Qml數據類型

整體上，qml的數據類型分爲基本數據類型和對象類型，基本類型用於表示簡單的值，其中一部分由qml語言提供，另外一部分來自qml模塊。

qml對象類型指類的實例，又分爲qml對象類型和javascript對象，qml引擎支持幾乎全部的javascript標準對象

1、基本數據類型

1.1 qml提供的基本數據類型

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模塊提供的基本類型

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

 

2、對象類型

2.1 qml對象類型

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
Instantiator	Dynamically creates objects
Timer	Triggers a handler at a specified interval
