Sometimes it may be usefull to peek at the source of some classes from a jar, just think to rt.jar), using Ctrl-click. The problem is that if "Link with editor" option is selected, the whole jar is exploded in "Package Explorer", and that is annoying when you you just wanted to have a rapid look and you are not interested to the class context. "Link with editor" should implement a filter to selectively enable it on source folders, excluding all the jars, or enabling them selectively with something similar to "Step filters" of Debug view.
Moving Dougs bugs
This would be a very nice feature when debugging; I find it very annoying to have the entire JRE class list expand because I stepped into java.lang.
Created attachment 55828 [details] Screen shot of expanded package explorer. The only package that should be expanded is java.lang
I agree. When rt.jar gets put into the context, the tree is exapanded so that all packages (but not their contents) are visible. Not only does this take time, but there are probably more packages in rt.jar than there are classes in any one of my plug-ins, which means mylar is, in this case, making use of the project explorer more difficult. I'm now in the habit of turning off "Focus on Active Task" on the Package Explorer (but whenever I activate a new task or restart eclipse it comes back on, which I will file as a bug if it isn't already). Also, this problem occurs when "Focus on Active Task" is selected, whether or not "Link with Editor" is selected. I can think of two solutions: 1) Use the Resource Monitoring Exclusions (or another list defined in the same way) to exclude packages from view in the Package Explorer 2) When I view java.lang.Object (with Hierarchical Presentation), the full package tree is shown, rather than just java -> lang -> Object. Limiting this to only the parent packages of the selected class would greatly reduce the amount of clutter
Sorry to confuse the issue. I think the situation I described in comment 3 and 4 is actually fixed in Bug 148759. I'm not sure if that fix applies to this bug as well, but it seems like the two might be related -- the choice of the word "exploding" in the initial post makes me think its the same issue.
As per http://wiki.eclipse.org/Platform_UI/Bug_Triage_Change_2009
Remy is now responsible for watching the [EditorMgmt] component area.
+1 I too find it useful to have a filter associated with the "Link with editor" feature, as per the original description of this bug.
