I'm not completely sure what you want, but here's what I was thinking
class vtkMyExporter ..... {
the usual vtkSetGetStuff and all the write, update, etc
void SetMyNameString(const char *) // for a single dataset/actor
void SetMyNameStringList(const char **) // for a list of items
};
this gets wrapped by client server etc etc
In the GUI, you could query the name from the pqXXX stuff, I have a similar
snippet that does this
pqPipelineSource *source = *it;
std::string xmlName = source->getProxy()->GetXMLName();
now you want the name, not the XML name, so use that
but now you can
vtkSMPropertyHelper modified(source->getProxy(), "MyNameString");
modified.Set(xmlName.c_str()); // or something like that
then you need to push your string into the VTK class using something like
source->getProxy()->UpdateVTKObjects()
or UpdatePipeline (I forget the correct calls)
and because your custom SetMyNameString doesn't trigger a modified in the
pipeline, you can carry on with doing the write, but the exporter has the
string passed in from he GUI just before it writes. You can pass a string list
if you want and make sure the order matches the order of writes so the names
match.
Since I'm not certain what you're doing, this is a bit hand wavy, but you get
the idea
Not sure if this helps your exact use case ...

Thanks for your answers!
John,
where on the gui-side do I need to pass that string? Do I need to modify the
ParaView sources? Because I only want to write a plugin which should be
redistributable to colleagues which have only the ParaView binaries installed.
And your suggestion assumes that I only want to export one actor right? What I
want is to export all actors in one step.

It'd probably be easier to add a method to the vtk-exporter class which accepts
a string, and from the gui, pass the string in just before export - because you
can get it the proxy name from the gui end. Make sure the
SetProxyName(char*...) method doesn't call Modified. (ie don't use
SetStringMacro)

It's not possible, not from a simple exporter plugin.The exporter
lives entirely in the VTK world without any knowledge of proxies. A
unconventional approach would be explicitly make the exporter plugin
link agains the pqCore library, then you can access the
pqApplicationCore and other singletons (like ProxyManager) and get
information about what sources are present and what their names are
(this is acceptable since exporter work entirely on the client-side).
It is still, however, non trivial to determine which actor corresponds
to what source proxy.

Dear ParaView users,
is it possible to programmatically get the name of an object in the Pipeline
Browser? To be more specific I need to get this name from a vtkActor. I am
writing a exporter plugin
(see http://www.mail-archive.com/[email protected]/msg12939.html) and
want to name my objects in the exported file.
Thanks for your help,
Lars.
