[普通]CTreeCtrl

      在view类添加成员变量：

private:

       CTreeCtrl m_TreeCtrl;

       CImageListm_ImageList;

2.       在OnCreate消息里处理创建：

m_TreeCtrl.Create(WS_VISIBLE|TVS_DISABLEDRAGDROP|WS_CHILD|WS_BORDER|TVS_HASLINES|TVS_HASBUTTONS|TVS_SHOWSELALWAYS|TVS_EDITLABELS,CRect(0,0,200,400),this,1);

       m_TreeCtrl.SetTextColor(RGB(0,0,255));

        m_ImageList.Create(16,16,ILC_COLOR32|ILC_MASK,0,0);

       m_TreeCtrl.SetImageList(&m_ImageList,TVSIL_NORMAL);

       m_TreeCtrl.ModifyStyle(0L,TVS_HASLINES|TVS_LINESATROOT|TVS_HASBUTTONS);

       for(inti=0;i<10;i++)

              m_ImageList.Add(AfxGetApp()->LoadIcon(IDI_ICON1+i));

       CTreeCtrl*pTreeCtl=&m_TreeCtrl;

       HTREEITEMitem;

       pTreeCtl->DeleteAllItems();

       item=pTreeCtl->InsertItem("基本信息",0,0,TVI_ROOT);

       pTreeCtl->InsertItem("员¡À工¡è信?息¡é",1,1,item);

       pTreeCtl->InsertItem("固¨¬定¡§资Á¨º产¨²",2,2,item);

       pTreeCtl->InsertItem("企¨®业°¦Ì结¨¢构1",3,3,item);

       item=pTreeCtl->InsertItem("查¨¦询¡¥",4,4,TVI_ROOT);

       pTreeCtl->InsertItem("简¨°单Ì£¤查¨¦询¡¥",5,5,item);

       pTreeCtl->InsertItem("复¡ä合?查¨¦询¡¥",6,6,item);

       item=pTreeCtl->InsertItem("打䨰印®?",7,7,TVI_ROOT);

       pTreeCtl->InsertItem("打䨰印®?工¡è资Á¨º条¬?",8,8,item);

       pTreeCtl->InsertItem("打䨰印®?报À¡§表À¨ª",9,9,item);

       pTreeCtl->InsertItem("打䨰印®?查¨¦询¡¥结¨¢果?",9,9,item);

现在效果图已经出来的，下面来增加对它的操作。

1，  删除所有项

void CTreeTestView::OnTreeopreatorDeleteallitems()

{

       // TODO: 在¨²此ä?添¬¨ª加¨®命¨¹令¢?处ä|理¤¨ª程¨¬序¨°代䨲码?

       if(!m_TreeCtrl.DeleteAllItems())

       {

              MessageBox("failed to delete all items");

       }

}

2，  删除选定项

void CTreeTestView::OnTreeopreatorDeleteselecteditem()

{

       // TODO: 在¨²此ä?添¬¨ª加¨®命¨¹令¢?处ä|理¤¨ª程¨¬序¨°代䨲码?

       HTREEITEMhItem=m_TreeCtrl.GetSelectedItem();

       m_TreeCtrl.DeleteItem(hItem);

}

3，  获取选定项的文本

void CTreeTestView::OnTreeopreatorGetselectediteminfo()

{

       // TODO: 在¨²此ä?添¬¨ª加¨®命¨¹令¢?处ä|理¤¨ª程¨¬序¨°代䨲码?

       HTREEITEMhItem=m_TreeCtrl.GetSelectedItem();

       CString strText;

       strText=m_TreeCtrl.GetItemText(hItem);

       MessageBox(strText);

}

4，  编辑选定项

void CTreeTestView::OnTreeopreatorEditselecteditem()

{

       // TODO: 在¨²此ä?添¬¨ª加¨®命¨¹令¢?处ä|理¤¨ª程¨¬序¨°代䨲码?

       // Replace the text in the label edit control, if possible.

       m_TreeCtrl.ModifyStyle(NULL,TVS_EDITLABELS);//设¦¨¨置?树º¡Â形?控?件t的Ì?风¤?格?

       m_TreeCtrl.EditLabel(m_TreeCtrl.GetSelectedItem());//当Ì¡À前¡ã结¨¢点Ì?进?入¨?编À¨¤辑-状Á¡ä态¬?

}

这个消息有点特殊，同时要这样做：

1.       添加消息

afx_msg voidOnEndlabeleditTree1(NMHDR*pNMHDR,LRESULT*pResult);

2.       消息映射

ON_NOTIFY(TVN_ENDLABELEDIT,1,OnEndlabeleditTree1)

3.       实现消息

void CTreeTestView::OnEndlabeleditTree1(NMHDR*pNMHDR,LRESULT*pResult)

{

       TV_DISPINFO*pTVDispInfo=(TV_DISPINFO*)pNMHDR;

       // TODO: Add your control notification handler code here

       CStringstrText;

       m_TreeCtrl.GetEditControl()->GetWindowText(strText.GetBuffer(200),200);

       m_TreeCtrl.SetItemText(m_TreeCtrl.GetSelectedItem(),strText);//设¦¨¨置?编À¨¤辑-后¨®的Ì?文?本À?为a结¨¢点Ì?

       *pResult=0;

}

5，  插入新项

void CTreeTestView::OnTreeopreatorInsertitem()

{

       // TODO: 在¨²此ä?添¬¨ª加¨®命¨¹令¢?处ä|理¤¨ª程¨¬序¨°代䨲码?

       HTREEITEMitem;

       CTreeCtrl*pTreeCtrl=&m_TreeCtrl;

       item=pTreeCtrl->InsertItem("new item",rand()%10,rand()%10,TVI_ROOT);

       pTreeCtrl->InsertItem("new item",1,1,item);

}

6，  修改选定项的文本

void CTreeTestView::OnTreeopreatorDynamicchangeselectedtextcontent()

{

       // TODO: 在¨²此ä?添¬¨ª加¨®命¨¹令¢?处ä|理¤¨ª程¨¬序¨°代䨲码?

       HTREEITEMhItem=m_TreeCtrl.GetSelectedItem();

       CString strText="change item";

       m_TreeCtrl.SetItemText(hItem,strText);

}

7，  响应鼠标左键双击

要响应通知消息（OnNotify）:

1.       添加消息

2.      afx_msg void OnDblclkTree1(NMHDR*pNMHDR,LRESULT*pResult);

3.       消息映射

ON_NOTIFY(NM_DBLCLK,1,OnDblclkTree1)//这里的1是treectrl的ID

4.       消息实现

void CTreeTestView::OnDblclkTree1(NMHDR*pNMHDR,LRESULT*pResult)

{

       // TODO: Add your control notification handler code here

       HTREEITEMhItem =m_TreeCtrl.GetSelectedItem();

       CString strText;

       strText=m_TreeCtrl.GetItemText(hItem);

       MessageBox(strText);

       *pResult=0;

}
