Introduced
Gecko 2.0
Inherits from:
nsISupports
Last changed in Gecko 2.0 (Firefox 4 / Thunderbird 3.3 / SeaMonkey 2.1)Implemented by: @mozilla.org/widget/hapticfeedback;1 as a service:
var hapticFeedback = Components.classes["@mozilla.org/widget/hapticfeedback;1"]
.getService(Components.interfaces.nsIHapticFeedback);
Once you have the service, you can initiate haptic feedback (that is, cause the device to vibrate, if it's supported) by calling performSimpleAction():
hapticFeedback.performSimpleAction(Components.interfaces.nsIHapticFeedback.LongPress);
