I have following code, defining the custom SplineControl GUI.
It shows everything, but how to define and draw the spline?

self.spline_gui.MakeLinearSplineLinear(3) is not working?

That should rather work, yes.

Remember that the Spline GUI itself only provides access to the SplineData inside. The actual manipulation of the spline must be done in the SplineData.

After adding ScottA codes and some additional init lines, it works. Thanks!

Additional init lines:
      bc[c4d.SPLINECONTROL_X_MIN] = 0
      bc[c4d.SPLINECONTROL_X_MAX] = 100
      bc[c4d.SPLINECONTROL_X_STEPS] = 10
      bc[c4d.SPLINECONTROL_Y_MIN] = 0
      bc[c4d.SPLINECONTROL_Y_MAX] = 100
      bc[c4d.SPLINECONTROL_Y_STEPS] = 10
      bc[c4d.SPLINECONTROL_PRESET_BTN] = True
      bc[c4d.SPLINECONTROL_ROUND_SLIDER] = True

I'll make a tutorial about what I learned.

FYI.
There's a difference between SetKnot() and InsertKnot() worth mentioning.
SetKnot() will insert knots that are sort of constrained by default. And InsertKnot() will insert knots that let the user freely drag them around in X&Y by default.

You might want to play around with that too for a while to get the feel for it.

Yes, I noticed some of it already.

In the example you give, you cannot change the horizontal position of the knots.
However when you add: lFlagsSettings=0, you can change them.
But I guess InsertKnot is better.

self.sd.SetKnot(index=0, vPos= c4d.Vector(0,80.0, 0), lFlagsSettings=0)

Adding it to one point makes all points possible to change horizontal.

Another question:
I now get the grid, the spline, etc., but I cannot / see not edit X or Y .
Although I added
bc[c4d.SPLINECONTROL_VALUE_EDIT_H] = True
bc[c4d.SPLINECONTROL_VALUE_EDIT_V] = True

In your Tag example (with a res file) there is a little triangle which you can click in order to added values.

I have the same question.
This is the first time I've tried using a splineGUI in a tool plugin. And I'm also wondering why the attributes don't show up in the AM?

I've written a GeDialog plugin with a splineGUI in C++. Which is a little bit similar to this.
But I used the .res file to layout the splineGUI instead of the AddCustomGui() gizmo method. And there is an attribute called OPEN that makes the splineGUI's attributes show up.

I couldn't find any option like that for the AddCustomGui() gizmo method you're using.

So it seems that

bc[c4d.SPLINECONTROL_VALUE_EDIT_V] = True

are not working?

Back to the res file.
