TAlfPointCommand Class Reference

class TAlfPointCommand : public TAlfObjectCommand

TAlfPointCommand is a command that operates on a timed point. Usage:

        //Create timed point command to set visual size
   TAlfRealPoint p1( 0.1, 0.1 );
   TAlfPointCommand command1( iVisual, EAlfValueCommandVisualSize, p1, 1 );
  
  //Send command , Primary image will be set
   iEnv->Send( command, 1 );

Constructor & Destructor Documentation

TAlfPointCommand(TAny *, TAlfPointCommandTarget, TAlfOp)

IMPORT_C	TAlfPointCommand	(	TAny *	aObject,
			TAlfPointCommandTarget	aObjectType,
			TAlfOp	aOperation
		)

Constructs a new timed point command.

Parameters

TAny * aObject	Object. Needs to match with aObjectType
TAlfPointCommandTarget aObjectType	Timed value to modify.
TAlfOp aOperation	Operation to perform.

TAlfPointCommand(TAny *, TAlfPointCommandTarget, TAlfRealPoint, TInt, TParameterTarget)

IMPORT_C	TAlfPointCommand	(	TAny *	aObject,
			TAlfPointCommandTarget	aObjectType,
			TAlfRealPoint	aTarget,
			TInt	aTransitionTime = 0,
			TParameterTarget	aParameterTarget = EBoth
		)

Constructs a new timed point command.

Parameters

TAny * aObject	Object. Needs to match with aObjectType
TAlfPointCommandTarget aObjectType	Timed value to modify.
TAlfRealPoint aTarget	Target value
TInt aTransitionTime = 0	Time (in milliseconds) for the transition to occur.
TParameterTarget aParameterTarget = EBoth

TAlfPointCommand(TAny *, TAlfPointCommandTarget, TAlfOp, TAlfRealPoint, TReal32, TParameterTarget)

IMPORT_C	TAlfPointCommand	(	TAny *	aObject,
