Insert a new Element in a available Element

[marine1981]

I search the available diagram. How I get this diagram? I select the Package and then I create a “New Package” with a “New Diagram”. Now, I want insert the New Diagram in the available diagram”. I use the OnPostNewPackage-Event with C#

My tree:

+ Package
++ Diagram
++ New Element for the “New Diagram”
++ NewPackage
+++ New Diagram

Code: [Select]

EA.Package ParentPackage = Repository.GetPackageByID(NewPackage.ParentID)
…
for(short i=0; i < ParentPackage.Diagrams.Count-1; i++)
{
      MessageBox.Show(“Do somethinkg” + i);

}

Sven,

First of all, you can use foreach on EA.Collection, that is a bit more elegant then your for loop.
Further you need to add Something to the Diagram.DiagramObjects collection to put something on the diagram.

I have already inserted a Element into the Diagram. Later, I want connect the both "Elements".

[Geert Bellekens]

To Connect the elements use Element.Connectors on the source and fill in the ID of the target on the new Connector before saving it.

How I can use the EA.Collection with foreach?

EA.Collection DiagramSearch = ParentPackage.Diagrams. ....;//?
foreach(short i in DiagramSearch)
{
 MessageBox.Show("Test: " + Convert.ToString(i));
}

[stao]

foreach (EA.Diagram actDiagram in ParentPackage.Diagrams) {

       actDiagram...();
}

I have got under a selected Package a Diagram in the Project Browser. How I can get the Diagram? It exists only one Diagram. How I can do this one?

[Geert Bellekens]

If you are sure there is only one diagram you can do
Package.Diagrams.GetAt(0)
But you better put a test before that, so something like

Code: [Select]

if (myPackage.Diagrams.Count > 0)
{
   myDiagram = (EA.Diagram)Package.Diagrams.GetAt(0);
}

It does work well. Now, I want conntect both elements.
I have already the ID vom the new element. Now, I need the ElementID from the Element with Stereotype "MyStereotypeName". How I can search the right element in the Diagram?

[Geert Bellekens]

My Idea:

Not much of an idea then  

I think you best loop the DiagramObjects of your diagram, get the ElementID of the diagramObject, get the element using Repository.GetElementByID and check the stereotype.

It's late
My Idea is:

Code: [Select]

foreach(EA.Element ParentElement in ParentDiagramObject)
{

   ParentElement = Repository.GetElementByID(ParentElement.ElementID);
   if(ParentElement.Stereotype == "StereotypeName");
   {
     //Conntect the elements
    }
}

My problem is very simple. I don't kow, how i can get the upper element from the diagram(not Project Browser). The upper element has got a clear stereotyp. The other elements in the diagram has got the same stereotyp. How I can get the the element with the clear stereotype?

My idea was:

Code: [Select]

foreach(EA.Element ParentElement in ParentDiagramObject)
{
//a sample code
MessageBox.Show(ParentElement.Stereotype);

}
But it does not work

[Geert Bellekens]

So do you need the element that owns the diagram, or an element that is shown on the diagram?

Geert

[marine1981]

I need the first element(main element) from the diagram. Is the first element the owner of the diagram?

[Geert Bellekens]

How do you determine the "first" or "main" object in a diagram?
In a diagram all objects are created equal  
The owning element is the element which owns the diagram, which means the diagram is nested under the element in the project browser like
Package -> Onwer of element
- Element -> Owner of diagram
  - Diagram
