Actually I started it like this, also Marcos extended this idea, but because of the classes generated auto, this was not possible. Let me explain it why: We create a new object and it is a Harbour object. Qt's wrappers accept only pointers. Qt's wrapper functions are combination of pointer as well as other types of parameters. At the level of auto generation of code, it is not analyzed which is a pointer, and which is a non pointer. If it is analyzed at the time of generation, then class methods have to be adjusted to entertain this phenomena. Class method will have to analyse every parameters if it is a pointer or otherwise. Actually I could not find a way to achieve it, though I tried a lot. Anyhow, at present I have an idea how to achieve it, I will give it another thought.
