public class CodeEditorGutter

extends LineGutterPlugin

The CodeEditorGutter interface is an extension of the editor's Gutter interface to integrate with the JDev environment and provide Context information for other Addins.

The CodeEditorGutter does have a ContextMenu available. Use CodeEditorGutter.getGutterContextMenu() in order to attach/detach as a ContextMenuListener. When the context menu is going to popup up, your listeners will be called with the context of the gutter - the view will be set to the specific CodeEditorGutter instance.

Note the contents of the Context to determine what to show in the ContextMenu. If the context menu was popped up by right-clicking on the CodeEditorGutter, the (1-based) line number will be stored in the extra data member with an Integer wrapper, or null if the user right-clicked on a non-existent line. If the context menu was popped up by left-clicking on on a clickable mark that wants the drop down menu, the extra data member will be set with that GutterMark.

When you get the context of this CodeEditorGutter, either by calling getContext() or by what is provided through the gutter's ContextMenu, the view returned in getView() will be the gutter itself, while the owner of the gutter view will be the associated CodeEditor instance.

When creating a GutterMark please use the defined mark order constants defined in this class. This makes it easier to order the marks relative to each other.
