Hi,

I am not sure if it about GTKmm at all. The system manages windows that  
represent a space for different applications. Each application can be  
written using it's own GUI framework: GTKmm, Qt, Tkinter, and so on. Thus  
maybe your question should be addressed to a "guy" that is responsible for  
sending a sort of "REDRAW_WINDOW" signal whenever it is needed and a part  
of window becomes visible. I guess that should be some kind of System GUI  
Manager that is definitely different in Linux, Windows, Mac OS X, etc.  
Therefor the "guy" you are looking is System.
