windows - MFC中如何在CTreeCtrl列表中添加图片

Question

我试图在 CTreeList 控件中的文本之前添加图像，但它没有出现，但我观察到节点名称在一些空间之后开始，就像它为位图留下空间一样，但图像不是显示..这是代码快照:-

CImageList m_ImageList;

CBitmap m_Bitmap1;

m_ImageList.Create(16,16,ILC_COLOR32,1,1);

m_Bitmap1.LoadBitmap(IDB_BITMAP1);

m_ImageList.Add(&m_Bitmap1, RGB(0,0,0));

TreeSoft->Create(WS_CHILD | WS_VISIBLE | WS_BORDER | WS_TABSTOP |
            TVS_HASLINES | TVS_HASBUTTONS | TVS_LINESATROOT |
            TVS_SINGLEEXPAND | TVS_SHOWSELALWAYS |  
            TVS_TRACKSELECT,
            CRect(10, 10, 200, 240), this, 0x1221);


    TreeSoft->SetImageList(&m_ImageList, TVSIL_NORMAL);

hTree = TreeSoft->InsertItem( L"Software Production",0,0, TVI_ROOT);

hCompany = TreeSoft->InsertItem(L"Microsoft",0,0, hTree);

请告诉我我在这里缺少什么...

现在你只需要为新创建的分支设置图像:

TreeSoft->SetItemImage(hTree , 0, 0); // I think it starts from 0 (if it does not show try 1)
