    I am looking at the SDK and looking at the virtual Bool GetDEnabling () function.

    I am confused as to how the syntax would look for this function.

    This is what the SDK says.

    \>  
    

    `

    I am not sure what some of those arguments are.
    could someone explain them a little more in depth.

    Thanks,

    ~Shawn

    It's rather simple. You set the state based on whatever. In the case below, it is based on a description state (a checkbox).

    Thannks kuroyume0161,

    It's always much more simple to understand in context.   Thanks for taking the time to help.

    If I was to compile your example and write all of the necessart .res and .h files, would I need to remove node, id, t_data, flags, itemdesc, efrom the arguments when i declare the initial function?

    As you are defining an override function for a virtual function it must retain the exact arguments and return type to function properly. Whether you need the other arguments doesn't matter.

    The declaration and definition should match. In the class header:

    Bool GetDEnabling(GeListNode* node, const DescID& id, GeData& t_data, LONG flags, const BaseContainer* itemdesc);

    and as shown (generally) in the previous post for the class cpp file.

    Need to see code. You are defining GetDEnabling() in the class itself and including the class header in the cpp file? Also, you should be including the plugin resource header ("Ttruesymmetry.h" I assume) in the class header. It can be done in the cpp file but restricts access to your resource descriptions to the tag code only.

    The problem is I am not using it properly in the source.cpp

    I have figured out that I needed to replace "id" with the name of the element, in this case "MAKE_SYMMETRICAL" which is a button. I am not sure what to replace 'node', t_data", "flags", or "itemdesc", with. What are each of those things?
    ~Shawn

    This is what I put in the source to call the function, thus the errors.

    `

    and now I don't get the errors from before,

    but I get this one.

    You are not going about this in the correct way. You never call GetDEnabling() - it gets called for you. By overriding it in the plugin TagData class you created, it is called by Cinema 4D as needed (instead of the virtual one described in the TagData class - from NodeData from where it is derived). Note that at the end of my GetDEnabling() call, I actually call the TagData version so it can handle stock ones that I don't handle.

    See the cinema4dsdk\source\object\circle.cpp for an example. Although it is an ObjectData plugin, the same basic principles are involved.
