本文探讨了在Windows应用程序中浮动工具栏与停靠工具栏的不同之处。浮动工具栏作为迷你框架窗口的一部分，而停靠工具栏则是框架窗口的子窗口。这两种类型的工具栏在其所有者和生命周期管理方面存在差异。

A docked toolbar is a child of the frame window it's docked to, but a floating toolbar is a child of the mini frame window that surrounds it. The mini frame window is a popup window owned by the frame window, but it's not a child of the frame window. (A popup window is a window with the style WS_POPUP; a child window has the WS_CHILD style instead.) The distinction is important because popup windows owned by a frame window are destroyed before the frame window is destroyed. Child windows, on the other hand, are destroyed after their parents are destroyed. A floating toolbar no longer exists when the frame window's OnDestroy function is called.
