How to change the size of an element in a diagram

[patson]

Hi
I created (in C# using Automation Interface) a diagram and added an element on this diagram. Now I want to change the position and the size of this element in the diagram view. I try unsucessfully to do it with the Attribute Bottom, Top, Right and Left of the class DiagramObjets.
Somebody can help me please!
Regards

Did you remember to call update() on both the diagramObject as the Diagram?

Hi,

This code works for me (in Perl but it's almost the same...)

Code: [Select]

   my $Fix = Win32::GUI::MessageBox(0, "Do you want to update the size of the selected element?", "Info", 4);
    if ($Fix eq 6)
    {
      $DiagramObject->{Top} = int($self->DOTopTextField()->Text());
      $DiagramObject->{Bottom} = int($self->DOBottomTextField()->Text());
      $DiagramObject->{Left} = int($self->DOLeftTextField()->Text());
      $DiagramObject->{Right} = int($self->DORightTextField()->Text());
      $DiagramObject->Update();
      $Diagram->{DiagramObjects}->Refresh();
      # Reload diagram
      $self->EAApp()->Repository()->ReloadDiagram($Diagram->{DiagramID});
    }    

As Geert wrote you should call update but I also call Refresh on the DiagramObjects collection. I don't know if this is necessary. And after that reload the diagram.

The refresh() is only necesarry if add or remove elements to the DiagramObjects collection, and you need the diagram.DiagramObjects collection later on.

Hi,
Thanks for the answer. I do the same things as Magnus but it does´nt work.
After the execution the both class joeClass1 and joeClass2 appear at the same position in the diagram view. I want to change the size of one class.

Here is my code in C#.


                    Object obj2 = collectionElements.GetByName("joeClass1");
                    Object obj3 = collectionElements.GetByName("joeClass2");

                    EA.Element element2 = (EA.Element)obj2;
                    EA.Element element3 = (EA.Element)obj3;

                    EA.Collection collectionDiagramObjects = diagram1.DiagramObjects;
                    Object obj4 = collectionDiagramObjects.AddNew("", "");
                    EA.DiagramObject dobj2 = (EA.DiagramObject)obj4;
                    dobj2.bottom = 2 * dobj2.bottom;
                    dobj2.right = 2 * dobj2.right;
                    dobj2.ElementID = element2.ElementID;
                    if(!dobj2.Update())
                    {
                        MessageBox.Show("Error");
                        return;
                    }
                    collectionDiagramObjects.Refresh();


                    Object obj5 = collectionDiagramObjects.AddNew("", "");
                    EA.DiagramObject dobj3 = (EA.DiagramObject)obj5;
                    dobj3.ElementID = element3.ElementID;

                    if (!dobj3.Update())
                    {
                        MessageBox.Show("Error");
                        return;
                    }
                    collectionDiagramObjects.Refresh();

                    Repository.OpenDiagram(diagram1.DiagramID);

I have found it.
When I have to add an existing element in a new diagram and then change the size of this element in the diagram, I have to change at first the size of the existing element before adding it to the collectionDiagramObjects.
Thanks for our Help
