For those who are too lazy to look into attachment, here is code present in the constructor of base object:
Qt Code: 
  1. setObjectName("trial");
  2.     editor = 0;
  3.  
  4.     qsProject = new QSProject(this);
  5.  
  6.     m_pButton1 = new QPushButton("First", this);
  7.     m_pButton2 = new QPushButton("Second", this);
  8.     m_pButton2->move(20, 0);
  9.     m_pButton1->setObjectName("button");
  10.     m_pButton2->setObjectName("buttons");
  11.  
  12.  
  13.     widget = new MyWidget(this, qsProject);
  14.     widget->setObjectName("container_");
  15.     widget->resize(50, 50);
  16.     widget->move(50, 50);
  17.  
  18.     m_pLabel1 = new MyLabel(this);
  19.     m_pLabel1->setText("Hello World!");
  20.     m_pLabel1->move(100, 100);
  21.  
  22.     m_pLabel2 = new MyLabel(this);
  23.     m_pLabel2->setText("Are You Listning?");
  24.     m_pLabel2->move(100, 105);
  25.  
  26.     resize( 200, 200);
  27.  
  28. //     qsProject->addObject(m_pButton1);
  29. //     qsProject->addObject(m_pButton2);
  30. //     qsProject->addObject(widget);
  31.     qsProject->addObject(this);
  32.  
  33.     editor = new ScriptEditor( qsProject );
  34.     editor->show();
