When I searched Google for custom controls, I could only find a way to extend the existing controls.
However, I want to know how to make a control from scratch like the attached picture.
Specifically, I want to make the shape of the tree over there so that I can move the circle like Progress bar and register the writing.
Can i create a new control by adding detailed functions like this?
I want to make this app, so wpf and other native platforms are fine, not uwp.
