Hello!
Recently I discovered a UIToolkit and watched several lectures about it to get information about custom controls, but all the videos were about creating a custom layout, not controls/elements itself. I want to create a slider with multiple handles (like in Gradient editor), but with my own visualization for slider/handles/background and so on. Is it possible, or I have to stick to the default controls?
Yes it’s possible there are several examples in these forums.
We have example of custom controls in the manual, here’s one to get you started:
