How to get Diagram size in layoutProvider [message #74282]

Hello all,

I am using a layoutProvider to create a grid like layout.
I need to put a column at the left extreme of the diagram space and one at
the right extreme also.
The left hand one is ok as I know I am starting from 0,0.
However I can't figure out the right hand side one.
I was thinking to get the figure used for the diagram and call getClientArea
on it.
However I can't figure out how to get that info into the layoutprovider
class.

Can anyone help ?

Thanks.

There is a helper method on the DiagramEditPart called getChildrenBounds
the method will return the children bounds (based on the current bounds
of the figures)

Hi,

Thanks for getting back to me.
How do I get a handle on the DiagramEditPart.

My class is called GridLayoutProvider and extends
AbstractLayoutNodeProvider.

The two methods are
public Runnable layoutLayoutNodes(List layoutNodes, boolean
offsetFromBoundingBox,IAdaptable layoutHint)

and

public boolean provides(IOperation operation)

I can't see obviously how to get a handle to the DiagramEditPart.

I can get the Diagram as:

ILayoutNode lnode = (ILayoutNode)li.next();

NodeImpl node = (NodeImpl)lnode.getNode();

Diagram di = node.basicGetDiagram();

But still can't seem to figure how to get the DiagramEditPart from here ?

Any thoughts ?

try :

IGraphicalEditPart gep = (IGraphicalEditPart) layoutHint
.getAdapter(IGraphicalEditPart.class);
if (gep!=null){
Map registry = gep.getViewer().getEditPartRegistry();
// then get the diagram object some how
EditPart diagramEditPart = registry.get(diagram);
}

one comment though; avoid using the NodeImpl use Node instead
and use getDiagram instead of basicGetDiagram()
