The following scroll width functionalities are added to QScintilla:
setScrollWidth, getScrollWidth, setScrollWidthTracking and
getScrollWidthTracking.
This allows setting a lower value for the initial scroll width (default is
2000 pixels). Consequently, the horizontal scroll is only visible if the
SQL lines become bigger than window width.
The scroll width, though, is never reduced by Scintilla for performance
reasons.
See this for explanation:

And see this for a possible implementation of a fully adjusted scroll
width with fixed-width fonts:
