相关代码如下：
BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext)
{
if (!m_wndSplitter.CreateStatic(this, 1, 2))
{
return FALSE;
}
CRect rect;
GetClientRect(&rect);
m_wndSplitter.CreateView(0, 0, RUNTIME_CLASS(TreeView), CSize(rect.Width() / 3 - 170, rect.Height()), pContext);
if (!m_wndSplitter2.CreateStatic(&m_wndSplitter, 1, 2, WS_CHILD | WS_VISIBLE, m_wndSplitter.IdFromRowCol(0, 1))
|| !m_wndSplitter2.CreateView(0, 0, RUNTIME_CLASS(EditView), CSize(rect.Width() / 3 - 50, rect.Height()), pContext)
|| !m_wndSplitter2.CreateView(0, 1, RUNTIME_CLASS(EditView), CSize(rect.Width() / 3, rect.Height()), pContext))
{
return FALSE;
}
return TRUE;
//return CFrameWnd::OnCreateClient(lpcs, pContext);
}
void TreeView::OnInitialUpdate()
{
CTreeView::OnInitialUpdate();
ptheTree = &GetTreeCtrl();
ptheTree->ModifyStyle(0, TVS_HASLINES | TVS_EDITLABELS | TVS_HASBUTTONS | TVS_EDITLABELS | TVS_LINESATROOT);
TVINSERTSTRUCT tvInsert;
HTREEITEM hTreeItem;
tvInsert.hInsertAfter = TVI_LAST;//TVI_LAST;
tvInsert.hParent = TVI_ROOT;
tvInsert.item.mask = TVIF_TEXT;
tvInsert.item.pszText = "搜索引擎";
hTreeItem = ptheTree->InsertItem(&tvInsert);
tvInsert.hParent = hTreeItem;
tvInsert.item.pszText = "Google";
ptheTree->InsertItem(&tvInsert);
tvInsert.item.pszText = "Baidu";
ptheTree->InsertItem(&tvInsert);
ptheTree->Expand(hTreeItem, TVE_EXPAND); //默认为合上的TVE_COLLAPSE,打开的TVE_EXPAND
}
做出来后效果这样
但是当我点根项时并没有展开（况且我类型设置了TVE_EXPAND，应该直接是打开的啊。。），而且单击根项应该选中高亮的也没有（实际效果是高亮一下后立刻恢复了，就跟刷新了似得）。
大家帮我看看问题可能出在哪。。
