What Does Widget Mean?
Widget is a broad term that can refer to either any GUI (graphical user interface) element or a tiny application that can display information and/or interact with the user. A widget can be as rudimentary as a button, scroll bar, label, dialog box or check box; or it can be something slightly more sophisticated like a search box, tiny map, clock, visitor counter or unit converter.
