Please find attached an updated version, that now has selectable way of working, either standard (works exactly like right-click scrolling), or Drag'n'Pull.
This has been made agains r12026 + latest version of my multiple mouse events treatment patch, that you should apply before this one.
I built r12026 with
* twice_treated_mouse_events-updated.patch (currently last version)
* openttd-left_scrolling-updated_2.patch (currently last version)
(using Wacom) With "standard" mode I noticed that left-button-scroll setting set to standard the map movement it behaves the same as right-button movement, which is nice.
(using trackball) Works fine aswell i think. (don't use it much when I'm playing unless I'm on my laptop which lacks an ancient COM-port)Naming
First I'm not native speaker of English so my understanding of the word "scrolling" might be slightly wrong. Also note that in the patch-screen there is already an option for "Function of scrollwheel".
Personally I'd rather not name translating the map "scrolling" as to me the word "scrolling" is bound to something that is done in one dimension. Such as scrolling with a scroll-wheel or the counterpart on laptops. I don't know about native English speakers but here "scroll" is commonly used as an abbreviation for scroll-wheel. Therefor I find it a bad choice to call this feature "left click scrolling".
Perhaps "left click map movement"?
