Just want to know how the IMPLEMENT_APP() macro in wxWidgets work, how it replaces explicitly stating main();, how it initializes the whole app and the actual code.
Thanks in advance,
Can't you see that for yourself by looking at the macro definition in the header files?
Back when I was using wxWidgets (ugh!) there were some very helpful dedicated forums around, so you might be more likely to find an expert who can help you with wxWidgets quiestions there.
