what does "eyeball this" mean? In this case the control y value is 2x
the y value of the ovalshape. Is there a rule here? doesn't seem like
a general-purpose solution.
According to the language reference, an order-1 curveshape has one
control point:
1--A quadratic Bezier curve is drawn using one control point.
So, you do get a nice curve. The issue is to find the relationship
between control points and the quadratic Bezier. I believe 1-order
and 2-order curveshapes that use one and two control point are fairly
standard. Although REALbasic doesn't say what the relationships are,
they are likely the same as the relationships found elsewhere.
But I do wish that REALbasic told us precisely what the control
points do. Seems like it's their job.
