I'm setting up a dialog that uses the basic structure of 'ActiveObject.cpp' from the cinema4dsdk. But instead of just mirroring the Object Manager, I'd like to only show certain objects (that contain my plugin's tag).How would one go about this?
Should I be doing some checking/restricting in the TreeViewFunctions GetFirst(), GetNext(), GetPred(), GetDown() methods?
Thanks!

Well, trying something that seemed logical, was, hmm, logical.
void* GetFirst(void* root, void* userdata) { BaseDocument* doc = (BaseDocument* )root; return GetObject(doc->GetFirstObject()); } void* GetNext(void* root, void* userdata, void* obj) { BaseObject* op; for (op = ((BaseObject* )obj)->GetNext(); op; op = op->GetNext()) { if (op->GetTag(ID_IPPFIGURETAG) || op->GetTag(ID_IPPOBJECTTAG)) break; } return op; } void* GetPred(void* root, void* userdata, void* obj) { BaseObject* op; for (op = ((BaseObject* )obj)->GetPred(); op; op = op->GetPred()) { if (op->GetTag(ID_IPPFIGURETAG) || op->GetTag(ID_IPPOBJECTTAG)) break; } return op; } void* GetDown(void* root, void* userdata, void* obj) { return GetObject(((BaseObject* )obj)->GetDown()); } void* GetObject(BaseObject* op) { BaseObject* down; for (op; op; op = op->GetNext()) { if (op->GetTag(ID_IPPFIGURETAG) || op->GetTag(ID_IPPOBJECTTAG)) return op; if (op->GetDown()) { if (down = (BaseObject* )GetObject(op->GetDown())) return down; } } return NULL; }This code only shows Objects with the two restrictive tags - no matter where they reside. Cool!

Looks like I spoke too soon. Some OM hierarchy arrangements will not work with this filtering. I'm exploring alternatives (especially now that the filtering has been expanded). A 'filtered' AtomArray may be the only real approach to a sparse hierarchy - the result will be a list in the TreeView though (only GetFirst(), GetNext(), GetPred()).

Alrighty then. This set works, but it is very loop/recursion oriented so as to traverse every possible branch no matter the filter settings or hierarchical arrange - as best as can be tested.
Note that the filter Booleans are being set in the dialog. I'm being lazy about hiding the variables and using setters instead.

One more change to FindNext() and FindPred() to make this complete. This will stop adding objects multiple times because it will have been already added by a parent as its next or predecesor. Not harmful, but boggling to work with.
