Rosario – Create Custom Team Architect UML Diagram-MenuItems

There are many ways, maybe to many, to extend Visual Studio.  Macros, AddIns, VSPackages, [see: Visual Studio Extensibility Demystified] GAT-GAX, et cetera and now with Rosario we get even more ways with new features like the Architecture Explorer [see Create your own Progression Provider post].

So, we’ve got a lot of ways to add our own functionality. While the Architectural Explorer is more for visualizing the architecture of your applications [or binaries] it is also possible to make executable commands, not really the best place to do that. I think users will get lost when I hide my commands in there, they are used to the current structure of commandbars and mouse-menu items. We also could use GAT-GAX [did that with the first ideas around testcase generation] to add commands, works also pretty easy… [note: you can install all the possible powertools, AddIns, gat-gax and factories which work on Orcas also on the Rosario CTP12]. 


Anyway, because I think commands should be as near as possible at the thing they act on, for the TestCaseGeneration that would be the activity diagram, I wanted the command on the activity diagrams design surface. Not really rocket science because the Team Architects UML are based on the DSL-Tools.

First, create an normal Visual Studio AddIn project [Creating Visual Studio Add-Ins] and add the necessary code for adding an CommandBar. The only thing you need to figure out is the CommandBar  you want to add your MenuItem at… for the activity designer this is “Activity Designer Context”, for the use Case diagrams it is “UseCaseModel Context” and so on… you can easily get all the names by iterating to the CommandBar collection.


Next, create the MenuItem handler, grab the current file and load the model [see next code snippet]. From here we can do anything with the UML diagram we want to do. For example for the testcase generation I only iterate trough the diagram [ see: foreach (ModelElement … in allElements) ], do some magic and create the WorkItems. But, you also can add ModelElments at the diagram, remove them or change properties.


Getting the model diagram is also pretty straight forward…


Conclusion: adding MenuItems is an easy way to add functionality to your diagrams... although I have to say that this implementation is based on the Rosario CTP12 bits and I don’t expect they stay the same while the diagrams evolve. Anyway, for now, a nice way to play with the UML diagrams.
