总体上，qml的数据类型分为基本数据类型和对象类型，基本类型用于表示简单的值，其中一部分由qml语言提供，另一部分来自qml模块。

qml对象类型指类的实例，又分为qml对象类型和javascript对象，qml引擎支持几乎所有的javascript标准对象

一、基本数据类型

1.1 qml提供的基本数据类型

bool	Binary true/false value
double	Number with a decimal point, stored in double precision
enumeration	Named enumeration value
int	Whole number, e.g. 0, 10, or -20
list	List of QML objects
real	Number with a decimal point
string	Free form text string
url	Resource locator
var	Generic property type

 

1.2 qml模块提供的基本类型

date	Date value
point	Value with x and y attributes
rect	Value with x, y, width and height attributes
size	Value with width and height attributes
color	ARGB color value. The type refers to an ARGB color value. It can be specified in a number of ways:
font	Font value with the properties of QFont. The type refers to a font value with the properties of QFont
matrix4x4	A matrix4x4 type is a 4-row and 4-column matrix
quaternion	A quaternion type has scalar, x, y, and z attributes
vector2d	A vector2d type has x and y attributes
vector3d	Value with x, y, and z attributes
vector4d	A vector4d type has x, y, z and w attributes

 

二、对象类型

2.1 qml对象类型

Date	Provides date functions
Number	Object provides represents a number value
String	Object represents a string value
Component	Encapsulates a QML component definition
Qt	Provides a global object with useful enums and functions from Qt
QtObject	A basic QML type
Locale	Provides locale specific properties and formatted data
Binding	Enables the arbitrary creation of property bindings
Connections	Describes generalized connections to signals
