[Qt-interest] Why to use dumpcpp -nometaobject ?

[feudenfer]

In the documentation it's said that metaobjects will be created in 
runtime. I'd like to have just COM class headers without extra .cpp that 
I have to include into my project. But seems that option gives 
broken/not full COM interface wrappers. They just crash in runtime.

Probably I don't get clearly enough what this option is supposed to 
give. Could someone (trolls, you!) explain why/when to use 
"-nometaobject" option for dumpcpp ?

Thanks!
