[news.eclipse.tools.gef] Re: GEF right for block editor?
Thanks for the answers. At this point, I'm thinking about trying to port the Vergil editor from Ptolemy to a plug-in. It is a Swing application, which I think is okay for eclipse, but can I use Swing with GEF?

My understanding is that it is already set up using a viewer-controller-model architecture in swing. It's a very nice looking editor. You can check it out at http://ptolemy.eecs.berkeley.edu/ptolemyII/ptII4.0/ptII4.0.1/doc/design/usingVergil/index.htm

Hello,

I need a block editor, and I'm wondering if GEF is the right way to go.

Looking at the examples, I notice that the routing is not that good (or
non-existant) and the display is not that nice.  These may be problems
with the exmamples though, and not GEF.  So, 1) Does GEF providing any
auto-routing (and specfically 90 degree only routing).  2) Is it easily


See ShortestPathRouter. It is NOT orthogonal.


IsnÂŽt that what the ManhattanRouter is?


possible to improve the display with say thicker lines, anti-aliasing, and
maybe even rounded corners, for example? 

We use what SWT gives us.

The second problem I'm seeing is the eclipse platform itself seems to
support only one window per file. When working on a hierarchy of block
diagrams, one needs to be able to double-click on a block to open up its
sub-block in a second window and be able to alternate between the two
editing both the top block and sub-block. Is this possible? The only
solution I see is to used a tabbed widget in a single window, but I think
this would be really non-standard for a hierarchical block editor and not
well liked by the user. 

You can do tabs or browser-style navigation.


Check out the example extension for MultiPageEditor.
In the IBM Webtools Examples.The XSD-Editor is a navigator style gef editor,
while the xml editor is tabbed. (as is the plugin maifest editor for example)
