Usage
Widget common usage is pretty simple. It reacts on App custom events:
refreshStartWorking
refreshStopWorking
So you just need to fire these custom events on app, when you need start or stop the refresh animation:
Ti.App.fireEvent('refreshStartWorking') //to start widget animation
Ti.App.fireEvent('refreshStopWorking') //to stop widget animation
Extended Usage
I tried to make it like gmail android app pull-to-refresh, so if you want to show user the growing bar when content pulling down, you need to set some globals in your app You can look in alloy.js file and see this globals. To make the bar growing you need to fire custom event pullDown And if user stop pulling down before edge fire event pullEnd I didn't want to do difficult calculations of pull pixels in each touchmove event, so I used a discrete increment and discrete edge of starting refresh widget
Alloy.Globals.pullHeight
Alloy.Globals.pullIncrementor
The working logic of these globals is nearly simple, so you can download repo and watch this logic inside of your Titanium Studio
Finally
The main point of usage of this widget is to fire events in your app, so do it carefully. Don't forget to disable touch event or may be button(or something else you use to fire event) to prevent invalid events firing I added an defence code into widget to prevent refresh animation doubling but you can make your own defence in app. Any styles may to be changed in tss files.
