So, how would I go about making my CustomDataType know about its CustomGui and vice versa?

These are added via ELEMENTID id { CUSTOMGUI xxx } in the .res file.

I'd kill for a 'simple' *full* example in the spirit of the CUSTOMDATATYPE_SPLINE (with or without the Spline library accessibility) to understand the requirements and complexities of doing this rather than groping endlessly in the dark murkiness. I have a deep feeling that endless groping is what leads to unstable/crashy code (since there must be correct ways and incorrect ways to do this stuff). If I have to guess or use what might be considered improper methodologies, I can't be held responsible.

I assume you don´t need to specify the customgui in the resource files. The customdatatype should know about it as it simply belongs to it.

All you need to do is

YOURDATATYPEID id {Parameters}

Or do you mean something else? What are you trying to achieve?

You need to overload GetProperties()and GetResourceDataType(LONG*& table) of your CustomGuiData and your CustomDataTypeClass. Also return the string for the resource files in GetResourceSym() for your custom data type and your cusom gui.

This stuff is best explained in a full example. I am currently working on one and hope I can post something this week.

cheers,

Here is some code and such so far (it's a lot). Problem is that I don't quite understand GetProperties() or GetResourceDataType() enough. GetProperties() looks to just specify variable configuration flags of the customgui/customdatatype - I don't need those really.

This is the Description Resource for the plugin object using the customgui/customdatatype (I was led by the docs to believe that the ELEMENTID and CUSTOMGUI should be the same name specified in GetResourceSym() for these) :

Here's the header for the customgui/customdatatype (note: I've omitted the GeUserArea as this code isn't relevant for our purposes) :

Adding the GetProperties to both seems to have worked (just added the KDZ_FALLOFF_TYPE for now).

Of course, there is no GetResourceDataType() in the CustomDataTypeClass (or iCustomDataType). But I do have GetProperties() and GetResourceSym() in both CustomGuiData and CustomDataTypeClass and GetResourceDataType() in CustomGuiData.

Now the problem is working with the non-standard spline/GeUserArea. In C4D, they use the CustomSplineKnot in which to store the points in the appropriate class - but in my case, this spline will not necessarily be C4D-like. Just need the type and the points - stored in KDZFalloff.

Also, when I change the type, C4D crashes sometimes. Probably to do with storing the KDZFalloff* and using it. See, this is where I am confused. KDZFalloff stores the spline data while the GeUserArea (attached to iCustomGui) displays it and monitors user interaction. How does one go between these? I see that the SplineData has a Messages (and Function tables - but hopefully these are only for the library access).
