Inertial Scrolling on PlayBook

[tneil]

So far this is looking really good!! I have iScroll integrated into bbUI for scrolling on PlayBook on screens using a title bar. Next is getting it on screens without a title bar. It also has the proper translucent scrollbar and fading effect when scrolling finishes like the PlayBook core OS.

Just going through some OSS vetting with iScroll 4 to make sure we include it in the best possible way for the community before pushing it up to my fork.

Work that still needs to happen:

• Finish the OSS scrub to include iScroll 4 into the toolkit
• Test on non-title bar screens for PlayBook
• Test on BB7 to see if it can be enabled there
• Remove the scroll bar for BB7 to follow UX design for the OS
• Add a data attribute to the screen so that you can opt out of the elastic/inertial scrolling for your screen.

Watching this one closely, will be implementing it immediately into Lemma for the BlackBerry PlayBook when I can!

Finished:

• Testing on non-title bar screens for PlayBook
• Add a data attribute to the screen so that you can opt out of the elastic/inertial scrolling for your screen.

I'm not going to be doing the following for now:

• Test on BB7 to see if it can be enabled there
• Remove the scroll bar for BB7 to follow UX design for the OS

I'll open up a new issue for Inertial Scrolling on BB7 devices... Now I just need to do the OSS scrub and I'll get it submitted

Just merged the pull request

I tried a screen with a title and text-arrow-list on a PlayBook. When I drag my finger on the list, it scrolls but multiple entries would get blue hilighted. Previous version would get at most 1 highlighted or focused only. This looks like a bug or is there a way to workaround it? Ideally I don't think any entry in text-arrow-list should be hilighted on a PlayBook.

Thanks.

Do you have the scroll-effects turned off or on?

[asiayeah]

It was tested without data-bb-scroll-effect="off". After your question, I have tried data-bb-scroll-effect="off", the scrolling seems less smooth (Is it what does the iScroll offer?), but the problem with multiple blue lights remain. So it's possible that it's related to some other changes? I am testing blackberry-bbUI.js-30d614d.zip.

Perhaps, the root problem is why there is a blue hilight going on with text-arrow-list on a PlayBook? It is reproducible with the the following sample codes, too.

Yes the smooth scrolling is what iScroll brings to bbUI. I'll take a look at it. I've added a new issue to track this #54
