Interface ActiveLineRangeListener

All Superinterfaces:
EventListener
All Known Implementing Classes:
Gutter.TextAreaListener
public interface ActiveLineRangeListener extends EventListener
Listens for "active line range" events from an RSyntaxTextArea. If a text area contains some semantic knowledge of the programming language being edited, it may broadcast ActiveLineRangeEvents whenever the caret moves into a new "block" of code. Listeners can listen for these events and respond accordingly.

See the RSTALanguageSupport project at https://github.com/bobbylight/RSTALanguageSupport for some LanguageSupport implementations that may broadcast these events. Note that if an RSTA/LanguageSupport does not support broadcasting these events, the listener will simply never receive any notifications.
