認(rèn)識(shí)Windows公共控件庫(kù)的使用；

一 創(chuàng)建樹視圖

首先用如下代碼看一下，創(chuàng)建樹視圖控件是否成功返回句柄；

hTree = CreateWindow("SysTreeView32", NULL,?
?WS_CHILD | WS_BORDER |WS_VISIBLE | TVS_HASLINES | TVS_HASBUTTONS | TVS_LINESATROOT,
?10, 20, 200, 400, hwnd, NULL, NULL, NULL);
wsprintf(szBuffer, "0x%X",hTree);
MessageBox(NULL,szBuffer,TEXT("樹視圖句柄"),0);?

創(chuàng)建成功；但此時(shí)樹視圖是空的；只有一個(gè)框；

二 添加第一個(gè)結(jié)點(diǎn)

代碼；

? ? ? ? ? ? TvInsertItem.hParent = NULL;
?? ??? ??? ?TvInsertItem.hInsertAfter = TVI_LAST;
?? ??? ??? ?TvInsertItem.item.mask = TVIF_TEXT;
?? ??? ??? ?TvInsertItem.item.pszText = pStrText;?? ??? ?
?? ??? ??? ?//TVI_LAST：insert the item at the end of list
?? ??? ??? ?hitema=SendMessage(hTree, TVM_INSERTITEM, 0, (LPARAM)(&TvInsertItem));;
? 添加結(jié)點(diǎn)的操作為：

? ? 定義??TVINSERTSTRUCT 結(jié)構(gòu)體對(duì)象TvInsertItem，此結(jié)構(gòu)體代表一個(gè)結(jié)點(diǎn)；

? ? 為TvInsertItem賦值，.hParent是此結(jié)點(diǎn)的父，根結(jié)點(diǎn)填為NULL；

? ? 向樹視圖發(fā)送消息，第一個(gè)參數(shù)是樹視圖句柄，第四個(gè)參數(shù)是TvInsertItem結(jié)構(gòu)體地址并轉(zhuǎn)為L(zhǎng)PARAM類型；

? ? 創(chuàng)建成功返回的是此次創(chuàng)建的結(jié)點(diǎn)的句柄，為?HTREEITEM 類型；

效果如下；

工程；

三 添加更多結(jié)點(diǎn)

創(chuàng)建子結(jié)點(diǎn)，.hParent成員填為父結(jié)點(diǎn)句柄；如果再創(chuàng)建根結(jié)點(diǎn)，.hParent填為NULL；

效果如下；

碼：
