We wanted to share with the community that we have ported a subset of Draw2D and GEF and Tabbed Properties into RAP that is based on the existing RAP GC implementation.

We tried it on our Event Timeline project, which is a GEF timeline we wrote for use in simulations, and it works pretty well. We just have a few scrollbar issues to address.

Cool stuff! I would be very interested to hear how you did it and what
the limitations are.

Greetings,
Tim

This will be very useful. Thanks.

Is it available as part of latest update-site content for RAP ?

Hi Stefan,

At first we had some issues with IE 8, but we cleared those up.
We have tested on IE 8, FF > 3.6, and the latest stable Chrome and Safari.

Hi Tim,

Basically we started with the latest Draw2D, GEF and Tabbed Properties.

We removed code that would basically never work in RAP and reimplemented a few features to be RAP friendly. Most of the re-implementation was in FigureCanvas.

In RAP, we made some changes to the FontMetrics and GC classes, (mainly method stubs) to support some vital pieces and added classes like GCData, Path*, Text*, Region and others, removing disfunctional code.

Besides the FigureCanvas changes to actually show the diagrams and provide scrollbars, the only other large change was to enable drag and drop, which we based on my rundimentary view dragging code (http://www.youtube.com/watch?v=zkW27ZqAL3k). The drag and drop implementation is not ideal, but to be able to bring our GEF projects into RAP made it worth doing. The main drawback to the drag and drop is that it currently uses a job to artificially inject move events into the drag and drop process, which doesn't scale well obviously, but to solve our current domain problems it isn't an issue.

There were very few changes to tabbed properties after we made the RAP and Draw2d changes.

We have a few Zest viewers that work well with this implementation too.

There are a few mouse cursor limitations, but that is to be expected with the current state of things.

Although the approach and implementation were not envisioned for use except to our consumers, I would be happy to share the implementation in hopes that others who find the trade-offs workable, can benefit.

I will post it to bugzilla soon.
