How can I change, in python, the number of gridlines (vertical or horizontal, it doesn't matter) of a SplineData field?
I know that I must use:

SplineCustomGui.SetGridLineCountH(n)

for setting the number of horizontal lines. But how?!?!

If, at least, I knew how to get the SplineCustomGui of my SplineData.
But that is not clear in the SDK
If I can't even get the SplineCustomGui of an element, how am I supposed to use SetGridLineCountH(n)?

Damn! I can't even create an instance with:

customgui=c4d.gui.SplineCustomGui()

What can we do with this class?!?!?

This is exasperating!!!
How is it that something as simple as changing the number of gridlines of a spline data element proves to be soooooo complicated?!
If a class is not accessible, why is it in the SDK?

I have read this in the C++ SDK:

Spline data type (CUSTOMDATATYPE_SPLINE) for the SplineCustomGui GUI. Cannot be instantiated directly.

If it can't be instantiated directly, how can we instantiate it indirectly?

Hello Rui, _

GeDialog.AddCustomGui() instanciates it internally and returns a reference to the created BaseCustomGui instance. I couldn't find a way, in Python, to retrieve a custom-gui that was instantiated by the dialog-resource loader.

But afaik you are currently working on an Object plugin. Afaik we are not able to obtain the BaseCustomGui instance from descriptions. I'm sorry but I can not tell you how to do what you want to achive. I'm actually not even sure how to do this in C++. An official statement would be very appreciated!

Thank you for the replies.
So, Maxon, if it is impossible to get access to that, why is it in the SDK?

It's in the SDK because (same as what Niklas said before) GeDialog.AddCustomGui() creates an instance of a SplineCustomGui in a dialog if you call it with CUSTOMGUI_SPLINE.
But when you declare it in a description you don't have access to the SplineCustomGui, only the SplineData. In that case in the resource description file you can set the number of grid horizontal/vertical steps with GRIDSIZE_H/GRIDSIZE_V flags. You can look at the Spline Deformer resource file to see how a SPLINE description element can be declared: resource\modules\objects\res\description\osplinedeformer.res.

I have set the grid divisions in my description file.
But my plugin creates sets of knots dynamically and I would like to match the grid divisions with the number of knots created.
It is a shame that it can't be done
