Control Nodes
Overview
Control Nodes are the User Interface (UI) items you add to your program that the user interacts with. Examples are Buttons, Sliders, and TextAreas. Because every kind of control is a descendent of the Node class, they all share common methods. However, you should investigate the API for any particular control you want to use because they also have methods that are specific to each kind of control.
