Transcript Plug-In example

Plug-In example
• We want to contribute a new view – “Java files”
view
• The view will contain a list of java files selected in
the “Resource Navigator view”.
• Selection changes in the “Resource Navigator
view” have to be properly reflected in the “Java
files” view
• “Java files” view should also respond to user’s
“double-clicks” by opening an editor for selected
file.
