# Overview

The process pool associated with a web view is specified by its web view configuration. Each web view is given its own Web Content process until an implementation-defined process limit is reached; after that, web views with the same process pool end up sharing Web Content processes. Process pools do not take arguments, just pass the same reference to multiple web views.

E.g.

var pool = Ti.UI.iOS.createWebViewProcessPool();

var config1 = Ti.UI.iOS.createWebViewConfiguration({
    processPool: pool
});

var config2 = Ti.UI.iOS.createWebViewConfiguration({
    processPool: pool
});

var firstWebView = Ti.UI.createWebView({
    top: 0,
    height: 250,
    configuration: config1,
    url: 'https://www.google.com'
});
var secondWebView = Ti.UI.createWebView({
    top: 250,
    configuration: config2,
    url: 'https://www.apple.com/'
});
var window = Ti.UI.createWindow();
window.add(firstWebView);
window.add(secondWebView);
window.open();

# Properties

# apiName READONLY

Availability
8.0.0
9.2.0
apiName :String

The name of the API that this proxy corresponds to.

The value of this property is the fully qualified name of the API. For example, Titanium.UI.Button returns Ti.UI.Button.

# bubbleParent

Availability
8.0.0
9.2.0
bubbleParent :Boolean

Indicates if the proxy will bubble an event to its parent.

Some proxies (most commonly views) have a relationship to other proxies, often established by the add() method. For example, for a button added to a window, a click event on the button would bubble up to the window. Other common parents are table sections to their rows, table views to their sections, and scrollable views to their views. Set this property to false to disable the bubbling to the proxy's parent.

Default: true

# fireEvent

# removeEventListener

Availability
8.0.0
9.2.0
removeEventListener(name, callback) → void

Removes the specified callback as an event listener for the named event.

Multiple listeners can be registered for the same event, so the callback parameter is used to determine which listener to remove.

When adding a listener, you must save a reference to the callback function in order to remove the listener later:

var listener = function() { Ti.API.info("Event listener called."); }
window.addEventListener('click', listener);

To remove the listener, pass in a reference to the callback function:

window.removeEventListener('click', listener);

Parameters

Name Type Description
name String

Name of the event.

callback Callback<Titanium.Event>

Callback function to remove. Must be the same function passed to addEventListener.

Returns

Type
void
