One would expect (not having looked at t he libreoffice source) there to be ifdefs surrounding the GTK2 and GTK3 code. I haven't done any GTK coding of any kind (Xaw and Motif are the limits of my experience). One place to start is to find out how to set up both GTK2 and GTK3 scrollbars. Then look for the GTK2 code and see if there is corresponding GTK3 code in an ifdef next to the GTK2 ifdef. It might be more complex than that though. I quickly Googled scrollbar before work . You might want to try this. https://slackalaxy.com/2017/11/27/gtk3-overlay-scrollbars/. I don't think a reboot is necessary though as the discussion is about and XFCE environment. -- Cheers, Cy Schubert <Cy.Schubert@cschubert.com> FreeBSD UNIX: <cy@FreeBSD.org> Web: http://www.FreeBSD.org The need of the many outweighs the greed of the few.
