从Qt原生QDockWidget到QADS进阶：那些官方文档没告诉你的性能优化技巧本文深入探讨了从Qt原生QDockWidget切换到Qt Advanced Docking System (QADS)后的性能优化实战。针对复杂界面卡顿问题，文章剖析了QADS容器化设计与原生系统的渲染机制差异，并分享了透明分割器性能取舍、浮动窗口内存管理、嵌套布局优化等官方文档未提及的进阶技巧，帮助开发者在大型桌面应用中实现丝滑流畅的交互体验。阅读详情

rt.top = 0;
rt.bottom = 150;
rt.left = 20;
rt.right = 200;
DockControlBar(&m_DockBar1, AFX_IDW_DOCKBAR_LEFT, &rt);
rt.top = 150;
rt.bottom = 300;
DockControlBar(&m_DockBar2, AFX_IDW_DOCKBAR_LEFT, &rt);

return 0;
}
请大家帮忙看看，我想要的结果就是左边有两个竖排的浮动窗口，但是有时候却变成并列的两个？

BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext)
{
// CG: The following block was added by the Splitter Bar component.
{
// if (!m_wndSplitter.Create(this,
// 2, 1, // TODO: adjust the number of rows, columns
// CSize(10, 10), // TODO: adjust the minimum pane size
// pContext))
if(!m_wndSplitter.CreateStatic(this, 2, 1))
{
TRACE0("Failed to create splitter bar ");
return FALSE; // failed to create
}
CRect rt;
GetClientRect(&rt);
m_wndSplitter.CreateView(0, 0, RUNTIME_CLASS(CDockTestView), CSize(rt.Width(), rt.Height() / 2), pContext);
m_wndSplitter.CreateView(1, 0, RUNTIME_CLASS(CMyView), CSize(rt.Width(), rt.Height() / 2), pContext);

return TRUE;
}
}
右边的窗体想居中平均分割两个，但是却总是无法居中分割？
请大家帮忙，在线等待！解决马上给分，不够可以再给！谢谢！
