Software Development - Eclipse

Preferences are key / value pairs, where the key is an arbitrary name for the preference. The value can be a boolean, string, int or another primitive type. For example a user name might be stored via a key called user .

The implementation of a preference page is primarily SWT code. SWT code is used to create the preference page controls, set the values of the controls, and retrieve the values of the controls. The org.eclipse.jface.preference package provides helper classes, called field editors, that create the widgets and implement the value setting and retrieval code for the most common preference types. The platform provides field editors for displaying and updating many value types, including booleans, colors, strings, integers, fonts, and file names.
