Hello Bastian,

Help is always wanted. Welcome to the team!

Let me do some history first.

Last year there was a GSOC project to migrate umbrello to QGraphicsView [0].
You can find the code at [1] and [2].
Last time I tried to build was not successful. The code tree was not touched since 5 months and is
therefore "old". In short: no output for trunk.

In 2008 there was the first GSOC project with the aim to port umbrello to QGraphicsView [3].
The tree can be found at [4].
It is fully Q3-free, builds nearyl without a warning, and is kept in sync with trunk by me.
You can load xmi-files and draw diagrams. Some problems and bugs still exist and should be solve befor a merge.
In the last few weeks we tried to reduce the differences between this branch and trunk to be able to merge soon. See [5].

I think a good start would be to work in [4] and fix some drawing issues.
For example try to draw a sequence diagram, save it, and then reload it. You will see a lot of problems.

Does this sound good? If you have any questions, feel free to ask.
