void PEXAccumulateState(
Display *display,
PEXRenderer renderer,
unsigned long count,
PEXElementRef *elements
)
None.
Invoke PEXAccumulateState to accumulate the pipeline state that would be in effect if a traversal were done to the element specified in the path.
If the renderer state is PEXRendering or PEXPicking, this function traverses to the structure element at the end of the list in elements and modifies only the pipeline state according to the output commands in that path. No primitives are rendered. The initial pipeline state is the one in effect at the time this function is invoked.
During the traversal, the offset member of the last entry in the renderer's current path is incremented by one for each structure element traversed, including those that have no effect on the pipeline state. No structure member of the current path is changed. No action beyond incrementing the current path offset is taken when Execute Structure, Conditional Execute Structure, or Conditional Return elements are traversed.
As with all paths, the non-leaf elements in the path must contain offsets that refer to structure referencing output commands. If the structure referenced by the leaf node is locked, then the offset must refer to element position 0 or a structure referencing output command.
If the renderer state is PEXIdle, then this function has no effect.
