The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Dynamically changing the options in a menu based on the content of the node in the displayed tree

Asked by M5Driver in Eclipse

I have a plugin that displays a tree.  When you right mouse click on one of the nodes in the tree, a menu appears with navigation buttons as well as other actions that someone can take on node of the tree.  I notice that the navigation buttons are managed through a DrillDownAdapter that seems to be able to query each node and then figure out if it should grey out certain items, like if it is at the lowest node of the tree it will grey out the arrow to go lower in the tree structure.

I have searched all around for an example to basically do the same functionality but come up empty.  Based on a string stored in each node, I want to be able to grey out certain items in the context menu just like the drilldownadapter does for the navigation.  Right now I am adding the menu items like

manager.add(myAddedMenu);

which shows all the time.  Anyway, any help at all would be appreciated.  I am using the latest version of Eclipse.Start Free Trial
