◆ queryProperty()

QScriptClass::QueryFlags QDeclarativeGlobalScriptClass::queryProperty	(	const QScriptValue &	object,
		const QScriptString &	name,
		QueryFlags	flags,
		uint *	id
	)

virtual

Queries this script class for how access to the property with the given name of the given object should be handled.

The given flags specify the aspects of interest. This function should return a subset of flags to indicate which aspects of property access should be further handled by the script class.

For example, if the flags contain HandlesReadAccess, and you would like your class to handle the reading of the property (through the property() function), the returned flags should include HandlesReadAccess. If the returned flags do not contain HandlesReadAccess, the property will be handled as a normal script object property.

You can optionally use the id argument to store a value that will subsequently be passed on to functions such as property() and setProperty().

The default implementation of this function returns 0.

Note: This function is only called if the given property isn't already a normal property of the object. For example, say you advertise that you want to handle read access to property foo, but not write access; if foo is then assigned a value, it will become a normal script object property, and subsequently you will no longer be queried regarding read access to foo.

     Q_UNUSED(object);
     Q_UNUSED(name);
     Q_UNUSED(flags);
     Q_UNUSED(id);
     return HandlesWriteAccess;
 }

◆ setProperty()

void QDeclarativeGlobalScriptClass::setProperty	(	QScriptValue &	object,
		const QScriptString &	name,
		uint	id,
		const QScriptValue &	value
	)

virtual

Sets the property with the given name of the given object to the given value.

The id argument is only useful if you assigned a value to it in queryProperty().

The default implementation does nothing.

An invalid value represents a request to remove the property.
