AWT Controls

In this topic, we will discuss AWT Controls.

Every user interface considers the following three main aspects:

UI elements : Thes are the core visual elements the user eventually sees and interacts with. GWT provides a huge list of widely used and common elements varying from basic to complex which we will cover in this tutorial.
Layouts: They define how UI elements should be organized on the screen and provide a final look and feel to the GUI (Graphical User Interface). This part will be covered in Layout chapter.
Behavior: These are events which occur when the user interacts with UI elements. This part will be covered in Event Handling chapter.

Every AWT control inherits properties from the Component class.
