Yes, we are not having anything like mouse, but even when we try to swipe or drag , it behaves as it is trying to select something like what happens in windows selection "You left click and start dragging to create a range and select things".
I am still confused and have not got the answer.
The buttons works fine, it gets the tap.
But the drag and swipe action does not work, may be some thing is missing.
Using ExtJS 4.1, I see the same behaviour in Chrome 18, but it works fine in Firefox 12.
I have a Planar touch screen connected to my laptop. I tried the Image Viewer sample ("Organizing Images into Albums"). Tapping works just like a left mouse click. But dragging in Chrome does nothing. In Firefox both single and multi-select drag works. In the Kitchen Sink sample, swiping to scroll works in Chrome, but dragging the scrollbar to scroll does not.
It appears the Sencha SDKs have some major bugs in Chrome, or don't support it.
