.\mainwindow.cpp(35) : error C3861: 'SetSysColors': identifier not found

As I said, read SetSysColors() docs. Look at the bottom where it says "Header".

Thank you.

Qt is not a programming language but a library.


Perhaps you should read SetSysColors() docs...

#ifdef OS_WINDOWS
quint32 m_ColourElement = COLOR_3DDKSHADOW;
quint32 m_ColourNight = qRgb(100, 100, 100);
SetSysColors(16, m_ColourElement, m_ColourNight);
#endif

Is it right?

Is it right?

No, it's not. First of all, where is OS_WINDOWS defined? Qt does not define such but something similar. Read QtGlobal docs what Qt defines. Secondly, you must include the header mentioned in SetSysColors() docs. Otherwise compiler doesn't know any SetSysColors() function. Thirdly, SetSysColors() doens't take parameters like that. Read SetSysColors() docs what type of parameters it takes.
