I don't think there's any built-in tooltip events for margins. However, you can reimplement mouseMoveEvent and get the 
line number with QsciScintilla.lineAt(event.pos()) whilst hovering on the margins. The margin number can be determined 
by comparing the margin widths with event.x(). The current margin count can be determined with QsciScintilla.margin(), 
and the width of each margin with QsciScintilla.marginWidth(index). By default, there are five margins. Hidden margins 
have zero width.
