Status in Gecko
This table summarizes some of the broad features related to touch input on the web, and their implementation status on different Gecko platforms:
| Platform | Touch Events | Pointer Events (bug 960316) | touch-action | async pan/zoom | mobile viewport |
|---|---|---|---|---|---|
| Android | yes | no | no (bug 1029631) | Java (bug 776030) | Java (bug 799585) |
| Firefox OS | yes | no | no (bug 960209) | Gecko APZC | Gecko |
| Linux | no | mouse only (disabled) | no | no | no |
| Mac | no | mouse only (disabled) | no | no (bug 1011833) | no |
| Windows desktop | disabled (bug win-touch-issues) | mouse only (disabled) | no (bug 1001440) | no (bug 1086162) | no |
| Windows metro | yes | yes (disabled) | yes | Gecko APZC | Gecko |
Status in other browsers
This table lists support by other browsers as of December 2014:
| Browser | Touch Events | Pointer Events | touch-action |
|---|---|---|---|
| Chrome | ✓ | ✓ | |
| IE desktop | ✓ | ✓ | |
| IE mobile | ✓ | ✓ | ✓ |
| Safari | ✓ |
References
Standards:
- W3C Touch Events (shipped by Safari, Chrome, IE Mobile, Firefox for Android, Firefox OS)
- W3C Pointer Events (shipped by IE Desktop, IE Mobile)
- touch-action is part of the Pointer Events spec (shipped by Chrome, IE Desktop, IE Mobile)
Planning
Current work:
- Mac: Use async pan/zoom (gfx).
- Windows desktop: Fix and enable Touch Events, and implement Pointer Events + touch-action (MS Open Tech, Platform Integration?).
Possible future work:
- Firefox OS: Implement and enable pointer events and/or touch-action (MS Open Tech?).
- Android: Implement Pointer Events and/or touch-action.
- Android: Unify Android and Gecko APZC and viewport code.
- Windows/Linux desktop: Use async pan/zoom (bug apzc-desktop).
- Platform: Implement CSS Device Adaptation to rationalize mobile viewport code (bug 747754).
Notes:
- Just implementing Touch Events and touch-action (without Pointer Events) would allow efficient Pointer Events polyfills, and other developer benefits (including ability to improve responsiveness of touch UIs). This is what Chrome is currently doing.
- Implementing APZC on desktop would allow desktop Firefox to share much of the Touch Events / Pointer Events / touch-action code with Firefox OS.
- Similarly, porting Firefox for Android to the Gecko APZC and meta viewport code would allow increased code sharing with Firefox OS.
