Hi, Actually the event of HW button is limited to access by Chrome (B2G) process only. And Gecko didn't send it via IPC into other content process. This is why your app (in content process) can't listen any event from HW buttom.

After that, I’ve found in GAIA code those two files : https://github.com/mozilla-b2g/gaia/blob/979126f56c6ad3608770049f5ba71cf3e0c3857f/apps/system/js/hardware_buttons.js https://github.com/mozilla-b2g/gaia/blob/979126f56c6ad3608770049f5ba71cf3e0c3857f/apps/system/js/sound_manager.js As far as i understand, some events should be triggered on window object, such as "volumeup", "volumedown", "home", etc. But, in my code, my listener never call the callback : window.addEventListener('volumeup', callback); // callback is never called… Does anybody have a clue ? Note I am working with a peak OS Version : 1.0.1.0 prerelease (standard OTA version) best regards, Rodrigue On 2013-05-28 04:29, Alive Kuo wrote: > Hi, > > Unfortunately you couldn't access any hardware button now from your > app. > See this for reference: > https://bugzilla.mozilla.org/show_bug.cgi?id=839446 [3] Implement > DOM3 KeyboardEvent types for media > > -- > Alive C.
