The I18n Test Wizard Format property editor sets the POSIX regular expression that the Internationalization Test wizard uses to identify all internationalized strings. By default, this setting returns all strings that are parameters of getString (notice that getBundle is committed). For each returned string, the Internationalization Test wizard looks for a matching key and value in the source file's resource bundle.
You can use the Internationalization Regular Expression Format combo box to choose from one of the IDE's preset regular expressions or write your own. The Arguments section contains a list of variables that you can use in your regular expression.
