[Ctk-developers] XDOM - decorator pattern

[Marco Viceconti]

Worth to be said because when we agreed to use Qt, I am sure most of  
us were thinking of the GUI, and not of a class from which every other  
class in the framework would inherit.

So before we carry on, at the cost of being pedantic, let me pose this  
question to the whole CTK group:

Qt provide a portable GUI framework, that we agreed to adopt in CTK.

But it also provides some interesting low-level mechanisms, in  
particular a extensive multi-threading library and inter-object  
communication mechanism.  Do we all agree that also this part of Qt  
can be used to build CTK?

Even if we agree, would not be better to ensure that CTK is not ridden  
of Qt code, and find solutions such as the wrapping of the QtObject  
class into a CTK Class?

Cheers

Marco
