Hi Everyone,

I have recently added a new scroll event handler in my github fork of the BlackBerry WebWorks project.

The event object will allow you to subscribe to scrolling events on the screen.  This will allow you to trap scrolling events and react to new scroll positions.  You can see how these can be combined with CSS & DOM manipulation to create fixed toolbars:

You can find the source code here:

REQUIRED FEATURE ID

========================================================

<feature id="blackberry.ui.event" version="1.0.0"/>

========================================================

SUMMARY

========================================================

static void onScrollStart(callback : OnScrollStart)

static void onScrollEnd(callback : OnScrollEnd)

  });
}

hey Tim,

I have sent a lot of post about the scroll issue on phone gap sencha but still not found any suitable fixes.

we are using the x-blackberry-focusable="true" id="100" x-blackberry-onUp="scrollReg()" x-blackberry-onDown="scrollReg()"

with every element and scroll elements using scrollReg function but this is quite slow and at the time of loading mask

showing this scroll is still working.

Please suggest some optimal solution.

Thanks
