[Touch] Can't scroll the view unless touching the space between pages
From #91:
- if you put your finger on one page and then move the finger while keeping it on the screen, Slicer should select all the pages you have "touched"
Pages that were "touched" while scrolling in this way shouldn't get selected.
Shouldn't? *Should!
The bug is that currently they don't get selected, but they should.
The idea is that:
- the user put a finger on a page
- long press
- the user starts moving the finger on the pages -> all the pages between the first one and the last one that he touches get selected
Currently you can't do that, you have to tap on every single page.
By now, only Android works like that. AFAIK, not a single app on gnome supports such behaviour.
I'm talking about a different thing.
When I emulate single-finger touch events using the mouse, I have the following behavior: I can scroll the view dragging the "finger" around, but as soon as I "lift my finger", the page my "finger" was touching gets selected. Which is not what I want, I want to just scroll around.
Do you have this problem? Maybe this is only happening to me because of the emulation.

Interesting, that sounds a lot like rubberband selection using a mouse. Can you tell me of a couple of Android apps that work that way? I haven' run into this myself.
I can scroll the view dragging the "finger" around,
Not "around". Scrolling using a finger works only if I put my finger in those empty areas between pages. If I put my finger on a page when I want to start scrolling, it doesn't scroll.
as soon as I "lift my finger", the page my "finger" was touching gets selected
If I succeed in scrolling the view, nothing happens when I lift my finger. If I do not succeed, then yes, the page get selected only after I lift my finger.

a couple of Android apps that work that way?
Like: Gallery, google file manager (it's the "Download" icon), Google Foto.
Try with some famous file manager. I think this is a quite common UI.

+10 points for going to the trouble of recording the video.
Now I see what you mean, and I can't replicate that using touch emulation, so I won't be able to solve it.

Wow, thanks a lot, I had no idea you could do this. It will surely come in handy. But anyway, this would belong in another bug report, and I don't advise to open new ones related to touch support, since I won't be able to work on them.

That's way I think this is a "long-term" issue. I gave it for granted that you didn't have a touchscreen laptop (just a guess. They're not so common), thus -> no way to test touch features. :)
Glad I could help!
