 * Left; and Button #7 = Scroll Right.) This includes X11, with both
 * Xlib and XCB.  So, the "raw button" for "Qt::BackButton" is
 * usually described as "Button #8".

 * If your platform supports "smooth scrolling", then, for the cases of
 * Qt::BackButton and higher, this program will show "raw button" with a
 * value which is too large. Subtract 4 to get the correct button ID for
 * your platform.
