1.如何在TreeList中加图标?

  [问题提出]

  请问treeview控件和treectrl控件的用法有何不同呢？向如何imagelist控件中加图象呀？

  [解决方法]

  1)

    HICON hicon[8];

    m_imageList.Create(16,16,0,8,8);

    hicon[0]=AfxGetApp()->LoadIcon(IDI_ICON0);

    hicon[1]=AfxGetApp()->LoadIcon(IDI_ICON1);

    hicon[2]=AfxGetApp()->LoadIcon(IDI_ICON2);

    hicon[3]=AfxGetApp()->LoadIcon(IDI_ICON3);

    hicon[4]=AfxGetApp()->LoadIcon(IDI_ICON4);

    hicon[5]=AfxGetApp()->LoadIcon(IDI_ICON5);

    hicon[6]=AfxGetApp()->LoadIcon(IDI_ICON6);

    hicon[7]=AfxGetApp()->LoadIcon(IDI_ICON7);

    for(int n=0;n<8;n++)

        m_imageList.Add(hicon[n]);

    CTreeCtrl *pTree=(CTreeCtrl *)GetDlgItem(IDC_TREE);

    pTree->SetImageList(&m_imageList,TVSIL_NORMAL);

  2)

    CImageList cil1;

    cil1.Create(32,32,TRUE,2,2);

    cil1.Add(pApp->LoadIcon(IDI_DAO1));

    cil1.Add(pApp->LoadIcon(IDI_DAO2));

    cil1.Add(pApp->LoadIcon(IDI_DAO3));

    cil1.Add(pApp->LoadIcon(IDI_DAO4));

    cil1.Add(pApp->LoadIcon(IDI_DAO5));

    cil1.Add(pApp->LoadIcon(IDI_DAO6));

    cil1.Add(pApp->LoadIcon(IDI_DAO7));

    cil1.Add(pApp->LoadIcon(IDI_DAO8));

    cil1.Add(pApp->LoadIcon(IDI_DAO9));

    

    //设置图象列表

    m_list.SetImageList(&cil1,LVSIL_NORMAL);

 

2.如何选择CTreeCtrl中的节点文本进行编辑?

在向CTreeCtrl中加入一项后,有什么方法可以编辑该节点的文本呢?

首先设置你的CcompTreeCtrl具有TVS_EDITLABELS属性.在设计时用控件属性来设置在运行时用GetStyle()/SetStyle()成员函数来设置.然后请看下述代码:

HTREEITEM CCompTreeCtrl::AddSet()

{

static int setCnt =3D 1;

HTREEITEM hItem;

CString csSet;

//create text for new note: New Set 1, New Set 2 ...

csSet.Format( _T( "New Set %d" ), setCnt++ );

hItem =3D InsertItem( csSet, IMG_CLOSEDFOLDER, IMG_CLOSEDFOLDER );

if( hItem !=3D NULL )

           EditLabel( hItem );

return hItem;

}
