How To Cook My Sop When A Dependent Sop Changes

[doc]

Hi,

My Sop(sopA) has a string field that takes a path to a different sop(sopB).

I use this path to query different parameters on sopB and use these

values in sopA. In order to get at these values I create

a string with a "ch()" command and run it like this:

OP_CommandManager *mgr = OPgetDirector()->getCommandManager();

mgr->execute( my_cmd.c_str(), now, &output);

This works great. The problem I'm having is that when a parameter

value on sopB changes I need sopA to recook. Is there a way to do this?

Many thanks

Sorry, not much time to reply. But in short, you want to do something like:

sopB->addExtraInput(sopA, OP_INTEREST_PARM)

where sopB and sopA are the corresponding OP_Node pointers.

HI Ed,

thanks for the reply, I know you're busy

but I got some follow up questions:

How do I go about getting values for sopA and sopB?

I'm guessing I can use "this" in place of sopA?

And for sopB, is there a function that returns an OP_Node pointer

given a string with the path to the node? And if so will a relative

path work as well?

FYI I've also pinged support with this question

Many, Many thanks and much gratitude

figured it out:

OP_Node *thisSop = OPgetDirector()->findNode(sop_path);

OP_Node *chSop = OPgetDirector()->findNode(UT_String(path.c_str()));

if(chSop!=NULL && thisSop!=NULL){

thisSop->addExtraInput(chSop, OP_INTEREST_DATA);

}
