|
||
|
|
// This module provides unified touch event handlers by exporting
|
||
|
|
// press, move, release and cancel which can also run well on desktop.
|
||
|
|
// Based on http://dvcs.w3.org/hg/webevents/raw-file/tip/touchevents.html
|
||
|
|
//
|
||
|
|
// example:
|
||
|
|
// 1. Used with dojo.connect()
|
||
|
|
// | dojo.connect(node, dojo.touch.press, function(e){});
|
||
|
|
// | dojo.connect(node, dojo.touch.move, function(e){});
|
||
|
|
// | dojo.connect(node, dojo.touch.release, function(e){});
|
||
|
|
// | dojo.connect(node, dojo.touch.cancel, function(e){});
|
||
|
|
//
|
||
|
|
// 2. Used with dojo.on
|
||
|
|
// | define(["dojo/on", "dojo/touch"], function(on, touch){
|
||
|
|
// | on(node, touch.press, function(e){});
|

|
|
// | on(node, touch.move, function(e){});
|
||
|
|
// | on(node, touch.release, function(e){});
|
||
|
|
// | on(node, touch.cancel, function(e){});
|
||
|
|
//
|
||
|
|
// 3. Used with dojo.touch.* directly
|
||
|
|
// | dojo.touch.press(node, function(e){});
|
||
|
|
// | dojo.touch.move(node, function(e){});
|
||
|
|
// | dojo.touch.release(node, function(e){});
|

// | dojo.touch.cancel(node, function(e){});
