Hi Viktor,

Yes, this is the final structure, as the handling mode should be dynamic,
please consult the Qt documents. Is in specified cases is recommended to use
the "delete later" feature what is the default for the actual interface
implementation. After consulting the actual Qt documentation and discussions
on the adequate sites please live it at is, is a conscious decision from my
side, to offer the flexibility to adopt the existing and future decisions of
the Qt developers.

This is not black or white issue, it's not a race situation here, studying
the Qt documentations, we need a dynamic approach here. In some situation
the best solution can be different, so please close this issue, I
intentionally put that things in the code, maybe we are less informed, but
studying the Qt documents...
 
But as a final conclusion, WE ARE NOT FACING WITH MEMO LEAK ISSUES regarding
the Qt interface automatically generated. The problem is with our
measurement instruments! We will need help here to demonstrate it, if is the
case. The actual Windows implementation is not adequate to decide the memory
"consumption" as the windows internal are so complicated. I tried to tune
somehow the Pritpals algorithms but without success after studying some
sites, sorry.

So my general feeling is that the 'memory' problem is solved by the
automatic generated code! For these things demonstration we have to work
hardly.

I stopped temporally my thinking...


Best regards,
István
