> is drawn and implemented by the Qt library. It is not so black and white. For example when there is a button when possible Qt will ask the native system to draw a button with properties x,y,z at location x,y So it might be a QPushButton, but it is the OS X or Win32 library that is doing the painting that the user sees. Of course on Windows the idea of "native controls" is confusing as many Microsoft apps have their own "native controls", which one is the native control? I am guessing WXWidgets simply picks the lowest common denominator one and moves on.
