Overlapping tap zones

3m2vinatohr04 · 04-17-2021, 06:44 AM

Hello everyone,

I'm trying on changing the next and previous tap zones to the following:

1 wide zone for the next page and 1 smaller zone right smack in the middle for the previous page

The problem is it at the overlapped zone, the next page is being triggered instead of the previous page. Is there a way to set the z index of the tap zones?

Not without code changes. IIRC, Next is indeed over Prev (on the basis that it's a much more common occurrence than Prev

).

c.f., registerTouchZones @ frontend/apps/reader/modules/readerrolling.lua (reflowable documents) & frontend/apps/reader/modules/readerpaging.lua (non-reflowable documents).

I set the whole screen to be a next page button (except for the middle which brings up the menu), and used swipe to page back. I rarely do previous page.

Right, that's another viable approach, as swipes > taps (in terms of gesture detection, I mean. I hate swipes ^^).

(Note that, unlike the tap zones Z order discussed above, that's a general rule: detecting a gesture requires a finger up event, and if the finger moved far enough, that makes it a swipe instead of a tap, so, by definition, swipes > taps).

Thank you for pointing me to the right lua file!

Great suggestion. Will try this setup.

UPDATE:
Finally found the solution for this!

In order to change the z-index for the forward and backward zones, the order in

Code:

overrides = {},

must be change in these files:

Passersby: don't actually empty the table. Keyword being "reorder", not "empty".

The gnarly details involve building a depgraph from these lists, and insertion order is preserved.

TL;DR: A simpler tweak would just be to re-order the original registration of the tap_* zones, which is what I linked in my original answer.
