Windows on the desktop are just one of many objects used in a graphical user interface (GUI)– buttons, drop-down list boxes, pop-up menus, are just some of the many others. Regardless of their particular appearance, tasks, and structure, all such GUI components share some common functionality– which is handled in a manner unique to the actual component.
Define an interface, GUIComponent, with the following methods:
onClick– void-returning and accepts a single integer parameter
onCursorFocus — void-returning and accepts a single integer parameter
move — 3 overloaded methods : all boolean -returning; one accepts a pair of integer parameters ; the second a single parameter of type Position; the third a single parameter of type Dimension
resize– boolean -returning and accepts a pair of integer parameters
