In an attempt to understand GEF better, I'm trying to create a standalone
shapes app. My first attempt has been to just wrap the ShapeEditor with
some really simple:

Display display = new Display();
Shell shell = new Shell(display);
shell.setLayout(new FillLayout());
ShapeEditor editor = new ShapeEditor();
editor.createPartControl(shell) ;

This seems pretty promising, but I'm getting the following exception:

java.lang.NullPointerException

tor.java:113)

at com.indigoegg.studio.gui.swt.TestDisplay.foo(TestDisplay.jav a:29)
at com.indigoegg.studio.gui.swt.TestDisplay.main(TestDisplay.ja va:21)
Exception in thread "main"

Can anyone steer me in the right direction?

Thanks!

This will not work. GEF requires Eclipse Workvench to be present. You will
end up recreating part the workbench if you really want the examples to work
properly.

Does this mean that I can't use GEF outside of the workbench or just that I
need to do a lot of work to get it to work outside the workbench? Is there
a good starting point to figure out what I need to do to make the thing work
standalone?

Any input would be appreciated :D

Is it possible to have a "stripped-down" gef
which includes only the minimal part of eclipse (maybe workbench +
draw2d),
ideally in pure Java?

What would be needed for that?

Thanks

There have been a number of discussions about this on eclipse.tools.
I'd start by searching for those. My recollection is that there is a
minimal number of plugins that you need, plus you will have to change
one of them so that it doesn't register some IDE-specific menus with the
platform. After that, you're good-to-go.

if you want GEF without workbench, I guess you should start with Draw2d
and add all editing-functionality by yourself.

I posted a standalone version of the Logic demo a few weeks ago. see the
wiki for more info.
at http://eclipsewiki.swiki.net/50#logicexamplestandalone

the main() is in the LogicSAMain class

for the list of jars to add, check the wiki.

The logic example "as is" cannot run as a standalone application, because
the lookup of the resourcebundle
goes via the API for plugins. So I "patched" the LogicResources class to go
to the resourcebundle directly. For the rest the application runs perfeclty
in standalone.
