Observing and requesting better support for panning (horizontal as well as vertical scrolling) in Flash player across all OS platforms and runtimes via ubiquitous input devices.
So, Flash player 10.1 is available in beta and includes mobile device oriented new features such as multi-touch gestures. Smart! Makes sense with Adobe strategy of delivering to emerging mobile devices. However there are a few million of us already using desktops and laptops with track pads, mouse wheels and mouse trac-balls who are feeling a bit ‘inhibited’. Flash is being used more and more to deliver applications either via browser or the AIR runtime. Such applications immediately feel somewhat inferior when a user cannot scroll or pan a view as they normally would native applications. Arguably ‘Rubbish’ rather than ‘Rich’ RIA in such cases.
For a long time the
MOUSE_WHEEL events without any such workarounds. However
MOUSE_WHEEL currently only facilitates vertical scrolling in any case.
We need to facilitate horizontal as well as vertical scrolling (panning) of content in response to events from ubiquitous input devices.
A few prominent applications I use often, which suffer:
- TweetDeck : AIR based. High discoverability of lack of horizontal scrolling support
- Adobe online store UK : In browser Flex application – Flash being used in an attempt to emulate HTML – no vertical scroll wheel support for Mac users
- Adobe Flash builder : Design view (Java application with Flash based view)
- Adobe Catalyst : Art-board view (Java application with Flash based view)
Adobe actively invite comment and suggestions on their products. More widely/easily through the Feature request/bug report form. They have opened up the bug tracking system for a number of products. Flash player being one of them. There is an active bug report with regard to this issue and I would encourage anyone with an opinion to contribute to the discussion and/or add weight by voting. Just sign up and access FP-1262. There is an active drive from within Adobe to help from the community to improve the quality of Flash Player and AIR.
As for the solution I think I’d like to see something along the lines of… Extending the
flash.display.InteractiveObject with a ‘
panEnabled‘ boolean property defaulted to
false which, when
true, allows the object’s Panning behaviour/event broadcasting (akin to doubleClickEnabled mechanism). So, when panEnabled is true, if the mouse pointer is over the InteractiveObject, and the user makes a ‘pan’ gesture, the frontmost panEnabled InteractiveObject broadcasts
flash.events.MouseEvent.MOUSE_PAN events containing with the additional properties :
offsetY. Text based InteractiveObjects should default to
panEnabled = true. Further, I’d quite like to see mechanisms to facilitate behaviours of nested pan-able objects. E.g. on a Mac, the front-most display object gets scrolled until it can scroll no further, then if the user continues the scroll input, the containing display object then scrolls.
In rounding up, the best place to contribute your opinions on this subject and have them heard by Adobe is here : FP-1262.
