What is an Event

Last Updated: Feb 14, 2017 11:01AM EST
Events are Central



An Event is a trigger.
A Tap is a classic UI event.
For example the Image Block has a Tap Event.
When a user tap the image you can use the Tap Event to trigger an Action.

An Action is triggered by an Event.
There are a lots of actions in EachScape from a 'Switch to another view' to move from one view to another to
'Post to Facebook ' or 'Tweet' or 'Get GPS Location'
 

Everything in EachScape relies on Actions triggered by Events.


Events and Actions are tightly linked together.

Type of Events 

Event are triggered at 3 different levels:

Where the Event is triggered depends on the nature of the Event.
It is up to the EachScape developer to handle the Event appropriately.
 

  • App Level Events are triggered anytime and available throughout the app.
 
  • View Level Events are View related Events like an Orientation Change or a shake, they need to be addressed at the View Level.
 
  • Block Level Events are related to a Block like, a Tap Action, they depends of the nature of the Block.
