zOrder on MacOS

[MarioMarinatoSTech]

Our team recently released a MacOS version of our RCP application and the main issue our clients have with it is that the zOrder of the detached windows do not change, regardless of the window with focus. The first detached one is always at the back and the most recently detached is always at the front. On a Windows system, it works as expected: clicking on any of the windows brings it to the front.

Eclipse itself shows this behavior. I even created an issue for this, here.

We tried different approaches to the creation of new shells, varying style bits and parents, but either they yield the same behavior or make the detached windows behave in some other undesired fashion.

As we have our own fork of SWT, we even tried to achieve something by making changes to the code that creates new Shells, passing different values to NSWindow.setLevel(), to no avail.

Do you think it's possible to make SWT's Shells behave on MacOS like they do on Windows?
