Hi all!
I need to create an editor for logical operators (AND, OR, XOR, etc...) and I can't manage to specify the location of the bordered nodes that I use.
Here is the content of my default layer: I have a main container which has multiple bordered nodes.
In fact, I need two kinds of nodes:
- The first category will represent the inputs of my logical operator. Therefore, I need them on the left side of my main container.
- The second category will represent the outputs of my logical operator. Consequently, they need to be on the right side of my main container.
So far, all I can do is arranging randomly the bordered nodes, it puts the inputs on the top of the container and the outputs on the left side. But again, this is not the expected shape of my logical operator.
Best Regards.

Could you try with a
org.eclipse.gmf.runtime.diagram.ui.figures.BorderItemLocator ?
DBorderItemLocator is not currently capable to keep your preferred side,
but it tries to avoid positions conflicts, overlaps, .. and to locate
bordered items all over the parent.
