Explain Look-and-feel

Look-and-feel: The visual impression and interaction style given by a user interface. This is mainly the responsibility of the window manager (that is, in collaboration with the fundamental operating system) running on a specific computer. This refers to style of such things like window title bars, how windows are resized and moved, how various operations are executed through a mouse, and so forth. This is preferable to have a consistent look and feel in a single user environment. Though, a few window managers do permit the individual programs to represent a different look and feel from the predominant style of the host atmosphere. Java's Swing components support this idea by permitting an application to choose a `pluggable look and feel' from those given by a user interface manager. The application running in a Microsoft Windows environment could be made to look like one that generally runs in an X Windows environment, for example. This permits an application to look identical on different platforms; however it can also lead to the confusion for users.
