Represents a local or remote address. To create a new Url (or assign to an existing one), use the following syntax:

var url = new Url("")</code>

Read-only properties:
* ''string'' '''toString''': the URL as a String object

Read-write properties (each representing a portion of the full URL):
* ''string'' '''protocol'''
* ''string'' '''host'''
* ''string'' '''path'''
* ''string'' '''user'''
* ''string'' '''password'''

= ByteArray =
This class provides an array of bytes. This is often used by data centric objects, such as the Job classes returned by getUrl.

Read-only properties:
* ''number'' '''length''': the size of the array (number of bytes)

* '''chop(number numBytes)''': chops numBytes from the end of the array
* ''bool'' '''equals(ByteArray other)'''
* ''ByteArray '''left(number len)''': return len bytes from the left of the array
* ''ByteArray '''mid(number pos, number len)''': returns an array of bytes starting a post and length len (if len is -1, it returns all remaining bytes)
* ''ByteArray '''remove(number pos, number len)''': removes len bytes starting at index pos from the array and returns it
* ''ByteArray '''right(number len)''': returns len bytes from the right of the array
* ''ByteArray '''simplified()''': returns a byte array that has whitespace removed from the start and the end, and which has each sequence of internal whitespace replaced with a single space
* ''ByteArray '''toBase64()''': returns the array encoded in base64
* ''ByteArray '''toLower()''': returns a lowercased copy of the array
* ''ByteArray '''toUpper()''': returns an uppercased copy of the array
* ''ByteArray '''trimmed()''': returns a copy of the array with whitespace remove from the start and end
* truncate(number pos): truncates the array at index pos
* ''String'' '''toLatin1String()''': returns a Latin1-ized string based on the array
* ''String'' '''toUtf8()''': (API v3) returns a string from the contents of the array using a Utf8 conversation
* ''String'' '''valueOf()''': returns the raw data in the array as a string

= GraphicsItem =
This class represents an item on the canvas. Support is only provided so that GraphicsItem objects returned or taken by other objects work. There is no meaningful API provided directly in the JavaScript runtime for these objects and they should not need to be used directly.

= QSizePolicy =
The QSizePolicy class is a layout attribute describing horizontal and vertical resizing policy. This can be set on any graphics widget that you have using the enums provided for this (QtSizePolicy ), for example:

button = new PushButton();
button.sizePolicy = QSizePolicy(QSizePolicyMaximum, QSizePolicyFixed);

This is useful when your widgets are being laid out by a layout (specially the anchor layout).

* ''QtSizePolicy '' '''horizontalPolicy''': The horizontal component of the size policy.
* ''QtSizePolicy '' '''verticalPolicy''': The vertical component of the size policy.
* ''number'' '''horizontalStretch''': The horizontal stretch factor of the size policy.
* ''number'' '''verticalStretch''': The vertical stretch factor of the size policy.
