Nice Paging control for scrollableViews for Titanium Appcelerator

Hi,

I stumbled across this module and I have recently started to develop using appcelerator again. Where do I need to place the PagingControl.js file in order for the require('PagingControl'); to work.

I get an error that it could not find the module.

Thanks!

// This code is not working, could you please help me.. if says message = "Can't find variable: PagingControl";
var win = Ti.UI.createWindow();

var view1 = Ti.UI.createView({
backgroundColor : '#123'
});
var view2 = Ti.UI.createView({
backgroundColor : '#246'
});
var view3 = Ti.UI.createView({
backgroundColor : '#48b'
});

var sView = Ti.UI.createScrollableView({

backgroundColor : 'gray',
opacity : 0.8,
showPagingControl : false,
top : 20,
width : 280,
height : 350,
views : [view1, view2, view3],
currentPage : 0,
pagingControlColor : 'transparent'

});

if (sView && sView.views && sView.views.length > 0) {
require('PagingControl');
var sViewPagingControl = new PagingControl(sView);
sView.add(sViewPagingControl);
window.add(sView);
}

win.add(sView);
win.open();

As the previous person said, this code wouldn't work on iOS.

require('PagingControl');
var sViewPagingControl = new PagingControl(sView);

change to:

var PagingControl = require('PagingControl');
var sViewPagingControl = new PagingControl(sView);

Fixes that issue, then it can't find a lot of variables, so I just quickly made them all global.

Then who knows where it put the new paging control, so I didn't use the example of adding it to the scrollableView itself, but to my main window, underneath the scrollview.

Then it worked, although it flashes a lot during scrolling.
So changed the listener to scrollEnd, instead of Sroll. But it ultimately did work on iOS, after some changes.
