TreeView 控件使用例子

1. 介绍两个个结构：

a. 项目结构

typedef struct tagTVITEMW { UINT mask; HTREEITEM hItem; UINT state; UINT stateMask; LPWSTR pszText; int cchTextMax; int iImage; int iSelectedImage; int cChildren; LPARAM lParam;} TVITEMW, *LPTVITEMW;#define TVITEM TVITEMW#define TV_ITEM TVITEM

b. 插入结构

typedef struct tagTVINSERTSTRUCTW { HTREEITEM hParent; HTREEITEM hInsertAfter;#if (_WIN32_IE >= 0x0400) union { TVITEMEXW itemex; TV_ITEMW item; } DUMMYUNIONNAME;#else TV_ITEMW item;#endif} TVINSERTSTRUCTW, *LPTVINSERTSTRUCTW;#define TVINSERTSTRUCT TVINSERTSTRUCTW#define TV_INSERTSTRUCT TVINSERTSTRUCT

2. 使用例子

TV_ITEM item;item.mask = TVIF_TEXT | TVIF_PARAM;item.cchTextMax = 2;item.pszText = L"C: ";TV_INSERTSTRUCT insert;insert.hParent = TVI_ROOT;insert.hInsertAfter = TVI_LAST;insert.item = item;HTREEITEM hRoot1 = m_cTreeCtl.InsertItem(&insert);item.pszText = L"windows";item.cchTextMax = 7;insert.hParent = hRoot1;insert.item = item;m_cTreeCtl.InsertItem(&insert);

（具体说明后期会加入）
