question of embedded elements information on diagram

[JiangangWang]

Dear Master,

I have two elements which are separated in project browser, under different packages. But on a diagram, I drag and drop them together, meaning they are bundled.
When I move the outer element, both are moved.

does anyone know how this bundle information store in database? since there is no parent/child relationship in browser, which field of which table store such information?

Thanks a lot

t_diagramobjects. Its simply a matter of positions (left, right, top, bottom)

The magic-move-together is done by EA recognizing the position of the one being completely inside the other.

Thanks for the information.

Do you mean if the position (top, bottom, right, left) of one element is inside the position of another one, then EA recognizes they are bundled?

But the experience I have is that only when a dash-dot-matrix inside the outer element appears when I drop one element onto another, then they are bundled.
If only position is inside, but no such dash-dot-matrix appears, they should not be bundled?

Thanks.

There are two concepts here

- ownership
- visual embedded

If you see the dotted edge when dropping an element onto another, that means EA will change the ownership of that element to the element you are dropping it on.

Ownership can be view in the project browser as the "child" element will be nested under the "parent" element.
Visual embedded is only a thing in the diagram.

The dashed rectangle is the area where EA definitely sees the inner as embedded. Not sure how this is calculated. Probably a certain fixed amount. Leave enough space and EA will recognized them as embedded pair.
