Migrating RCP application and extensions from GMF project [message #1414101]

Hi all,

I am currently trying to rebuild a GMF-based application with Sirius. While
defining the actual editors works fine I am still a bit confused about the
application frame.

In GMF the generated editor plug-in can also act as RCP application, since
it contains menu entries, an application class and so on. With Sirius there
should probably be a dedicated plug-in for the "main application" which is
then maintained independently from the editors?

With regards to extensions I used to utilise Xpand aspect templates for
injecting them before generation.

One small example is that the palette should be placed on the left side for
example:

«AROUND additions FOR gmfgen::GenEditorView-»
@Override
protected int getInitialDockLocation() {
return org.eclipse.draw2d.PositionConstants.WEST;
}
«ENDAROUND»

What would be the appropriate approach to convert such extensions to Sirius
in general? I guess the right way to go would be a separate plug-in
containing custom classes which are injected/registered using extension
points. Is that correct? Maybe there is some reading material or example
available?

TIA,
Axel

Hi Axel,

indeed, contrary to what you used to do in GMF Sirius is not based on
code generation but on model interpretation.

Consequently, you're right saying that you cannot inject generation
templates to modify the generated editor code.

However, I think you still have the possiblity to use eclipse extension
points to customize the Sirius Diagram editor for example. That has
never been done to my knowledge, but you may subclass the
DDiagramEditorImpl provided by Sirius or try other GMF extension points.

Please let us know if you find a solution for your issue.

Hi Alex,

thank you for elaborating on these questions. After I completed some other
tasks I am going to do some tryouts and report back afterwards.

Regards,
Axel
