This is a revamp of the Titanium TandemScroll module.
You can lock a number of ScrollViews or ScrollableViews together and proportionally scroll them. I've added a X,Y parallaxFactor, that allows you to play with the amount of scrolling.
This is an iOS only module
Download the latest distribution ZIP-file and consult the Titanium Documentation on how install it, or simply use the gitTio CLI:
$ gittio install co.coolelephant.tandemscroll
var win = Ti.UI.createWindow({
backgroundColor: '#fff'
});
var TandemScroll = require('co.coolelephant.tandemscroll');
var scrollViews = [];
for (var i = 0; i < 3; i++) {
var scrollView = Ti.UI.createScrollView({
contentWidth: 1000 * (i + 1),
contentHeight: 1000 * (i + 1)
});
scrollView.add(Ti.UI.createLabel({
text: 'I am Scroll View ' + i,
width: 160, height: 30,
top: 200 + 70 * i, left: 200 + 40 * i
}));
scrollViews.push(scrollView);
win.add(scrollView);
}
TandemScroll.lockTogether({
views: scrollViews
});
scrollViews[scrollViews.length-1].addEventListener('scroll', function (evt) {
Ti.API.info(evt.x + ',' + evt.y);
});
win.open();
There is a ScrollableView demo included with the module that shows how this could be used for an application introduction screen.
