Detailed Description

Used internally by the Value class as the base class for its shared value objects.

The Value class is essentially a reference-counted pointer to a shared instance of a ValueSource object. If you're feeling adventurous, you can create your own custom ValueSource classes to allow Value objects to represent your own custom data items.

~ValueSource()

Member Function Documentation

getValue()

virtual var Value::ValueSource::getValue ( ) const

pure virtual

Returns the current value of this object.

setValue()

virtual void Value::ValueSource::setValue ( const var & newValue )

pure virtual

Changes the current value.

This must also trigger a change message if the value actually changes.

sendChangeMessage()

void Value::ValueSource::sendChangeMessage

(

bool

dispatchSynchronously

)

Delivers a change message to all the listeners that are registered with this value.

If dispatchSynchronously is true, the method will call all the listeners before returning; otherwise it'll dispatch a message and make the call later.
