QML的property支持的类型[感慨文]

今天在QML里面写了这么一句

property QTime secords然后出错QTime is not a type 烦恼啊烦恼，文档里面不是说支持的么===========================================================================Supported data types

Any C++ data that is used from QML - whether as custom properties, or parameters for signals or functions - must be of a type that is recognizable by QML.

By default, QML recognizes the following data types:

• bool
• unsigned int, int
• float, double, qreal
• , , 
• , 
• , 
• , 
• , 
• *
• Enumerations declared with ()

To allow a custom C++ type to be created or used in QML, the C++ class must be registered as a QML type using(), as shown in the  section above.

=====================================================================================================真烦人，Nokia是骗纸，最后又看见文档一个关于QML的property所支持的类型===================================================================================================== Supported property types

All QML properties are typed. The examples above show properties with int and string types; notice that the type of the property must be declared. The type is used to determine the property behavior, and how the property is defined in C++.

A number of property types are supported by default. These are listed in the table below, with their default values and the corresponding C++ type:

QML Type Name	Default value	C++ Type Name
	0	int
	false	bool
	0.0	double
	0.0	double
	"" (empty string)
	"" (empty url)
	#000000 (black)
	undefined
	undefined

===============================================================原来大多数类型在QML中都有替代品，少数没有的写入QML仍然提示XXXX is not a type不过基本常用的类型都有了，可以满足日常需要了，剩下日后再研究
