type=toolbox layout elements

append_tools, insert_tools, remove_tool, and remove_tools

This is equivalent to invoking the corresponding x::w::toolboxlayoutmanager method to modify the contents of the toolbox container.

<layout id="tools" type="toolbox">
  <append_tools>
    <name>initial-tools</name>
  </append_tools>
</layout>

append_tools and insert_tools have a name value that specifies the id of a factory that generates the contents of the resulting x::w::toolboxfactory. The position element specifies the insertion position parameter (for insert_tools) or the removal positional parameter (for remove_tool and remove_tools). The count element specifies how many remove_tools starting at the position.
