Menus and Options - Learning LibGDX Game Development - page 252

Here is a screenshot of the final Options window, menu screen, and the opened
Options window:
The thin pixel lines that are drawn all over the widgets are the enabled debug visuals
of TableLayout .
The Options window is now fully functional. It shows up when the Options button
is clicked and hides when the Save or Cancel button is clicked. The settings are only
applied and saved with a click on the Save button.

easily now with just a couple of additional lines of code.
Add the following import line to GameScreen :
import com.packtpub.libgdx.canyonbunny.util.GamePreferences;
