Hello,
here's a patch to enhance the Read activity, unfortunately it needed
modification of the evince lib also.
By popular request, it adds a "fullscreen" button to the View tab.
For the scroll/paging changes, my main motivation was that I think it's
important to be able to scroll page by page, especially if using "zoom to fit"
mode, instead of having to manually (and slowly) align the top of the
page with the top of the screen with the arrow keys.
- add "continuous pages" and "single pages" to the "zoom to width" menu
(this should probably be a toggle instead).
- modify evince to map PageUp/PageDown buttons (Fn-Up, Fn-Down, or
gamepad O/X) - without these buttons, "continuous pages" mode can't
advance pages via keyboard.
I'm not sure what the best way to submit these is, please let me know in
case I should get in touch with maintainers directly, or if I should set
up a pull-able git repo.
I wanted to try fixing the nonrotated rocker switch in e-book mode also,
but haven't found a good place to do that yet. Apparently the rotation
happens directly via a shell call to xrandr from the Sugar keyboard
manager, and I'm not sure which signal (if any) the activity could catch
to be notified of the rotation.
Also, I'm not sure if this should be done on a per-application basis, or
if a lower level should always rotate the rocker switch to match the
screen rotation automatically. That may mess up apps that expect the
current behavior though - are there any? Should the game buttons stay
static even when rotating?
Is it intentional to keep the keyboard mapping hardcoded in the evince
lib? The usual evince key binding mechanism appears not to work via the
activity (I think that's why PageUp/PageDown weren't responding). I think
it would be cleaner and more flexible to revive an interface to that and
do the mapping from the activity.
Please send me feedback if you have ideas or suggestions how this should
work.
