spTree (Shape Tree)
This element specifies all shape-based objects, either grouped or not, that can be referenced on a given slide. As most objects within a slide are shapes, this represents the majority of content within a slide. Text and effects are attached to shapes that are contained within the spTree element.
[Example: Consider the following PresentationML slide
<p:sld> <p:cSld> <p:spTree> <p:nvGrpSpPr> … </p:nvGrpSpPr> <p:grpSpPr> … </p:grpSpPr> <p:sp> … </p:sp> </p:spTree> </p:cSld> … </p:sld>
In the above example the shape tree specifies all the shape properties for this slide. end example]
Each shape-based object within the shape tree, whether grouped or not, shall represent one unique level of z-ordering on the slide. The z-order for each shape-based object shall be determined by the lexical ordering of each shape-based object within the shape tree: the first shape-based object shall have the lowest z-order, while the last shape-based object shall have the highest z-order.
The z-ordering of shape-based objects within the shape tree shall also determine the navigation (tab) order of the shape-based objects: the shape-based object with the lowest z-order (the first shape in lexical order) shall be first in navigation order, with objects being navigated in ascending z-order.
[Example: Consider the following PresentationML slide with two shapes
<p:sld> <p:cSld> <p:spTree> … <p:sp> <p:nvSpPr> <p:cNvPr id="5" name="Oval 4" /> … </p:nvSpPr> … </p:sp> <p:sp> <p:nvSpPr> <p:cNvPr id="4" name="Isosceles Triangle 3" /> … </p:nvSpPr> … </p:sp> </p:spTree> </p:cSld> … </p:sld>
In the above example the shape with name Oval 4 has the lowest z-order value since that shape is the first shape in the shape tree. Oval 4 is also the first shape in navigation order. The shape with name Isosceles Triangle 3 has the highest z positioning value since that shape is the last shape in the shape tree. Isosceles Triangle 3 is also the last shape in navigation order. end example]
