Question

WPF ToolBarPanel和ToolBarTray之间的确切区别是什么？

Answer 1

Here you are

The ToolBar uses a ToolBarPanel and a ToolBarOverflowPanel in its ControlTemplate. The ToolBarPanel is responsible for the layout of the items on the toolbar. The ToolBarOverflowPanel is responsible for the layout of the items that do not fit on the ToolBar. For an example of a ControlTemplate for a ToolBar, see
