|

62 | \class QScriptValue
|
---|
63 |
|
---|
64 | \brief The QScriptValue class acts as a container for the Qt Script data types.
|
---|
65 |
|
---|
66 | \ingroup script
|
---|
67 | \mainclass
|
---|
68 |
|
---|
69 | QScriptValue supports the types defined in the \l{ECMA-262}
|
---|
70 | standard: The primitive types, which are Undefined, Null, Boolean,
|
---|
71 | Number, and String; and the Object type. Additionally, Qt Script
|
---|
72 | has built-in support for QVariant, QObject and QMetaObject.
|
---|
73 |
|
---|
74 | For the object-based types (including Date and RegExp), use the
|
---|
75 | newT() functions in QScriptEngine (e.g. QScriptEngine::newObject())
|
---|
76 | to create a QScriptValue of the desired type. For the primitive types,
|
---|
77 | use one of the QScriptValue constructor overloads.
|
---|
78 |
|
---|
79 | The methods named isT() (e.g. isBool(), isUndefined()) can be
|
---|
80 | used to test if a value is of a certain type. The methods named
|
---|
81 | toT() (e.g. toBool(), toString()) can be used to convert a
|
---|
82 | QScriptValue to another type. You can also use the generic
|
---|
83 | qscriptvalue_cast() function.
|
---|
84 |
|
---|
85 | Object values have zero or more properties which are themselves
|
---|
86 | QScriptValues. Use setProperty() to set a property of an object, and
|
---|
87 | call property() to retrieve the value of a property.
|
---|
88 |
|
---|
89 | \snippet doc/src/snippets/code/src_script_qscriptvalue.cpp 0
|
---|
90 |
|
---|
91 | Each property can have a set of attributes; these are specified as
|
---|
92 | the third (optional) argument to setProperty(). The attributes of a
|
---|
93 | property can be queried by calling the propertyFlags() function. The
|
---|
94 | following code snippet creates a property that cannot be modified by
|
---|
95 | script code:
|
---|
96 |
|
---|
97 | \snippet doc/src/snippets/code/src_script_qscriptvalue.cpp 1
|
---|
98 |
|
---|
99 | If you want to iterate over the properties of a script object, use
|
---|
100 | the QScriptValueIterator class.
