Setting debug point in ADT class

[mwn]

Is there a way to set a breakpoint at a non-executable line in a class using ADT?
I have a class which inherits from another class. I want to debug my class, so that I can see my class constructor executing the class constructor of the superclass. 
The ADT debugger doesn't allow me to set a breakpoint at the method implementation , as it is a non-executable line.

Any ideas, please?

Why not setting the breakpoint at the first line of the class constructor implementation? (of your class or of the inherited class)

I could do that, but with a SAPGUI debug, I can start running in debug mode and just follow the single steps. I was looking for that functionality.

Alas, many SAP GUI debug features are not available in ADT.
