guys i want to create a .dll file that has its own window so that if i call the dll it will create its own window (like eula license for example)..

im having a bit of trouble doing it, my question is how can i export the object (Dialog), for example just show the ui in a single function without class

i can export functions using extern "C" Q_DECL_EXPORT, next question is how can i export the class::functions, if i export the class can i already access its functions? how? should i access the classname::functionname or functionname only?

note:"im avoiding to use the #include mydll.h i want my dll to be independent, i only call the dlls"
