dojox.mobile.ScrollableView

ScrollableView is a container widget that represents entire mobile device screen, and has a touch scrolling capability. ScrollableView is a subclass of View (=dojox.mobile.View). Unlike the base View class, ScrollableView’s domNode always stays at the top of the screen and its height is “100%” of the screen. Inside this fixed domNode, containerNode scrolls. Browser’s default scrolling behavior is disabled, and the scrolling machinery is re-implemented with JavaScript. Thus the user does not need to use the two-finger operation to scroll an inner DIV (containerNode). The main purpose of this widget is to realize fixed-positioned header and/or footer bars.

The animation below shows the difference of scrolling behavior between View and ScrollableView.

Constructor Parameters ¶

Inherited from dojox.mobile.View¶

Parameter	Type	Default	Description
selected	Boolean	false	If true, the view is displayed at startup time.
keepScrollPos	Boolean	true	If true, the scroll position is kept when transition occurs between views.

Inherited from dojox.mobile.scrollable¶

Parameter	Type	Default	Description
scrollBar	Boolean	true	If true, scroll bar is displayed.
scrollDir	String	“v”	Specify a scrolling direction. “v” for vertical, “h” for horizontal, or “vh” for both.
fadeScrollBar	Boolean	true	Use the fade animation to hide scroll bar.
disableFlashScrollBar	Boolean	false	Disable flashing of scroll bar when a view is shown.
threshold	Number	4	Drag threshold value in pixels. The user needs to drag at least the specified pixels before a real drag operation starts.
height	String	“”	Explicitly specified height of the widget (ex. “300px”). If “inherit” is specified, the height is inherited from its offset parent. If “auto” is specified, the content height, which could be smaller than the entire screen height, is used. If nothing is specified, the entire screen height is used.

Usage ¶

Basic usage is the same as for dojox.mobile.View. If you do not need fixed-positioned header and/or footer bars, you should use dojox.mobile.View.

Examples ¶

View header/footer bar example¶

View header/footer bars are fixed-positioned bars that are local to the view to which they belong. That is, the bars stay at the fixed position while their parent view is shown, but when the view moves to another, they go away with the view.

To make a bar widget (Heading, TabBar, or perhaps your custom bar widget) fixed-positioned,

Place it inside ScrollableView
Add fixed=”top” for a header bar, or fixed=”bottom” for a footer bar

<div id="view1" data-dojo-type="dojox.mobile.ScrollableView">
  <h1 data-dojo-type="dojox.mobile.Heading" fixed="top">View Header Bar</h1>
  ....
  <h1 data-dojo-type="dojox.mobile.Heading" fixed="bottom">View Footer Bar</h1>
</div>

Application header/footer bar example¶

Application header/footer bars are fixed-positioned bars that are global to the application (=page). That is, the bars always stay at the fixed position regardless of what view is currently shown.

To make a bar widget (Heading, TabBar, or perhaps your custom bar widget) fixed-positioned,

Place it outside ScrollableView
Add fixed=”top” for a header bar, or fixed=”bottom” for a footer bar

<h1 data-dojo-type="dojox.mobile.Heading" fixed="top">Application Header Bar</h1>
<div id="view1" data-dojo-type="dojox.mobile.ScrollableView">
    ....
</div>
<div id="view2" data-dojo-type="dojox.mobile.ScrollableView">
    ....
</div>
<h1 data-dojo-type="dojox.mobile.Heading" fixed="bottom">Application Footer Bar</h1>
