Hi,

Thank you very much for reply, I know that it can be done in a single shot thread , but as I told you this is not final design its just for PoC, main idea is to know how to switch screens.

I have changed the code as per your suggestion, but still I see only one ui screen all the time, below is the code:


Qt Code: 
  1. Base::Base()
  2. {
  3.        qDebug() << "Base CTOR called\n";
  4.  
  5.        this->lrsGUI = new RaptorLrsGUI;
  6.        this->lrsGUI->setlabel(QString("Loading Status..."));         
  7.        this->coreGUI = new RaptorCoreGUI;
  8.  
  9.        this->stackedWidget = new QStackedWidget();
  10.        this->setCentralWidget(this->stackedWidget);
  11.        this->stackedWidget->addWidget(this->lrsGUI);
  12.        this->stackedWidget->addWidget(this->coreGUI);
  13.  
  14.        this->stackedWidget->setCurrentIndex(0);
  15.  
  16. }
  17.  
  18. /* SLOT Fn */
  19. void Base::rcvInitData()
  20. { 
  21.     this->stackedWidget->setCurrentIndex(1);
  22. }
