关于CTreeCtrl控件

愤怒的豆沙包 2012-02-15 09:49:07

最近在学习OCX控件，想做一个仅仅显示一个TreeView控件，内容设置好了，该怎么设置去显示它呢？





int CAa_testCtrl::OnCreate(LPCREATESTRUCT lpCreateStruct) 

{

	if (COleControl::OnCreate(lpCreateStruct) == -1)

		return -1;



	m_treeDlog = new treeDlog();

	//Check if new succeeded and we got a valid pointer to a dialog object

	if(m_treeDlog != NULL)

	{

		BOOL ret = m_treeDlog->Create(IDD_FORMVIEW,this);

		if(!ret)   //Create failed.

			AfxMessageBox(_T("Error creating Dialog"));

		m_treeDlog->ShowWindow(SW_SHOW);

	}

	else

		AfxMessageBox(_T("Error Creating Dialog Object"));

	



	//m_treeDlog.ShowCaret();



	TV_INSERTSTRUCT tvinsert;

	tvinsert.hParent=NULL;

	tvinsert.hInsertAfter=TVI_LAST;

	tvinsert.item.mask=TVIF_IMAGE|TVIF_SELECTEDIMAGE|TVIF_TEXT|TVIF_STATE;

	tvinsert.item.hItem=NULL;

	tvinsert.item.state=INDEXTOSTATEIMAGEMASK( 1 );

	tvinsert.item.stateMask=TVIS_STATEIMAGEMASK;

	tvinsert.item.cchTextMax=6;

	tvinsert.item.iSelectedImage=1;

	tvinsert.item.cChildren=0;

	tvinsert.item.lParam=0;



	tvinsert.item.pszText = (unsigned short*)"dfdf";

	tvinsert.item.iImage=0;

	HTREEITEM hRoot=m_treeCtrl.InsertItem(&tvinsert);



	m_treeCtrl.SetItemState( hRoot, INDEXTOSTATEIMAGEMASK(0), TVIS_STATEIMAGEMASK , true);



	//second level

	tvinsert.hParent=hRoot;

	tvinsert.item.iImage=0;

	tvinsert.item.pszText=(unsigned short*)"江苏省";

	m_treeCtrl.InsertItem(&tvinsert);

	

	tvinsert.hParent=hRoot;

	tvinsert.item.pszText=(unsigned short*)"湖北省";

	HTREEITEM h1=m_treeCtrl.InsertItem(&tvinsert);

	

	tvinsert.hParent=hRoot;

	tvinsert.item.pszText=(unsigned short*)"广东省";

	m_treeCtrl.InsertItem(&tvinsert);

	

	tvinsert.hParent=h1;

	tvinsert.item.pszText=(unsigned short*)"武汉市";

	m_treeCtrl.InsertItem(&tvinsert);

	



	AfxMessageBox( (LPCTSTR)"InsertItem", MB_OK, 0);



	m_treeCtrl.ShowWindow(SW_SHOW);

	return 0;

}
