#181 horizontal scrollbar


Since 2 years I am using and appreciating a lot Xournal for teaching in front of
many students with the tablet instead of blackboard and chalk.

One feature I really miss is to be able to scroll horizontally (left-right)
through the pages instead of vertically (up-down) as it is now.
In order to emulate the blackboard on a landscape tablet with
landscape projector, I use a landscape A4 paper which I just
divide with an yellow line in two parts: left and wright.
Scrolling to the right rather down would allow the students to view the
last part of written text...

Could you implement it and add an option like

# scroll: true for leftwright, false for updown

please ?

Thank you for letting me known if this is possible.

    Having the pages displayed next to each other horizontally rather than
    vertically should not be all that hard, but it does require changing a
    little bit of the logic of the code (specifically, the manner in which
    scrolling or clicking outside of the page area can cause switching to a
    different page: it's now the horizontal coordinate that needs to be
    checked to figure out where we are). I like the idea -- it seems a lot
    better than the common request (and existing patch) to have a mode where
    2 pages are next to each other horizontally but the overall flow remains
    vertical, which makes little sense conceptually (the only reason people
    request it, presumably, is because Adobe Reader has it; I don't
    understand how one is supposed to work on a document in that mode).

    Unfortunately, I probably won't have the time to do this anytime in the
    near future, but I will add it to the to-do list. Thanks for the good

      I actually like more and more this idea of a horizontal continuous view
      mode where successive pages are arranged left to right. Since I have a
      few hours of free time today, I will try to implement it.

    Done -- the code in the CVS and GIT repositories now has a new menu entry in the View menu, "Horizontal", which should do the right thing.

    Great! Thank you very much Denis! I just installed it and it works perfect.
    I'll try it life in two days in front of over hundert students. I hope it
    will be in the next realize.

    Let me thank you once again for the great work you did.
    xournal is extremely good...
