How to draw Button class in libgdx

Question

I know that libgdx has this Button class that seems so easy to use, but I wonder why the draw method is set protected?

In that case, how should I draw the button?

Scene2d Button

Answer 1

Button is also an Actor. So you would put it on the Stage and the framework would draw it. Here is some more documentation on how this fits together.

Answer 3

Button is an Actor, so it is used with Stage. There is official documentation for scene2d. Button is in scene2d.ui, which is a UI framework on top Stage, which is a general purpose 2D scene graph. There is no official documentation for scene2d.ui yet. You can see UITest though.
