CL_GUI_FRONTEND_SERVICES Documentation

[Former Member]

Does anyone knows where I can find documentation for this class?

Hi,

I didn't found any documentation too. I think it's not available.

There must be something.....

I also could not find anything. Maybe SAP thinks that it is self-explanitory. Anyway, do you have some specific problem, or are you just looking for the documentation. We could probably give you a hand with your problem.
