<h1>Gestures simulator</h1>
|
|
<p>Used for unit-testing Hammer.js. To test it on the Google Maps view, you should open your
|
|
<a href="https://developer.chrome.com/devtools/docs/mobile-emulation#emulate-touch-events">
|
|
Inspector and emulate a touch-screen.</a>
|
|
Or just open it on your touch-device.</p>
|
|
<p>Currently, it only triggers touchEvents.</p>
