Reading diagram informations using GMF API [message #469958]

Hi,

I'm reading a saved file example.umlclass_diagram in Java/Eclipse3.3M6.
I'm using the interfaces from org.eclipse.gmf.runtime.notation and it
goes pretty well.
But when reading LayoutConstraints on a node that is a UML Class the
getHeight() and getWidth() methods return always -1 and not the value
from the XMI file.
<layoutConstraint xmi:type="notation:Bounds"
xmi:id="_oVeGZe5KEdu4M7x4CSjD-A" x="72" y="108" width="169" height="181"/>

On the other hand, getX and getY methods are OK.
I don't know if the problem come from gmf or uml2tools or from me ;).

Any idea ?

Philippe

Hello Philippe,

Well, it is strange enough. While the diagram is being reopened, it uses
the both coordinates and size of constraint to place the figure.
As you may check, the editpart's that were explicitly set to be very big
remain very big after reopening of the diagram :).
So, the problem is most probably somewhere in your script.

Could you provide some representative details of it?

Regards,
Michael

Hi Michael,

I relaunched my program and now it works ???
It seems I was too tired last week to correctly read my output.
Sorry to have bothered you.
The -1 came only for the node with default size,
so I have a true question this time,
how to find the height and width of a Node with default sizing ?

Regards,
Philippe
