[ jEdit-CVS ] plugins/ProjectViewer/projectviewer ProjectViewer.java,1.93,1.94

[Alan E. <ez...@us...>]

Update of /cvsroot/jedit/plugins/ProjectViewer/projectviewer
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv25596

Modified Files:
	ProjectViewer.java 
Log Message:
Added a NodeSelection possibility for ProjectViewer events.

Attempted to clarify some of the documentation in the package.html for
event.

I think there is a bug in removeProjectViewerListener though - it appears
that after reload Console plugin, I get duplicate events.
