Hi Matthew,
that you do not get child elements is odd, could you send me a working
basic code snipped that
iterates over the root element? Than I could do a quick debug session to
see whats wrong.
Regards,
Christian

Hello Matthew,

Animation nodes are organized as a tree whose root node can be obtained from
each DrawPage. See com::sun::star::animations for documentation of the
interfaces. The XAnimationNode::Type specifies the type of each node.
Inner nodes with children have type AnimationNodeType::PAR (parallel
execution of the child animations) or AnimationNodeType::SEQ (sequential
execution). Inner nodes implement css::container::XEnumerationAccess to
provide access to their children.
The nodes that start an animation sequence (triggered for example by
pressing the space bar) can be found by looking at the XAnimationNode::BEGIN
attribute. Their css::animations::Event objects have a Trigger attribute of
value css::animations::EventTrigger::ON_NEXT.

You seem to be describing the C++ API and it doesn't seem to
correspond fully with the StarBasic API. I'm trying to inspect things
with the Xray tool, so most of what I have found out has been through
playing with that tool:
-I can get at the root animation node via the AnimationNode property
of the DrawPage for each slide. This object is a
ParallelTimeContainer, which I assume means it has something like
AnimationNodeType::PAR, but I can't find that exactly. What I do find
is a property called "UserData" which contains a NamedValue with name
"node-type" that contains an integer which seems to be the
AnimationNodeType you refer to (for the root node, it is equal to
com.sun.star.presentation.EffectNodeType.TIMING_ROOT in StarBasic).
-When I look at the "Begin" property of the root animation node, Xray
gives me an error indicating that this value does not exist in this
context. I see no way to get at any css::animations::Event objects.
-Finally, when I try to iterate over the children by calling
.createEnumeration() on the node and then using a for loop with
.hasMoreElements(), etc., I find no elements. This is definitely the
root animation node on a draw page _with_ animations.
Any help here would be appreciated. Do I need to create some new
context-dependent object based on the node for a new interface? Is
there any way to figure out the correspondence between Basic API and
C++ API by looking at sources (that is, does the C++ API get exposed
in StarBasic in some predictable way, or are the Basic objects coded
separately as custom wrappers of the various C++ classes)?
Sorry for the very basic questions, but right now I just don't feel
like I have enough knowledge of UNO, StarBasic, etc. to really figure
out this API.
Thanks,
Matthew
