事件




void CTreeViewDemoView::OnNMDblclk(NMHDR *pNMHDR, LRESULT *pResult)
{
	// TODO: 在此添加控件通知处理程序代码
	CTreeCtrl& tree = GetTreeCtrl();
	CPoint CursorPoint;
	if(!GetCursorPos(&CursorPoint))
	{
		return;
	}
	tree.ScreenToClient(&CursorPoint);
	UINT uFlag=0;
	HTREEITEM select_item = tree.HitTest(CursorPoint,&uFlag);
	if((NULL != select_item) && (TVHT_ONITEM&uFlag))
	{
		tree.Select(select_item,TVGN_CARET);
	}
	else
	{
		return;
	}

	ShowDlg(select_item);

	*pResult = 0;
}

void CTreeViewDemoView::ShowDlg(HTREEITEM select_item)
{
	CTreeCtrl& tree = GetTreeCtrl();
	DWORD dwData = tree.GetItemData(select_item);
	CString sText = tree.GetItemText(select_item);
	CString str = _T("");

	switch(dwData)
	{
	case VIEW1_ROOT:
		str = _T("您双击了双击了：") + sText;
		AfxMessageBox(str);
		break;
	case VIEW1_SUB:
		str = _T("您双击了双击了：") + sText;
		AfxMessageBox(str);
		break;
	case VIEW2_ROOT:
		str = _T("您双击了双击了：") + sText;
		AfxMessageBox(str);
		break;
	case VIEW2_SUB:
		str = _T("您双击了双击了：") + sText;
		AfxMessageBox(str);
		break;
	default:
		break;
	}
}




 


8.右击事件




void CTreeViewDemoView::OnNMRClick(NMHDR *pNMHDR, LRESULT *pResult)
{
	// TODO: 在此添加控件通知处理程序代码
	CTreeCtrl& tree = GetTreeCtrl();
	CPoint CursorPoint;
	if(!GetCursorPos(&CursorPoint))
	{
		return;
	}
	tree.ScreenToClient(&CursorPoint);
	UINT uFlag=0;
	HTREEITEM select_item = tree.HitTest(CursorPoint,&uFlag);
	if((NULL != select_item) && (TVHT_ONITEM&uFlag))
	{
		tree.Select(select_item,TVGN_CARET);
	}
	else
	{
		return;
	}

	ShowMenu(select_item);

	*pResult = 0;
}

void CTreeViewDemoView::ShowMenu(HTREEITEM select_item)
{
	CTreeCtrl& tree = GetTreeCtrl();
	DWORD dwData = tree.GetItemData(select_item);
	CString sText = tree.GetItemText(select_item);
	CMenu* pSubMenu = NULL;

	switch(dwData)
	{
	case VIEW1_ROOT:
		pSubMenu = m_menu.GetSubMenu(0);
		break;
	case VIEW1_SUB:
		pSubMenu = m_menu.GetSubMenu(0);
		break;
	case VIEW2_ROOT:
		pSubMenu = m_menu.GetSubMenu(1);
		break;
	case VIEW2_SUB:
		pSubMenu = m_menu.GetSubMenu(1);
		break;
	default:
		break;
	}

	if(pSubMenu)
	{
		CPoint CurSorPoint;
		GetCursorPos(&CurSorPoint);
		pSubMenu->TrackPopupMenu(TPM_LEFTALIGN,CurSorPoint.x,CurSorPoint.y,this);
	}
}

void CTreeViewDemoView::OnTest11()
{
	// TODO: 在此添加命令处理程序代码
	CString str = _T("菜单第一项第一个");
	AfxMessageBox(str);
}

void CTreeViewDemoView::OnTest12()
{
	// TODO: 在此添加命令处理程序代码
	CString str = _T("菜单第一项第二个");
	AfxMessageBox(str);
}

void CTreeViewDemoView::OnTest21()
{
	// TODO: 在此添加命令处理程序代码
	CString str = _T("菜单第二项第一个");
	AfxMessageBox(str);
}

void CTreeViewDemoView::OnTest22()
{
	// TODO: 在此添加命令处理程序代码
	CString str = _T("菜单第二项第二个");
	AfxMessageBox(str);
}

好了，关于VS的treeview使用就到这了。
