Does stroke to path essentially create two different objects?

Question

In inkscape does stroke to path essentially create two different objects?

For example if we have a square with a stroke and we do object to path and then stroke to path we can now manipulate the "Fill" and the "Stroke" as if they were separate objects. Are they still linked in any way?

This is a time market youtube link that shows a demo that illustrates the question.

IIUC they are still linked in the sense that if we click on the select tool, we will be selecting the whole thing. If we then do path> break apart then we get two separate objects?

Kind of a broad question - just trying to get a better grip on what the commands are for / underlying semantics.

Answer 1

Object to path removes path effects and generates a bezier curve which looks the same. Texts and Inkscape's preset shapes such as rectangles and ellipses aren't initially bezier curves when one draws them. For example path effects do not function with them. After applying object to path they become bezier curves and path effects & path editing tools work with them.

Objects can have a stroke. Stroke to path generates a path (=a closed bezier curve, single or combined) which covers the same area as the stroke and has the same fill color as the stroke had. You can insert a stroke to a path which was originally a stroke.

If you have a filled shape with a stroke and apply stroke to path, the fill disappears and you have a closed path which covers the area of the former stroke. The path is a combined one, because it has a hole. If you apply Path > Break Apart, you get the hole area as a different filled path.
