Border Item Rectilinear router [message #134763]

There is a nice example showing the Border Item Rectilinear router on the "New and Noteworthy" wiki page (section
"Improved link routing").
Is there also example code showing how to generate this behaviour? Do I need separate nodes for those little Borderitems
or would it suffice to have model elements /nodes for the components only (and maybe for the link also)?

Any pointers appreciated as this functionality is just what I need.
Kudos to the devs for including it in the 2.0 release!

Hi Norbert :

The BorderItemRectilinearRouter is not enabled by default

The way to enable it is to override ConnectionLayerEx
#getRectilinearRouter and make it look like this

public ConnectionRouter getRectilinearRouter() {
if (rectilinearRouter == null)
rectilinearRouter = new BorderItemRectilinearRouter();
return rectilinearRouter;
}

you can have your own connection layer by overriding the
createPrintableLayers method in your RootEditPart and changing it to
look like this:

protected LayeredPane createPrintableLayers() {
FreeformLayeredPane layeredPane = new FreeformLayeredPane();

layeredPane.add(new BorderItemsAwareFreeFormLayer(), PRIMARY_LAYER);
layeredPane.add(new MyConnectionLayerEx(), CONNECTION_LAYER);
layeredPane.add(new FreeformLayer(), DECORATION_PRINTABLE_LAYER);

return layeredPane;
}

you will notice that in this method i'm creating MyConnectionLayerEX
instead of the default ConnectionLAyerEX

Now, for this router to work the border Item Figure position had to be
set otherwise it will not work as expected, if you have troubles
initializing the position on the figure you can always subclass the
router and override the method protected getBorderFigurePosition and
calculate the position in any way you like

i hope this helps

Hi Mohammed,

I refer to an answer where you explained how to setup the
BorderItemRectilinearRouter. You wrote:

What do you mean by "your RootEditPart"? I debug my editor a bit and
none of my generated classes extends any RootEditPart.
I only found
org.eclipse.gmf.runtime.diagram.ui.editparts.DiagramRootEdit Part, which
seems to be something from the GMF runtime called by the runtime itself.
How can I override there any method? I need to install my own
RootEditPart I assume but I don't know how.

Cheers,
Hauke
