SWING - Controls
Every user interface considers the following three main aspects −
UI Elements − These 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 the Layout chapter.
Behavior − These are the events which occur when the user interacts with UI elements. This part will be covered in the Event Handling chapter.
