To print the GEF diagram without viewing in the screen! [message #247696]

Hello folks,

Currently the diagram we draw in GEF are drawn in the screen since the
'GC' class is attached with 'Display'. I wanted to paint this generated
diagram in an SWT Device other than 'Display', say 'Printer'.

I wanted to send a GEF diagram to a Printer without painting in the
Display.

Is it possible?

Regards,
Madhu

Have a look at PrintGraphicalViewerOperation. If that's not exactly what
you need, there are a lot of threads already posted about dumping a
viewer to an image, etc.

Hello Ben,

Both the approaches using PrintGraphicalViewerOperation and viewer to
image conversion need the GEF figures to be available in a graphical
viewer. Isn't it?

I wanted to print it even before opening it in the graphical viewer.

Is it possible?

Regards,
Madhu

Why? Don't you want to just hand off your model input to the viewer, and
have it build up all the figures for you? You can instantiate the viewer
without it being visible on the screen, if that's your concern.

If you are building the figures manually, then you should still be able
to use PrintFigureOperation (the superclass) or some aspects of it.

Yes, This is exactly what I need! How can I instantiate the viewer without
it being visible on the screen?

Check out LogicPrintAction in the logic example.
