Events

There are on and un methods for responding to server commands or interacting with a page widget. Via these methods, subscribing and unsubscribing from widget events is performed.

An example of interaction with events:

var onRender = function () {
    sitephone.show();
};
//subscribe to an event
sitephone.on('render', onRender);
//Unsubscribe from an event
sitephone.un('render', onRender);

Cancelling method calls via events before{methodName}

There are events that precede a method calls:

- beforeshow
- beforehide
- beforedestroy
- beforerender

If you return these events in an explicit form false in a processor, methods of the same will not be called

Example:

sitephone.on('beforeshow', function () {
    return !customWidget.isVisible();
});
sitephone.show();

In this example, the show method will not be called if the processor returns false.
