Interface GutterColumnListener

All Superinterfaces:

java.util.EventListener

public interface GutterColumnListener

extends java.util.EventListener

The GutterColumnListener interface should be implemented by clients interested in receiving notification events associated with GutterMark instances within a GutterColumn. It is also used for fetching the tooltip that should be displayed for a GutterMark when the user hovers the mouse over the marks' icon.

For example, a markMoved() notification is generated when the user adds or removes text from a prior line B before line A that a GutterMark such that line A shifts upwards or downwards as a result. A markRemoved() notification is generated when the user removes the line that a GutterMark is tracking. Tracking GutterMarks are defined as tracking the beginning of a line. A markClicked() notification is generated when the user clicks on a GutterMark.
