headless usage of GMF rendering [message #67322] Sat, 21 October 2006 17:45 Go to next message

Hi,

I know this question might sound a little bit strange:

Assume we are given a model instance file and a corressponding notation
file. Is there a change to produce an image of the given instance
using the GMF API without launching the Eclipse UI?


Regards,


Alex

Alex,

You can produce an image without bringing up an editor within Eclipse if
this is any help.

See OffscreenEditPartFactory and CopyToImageUtil for details.

Cherie

Thanks for your hint. I found these classes and created a headless RCP
which runs the image conversion.

Unfortunately I run into some problems with the initialization.
Loading the class ImageFileFormat fails with the following exception:

Do I have to add some initialization steps?

Alex,

When the Diagram UI plugin starts up it initializes the preference store
with font values. It is calling JFaceResources.getDefaultFont() and
when a new font registry is created in SWT it requires a Display.

We have not supported this use case in the past, but I don't see why we
shouldn't be able to support it assuming SWT supports this somehow.
Maybe there is another way we can get the default font. I would suggest
you create a bugzilla and someone can look into it.

Regards,
Cherie
