This is a static solution for use cases like you like to load a list of extensions and display it in the UI as commands that is not possible using the xml interface (as far as I know). If the list of possible extensions relates to the runtime state than might be dynamic needed.

I searched for a solution to this question some time ago and stumbled across the element “dynamic” which can be added to a “menu”. Do you know what the differences are?
The only difference I see between these two solutions is that the class of your solution is loaded at start up whereas my class is loaded when the menu needs to be displayed (at runtime).

You will find all the examples related to the Command API at this link (http://mbaron.ftp-developpez.com/eclipse/commands_examples.zip)

It’s great, i like this kind of example.

I have made the same example in taking into account an expression object for the addContributionItem method. I show how to notify the WorkbenchWindow instance to evaluate the expression object. Thanks to the sources of Eclipse

You can find this example into my training courses about the Eclipse Command API. However these slides are in french. Check the slides number 149 and 150.

Take a moment and think, why people are asking rather than finding ? is it because eclipse has become too complex with little to not so useful documentation and hard to understand the design ?

All developers coding for eclipse know this fact for a long time, its becoming hard to understand often take long to master a specific component/area and often you end up talking to people to understand something you may have not yet used.

Not a good sign for a great product/technology, complexity is the first sign of obscurity
