MatAssignData* test = (MatAssignData* ) bcMat.GetCustomDataType( ID_MATERIALASSIGNMENTS, CUSTOMDATATYPE_MATASSIGN );
......ok....but now I need to call test->BuildInclusionTablem which returns a MatAssignTable...but MatAssignTable* leads to a linker error.......

Hi,
I have the same problem. :( When I try to build my plugin the compiler tells me:
error LNK2001: unresolved external symbol "public: class MatAssignTable * __thiscall MatAssignData::BuildInclusionTable(class BaseDocument *,long)" (?BuildInclusionTable@MatAssignData@@QAEPAVMatAssignTable@@PAVBaseDocument@@J@Z)
fatal error LNK1120: 1 unresolved externals
I don´t know why. I have included the customgui_matassign.h and my code is correct too (it compiles without problems)
Any idea what the problem may be?
Thanks!

Hmm, no. It seems to work here. What compiler do you use?

I never got BuildInclusionTable to run, I use the ObjectFromIndex function to get access to the assign data.

Hey Guys,
I need to access all of the elements found within the Assignment page of a given material. Now, I found the matAssignData class which is exactly what I am looking for. The problem is that when ever I call the GetTheCustomDataType() it ALWAYS returns NULL! Here is the code:
if(!replaceMaterial || !withMaterial) return TRUE;
BaseContainer *rmBC = replaceMaterial->GetDataInstance();
MatAssignData *replaceAssignData = (MatAssignData* )rmBC->GetCustomDataType(ID_MATERIALASSIGNMENTS, CUSTOMDATATYPE_MATASSIGN);
if(!replaceAssignData)
{
GePrint("MatAssignData is NULL!");
return TRUE;
}
As always thanks in advance for any help.

Here a little example how to access the MatAssigData.
BaseMaterial *mat = doc->GetActiveMaterial();
if(!mat) return TRUE;
GeData d;
if(mat->GetParameter(DescLevel(ID_MATERIALASSIGNMENTS),d,0))
{
MatAssignData *mad = (MatAssignData* )d.GetCustomDataType(CUSTOMDATATYPE_MATASSIGN);
if(mad) GePrint("found it");
GePrint(LongToString(mad->GetObjectCount())+" objects");
}
hope this helps
cheers,
Matthias

Yes that should work, is also the way we use it.
Be careful, every time you make the get on it, the assign list of the material will be updated. We noticed that this takes a longer while if the material is assigned to many objects. Seems to me, that the assign list itself has a non optimal implementation, like if adding an entry to the list takes O(n²), n the number of entries which are already in the list. It does not seem to depend on the size of the object tree, that has to be parsed for filling the assign list, but that seems to be fast, a material used only in several objects but with a very huge object tree is still fast.
