com.badlogic.gdx.scenes.scene2d.Stage

A Stage is a container for {@link Actor}s and handles distributing touch events, animating Actors and asking them to render themselves. A Stage is basically a 2D scenegraph with hierarchies of Actors.

A Stage object fills the whole screen. It has a width and height given in device independent pixels. It will create a {@link Camera} that maps this viewport to the given real screen resolution. If the stretched attribute is set to true then theviewport is enforced no matter the difference in aspect ratio between the stage object and the screen dimensions. In case stretch is disabled then the viewport is extended in the bigger screen dimensions.

Actors have a z-order which is equal to the order they were inserted into this Stage. Actors inserted later will be drawn on top of Actors added earlier. Touch events that will get distributed to later Actors first.

Actors can get focused. When your game pauses and resumes make sure to call the {@link Stage#unfocusAll()} method so that thefocus states get reset for each pointer id. You also have to make sure that the Actors that were focused reset their state if the depend on being focused, e.g. wait for a touch up event. An easier way to tackle this is to recreate the Stage if possible.
