In the New World of Mobile and the Touch Enabled PC, Scrolling and Swiping are Fundamental


As we all know the world of computing and software application development is changing. Mobile has ushered in a new era where we interact with our mobile devices through a brand new user interface (touch, gestures and swiping).

Now we are seeing the emergence of this same new user interface capability on the desktop web with some really innovative touch-enabled Windows 8 machines, opening up a whole new world of software application development possibilities for the desktop web. And, there is a high likelihood that Apple will follow suit, adding touch and swiping to their laptops and desktops.

At Alpha Software our goal is to provide a unified product for the rapid development of business applications, optimized for mobile devices and the desktop web - including the new touch/gesture/swiping enabled desktop web.)

The videos below, which are previews of what's coming in Alpha Anywhere - powered by v12, show some of the powerful capabilities in the areas of touch initiated vertical and horizontal scrolling:

Touch scrolling In a Section of the Screen

Touch-scrolling is central to mobile applications. A common design requirement is to display long content in a scrollable section of the screen. In this video we show how you can put content in a Container control and then turn on touch-scrolling for the Container.


List Control - Horizontal Scrolling

A List control is laid out vertically by default. However, in many applications, you might want a List control that is laid out horizontally. When you set a List control use horizontal layout, the list will scroll horizontally if there is more data than can be displayed in the List. All of the options for List pagination (e.g. FetchMore, AutoFetchMore, etc.) can still be used. The 'Horizontal' scrolling option is only appropriate if the List layout is set to 'Freeform'. Horizontal layout is meaningless in the case of a Columnar List. In this video we show how a List can be configured to scroll horizontally. We also show how the List can be paginated using both the FetchMore and AutoFetchMore pagination methods.



 With this capability, apps like the BBC News app for iPhone/iPad   https://itunes.apple.com/us/app/bbc-news/id364147881?mt=8    can be built in Alpha Anywhere - powered by v12

List Control - Snaking Column Layouts

'Snaking' layout displays the List data in a 'grid' of cells that flow from left to right, then top to bottom. For example, consider the 'products' page on Amazon.com when you search for a product. The number of 'cells' per row in the List depends on the List width and the size of each 'cell'. The 'Snaking' layout option is only appropriate if the List layout is set to 'Freeform'. Snaking layout is meaningless in the case of a Columnar List. If there is more data than can be displayed at once, the list will scroll vertically. All of the options for List pagination (e.g. FetchMore, AutoFetchMore, etc.) can still be used. In this video we show how a List can be displayed using a 'snaking' layout.
