Como criar instâncias

Utilize o método "WSCbase::getNewInstance()".

  char*     class_name = "WSCvlabel";
  char*     obj_name   = "vlabel001";
  WSCbase*  parent  //The parent instance which has new instance.

  //create a new instance.
  WSCbase* object = WSCbase::getNewInstance(class_name,parent,obj_name);
  object->initialize(); //initialize the instance.
  object->clear();           

  object->setProperty(WSNx,100);
  object->setProperty(WSNy,100);
  object->setProperty(WSNwidth,100);
  object->setProperty(WSNheight,100);
  object->setVisible(True);

  

You have to call initialize() to initialize before calling the other methods of the created instance.

Como deletar instâncias

Utilize WSGFdestroyWindow().

  //destroy the instance.
  WSGFdestroyWindow(object);

  

Não chame "WSGFdestroyWindow()" com o mesmo name duas vêzes, e não tente acessar uma instância distruída, porque gerará "fatal memory error" (erro fatal de memória).
