QML Basic Types
QML has a set of primitive types, as listed below, that are used throughout the QML Elements.
|
The action type has all the properties of QAction. | |
|
A boolean is a binary true/false value. | |
|
A color is a standard color name in quotes. | |
|
A date is specified as "YYYY-MM-DD". | |
|
A double number has a decimal point and is stored in double precision. | |
|
An enumeration type consists of a set of named values. | |
|
A font type has the properties of a QFont. | |
|
An integer is a whole number, e.g. 0, 10, or -20. | |
|
A list of objects. | |
|
A point type has x and y attributes. | |
|
A real number has a decimal point, e.g. 1.2 or -29.8. | |
|
A rect type has x, y, width and height attributes. | |
|
A size type has width and height attributes | |
|
A string is a free form text in quotes, e.g. "Hello world!". | |
|
A time is specified as "hh:mm:ss". | |
|
A URL is a resource locator, like a file name. | |
|
A variant type is a generic property type. | |
|
A vector3d type has x, y, and z attributes. |
To create additional types, such as data types created in C++, read the Extending QML Functionalities using C++ article.

Not all basic types can be declared as property types
The “basic types” listed in the QML documentation are types that are encountered in QML (might be e.g. as a return value from a C++ function, for example), but not all of them can currently be declared as property types within QML (the list of supported types is much smaller, and is currently available here [doc.qt.nokia.com].
