Sequence Diagramming Questions

[Octavian]

Hello all,

Anybody know solutions to these issues:
1. Somebody made a sequence diagram in my project without using the proper reusable entities (lifelines). Is there a way for me to substitute whatever entity they put in the diagram with the reusable ones? I need to do it without breaking the connections.
2. I need two sequence diagrams to merge. How do I append one to the other? This is of course assuming the same entities are involved?
3. Is there a way to export one diagram to JPG, PNG or any other common format without reporting?

Thank you in advance!

Octavian,

1. Yes you can, via automation. You'll need to set ElementID of the DiagramObject to the Element you want.
Here's the code I use (tested on 8.0.850)

Code: [Select]

       public void setElement(UMLElement element)
        {
            // there seems to be a bug in the com object when calling update on the DiagramObject after setting the elementID
            // workaround could be to create a new diagramObject on the diagram and copy all the settings
            EA.Diagram parentDiagram = model.getWrappedModel().GetDiagramByID(this.wrappedDiagramNode.DiagramID);
            //get the index of this diagramnode in the collection of diagramobjects of the parent
            short index = -1;
            for (short i = 0; i < parentDiagram.DiagramObjects.Count; i++)
            {
                if (((EA.DiagramObject)parentDiagram.DiagramObjects.GetAt(i)).InstanceID == this.wrappedDiagramNode.InstanceID)
                {
                    //found the correct one.
                    index = i;
                }
            }
            //create a new diagramobject
            EA.DiagramObject newDiagramObject = (EA.DiagramObject)parentDiagram.DiagramObjects.AddNew("", "DiagramObject");
            //set the new elementid
            newDiagramObject.ElementID = element.getID();
            //copy position attributes
            newDiagramObject.bottom = this.wrappedDiagramNode.bottom;
            newDiagramObject.left = this.wrappedDiagramNode.left;
            newDiagramObject.right = this.wrappedDiagramNode.right;
            newDiagramObject.top = this.wrappedDiagramNode.top;
            //delete the old diagram object
            parentDiagram.DiagramObjects.Delete(index);
            //reference the new diagram object
            this.wrappedDiagramNode = newDiagramObject;
            // bug reported to Sparx support. If they fix it this original code can be used again.
            //original code: this.wrappedDiagramNode.ElementID = element.getID();
            
        }2. Again via automation you could move the messages from one diagram to another.
3. Using the GUI: Ctrl-T, via automation using Project.PutDiagramImageToFile
