Hi

I am looking for examples of how to layout children of containers. For
example I have a Rectangle (Component) that has Ellipses (Ports) on the
border. I am using the Etrice code as an example but the layout is not
quite working for me. Wonder if there is other code smaples or
algorithms for layout.

thanks

Hi,

layouting inside a container is simply done by setting the x and y
coordinates of the inner shapes. These coordinates must be relative to the
next active outer shape. Basically this resembles a plain Draw2d XYLayout.

Not sure what ETrice does on top of that...

Did you have a look into the filesystem example? It shows at least some
basic nesting (a list of sub shapes) or the tutorial (there is a anchor port
right at one of the edges).
