Events and GUI’s

An event is the signal(s) that a program receives from the operating systems. Not all events that happen on a computer require the computer to respond. When the program does not respond, the event is quietly disposed of. When the program does respond to an event that occurs, each item is recognized and then associated with a method. This allows the program to respond immediately. The graphical user interfaces, otherwise known as a GUI, is a windows based application. It is the overall interface for a program to guide the user through using it.

An event and GUI are closely related because without a GUI, it would not allow the ease of use for the user. Even for programmers, a GUI is necessary, without it, they would not be able to write the code and events would not be able to happen. Throughout the use of a GUI, events are handled in a specific process. Java handles these through JButton(s). This allows something to be clicked and an event happening after the button is clicked in the GUI.

For example, if Microsoft did not create a GUI for Windows Operating Systems, a user would not be able to efficiently or effectively use a computer. Thus, resulting in no programs to be made or used, unless the user extensively knew command lines to use the program.
