Qt Code: 
  1. void VSDPM_CDT::DisplaySimWnd(int nModule)
  2. {
  3. 	emit moduleDatarcvd(nModule);
  4. }
To copy to clipboard, switch view to plain text mode 

Here i am emitting a signal i.e n module and at receiver side:
Qt Code: 
  1. connect (this, SIGNAL(moduleDatarcvd(int)), this, SLOT(ShowModuleSimWnd(int)),Qt::BlockingQueuedConnection);
To copy to clipboard, switch view to plain text mode 

and my ShowmoduleSimWnd is a method which will be called when it is received a signal i.e

Qt Code: 
  1. void VSDPM_CDT::ShowModuleSimWnd(int nModule)
  2. {
  3. 	if(nModule == 0)
  4. 	{
  5. 		OnClickCanSimulation();
  6. 	}
  7. 	else if(nModule == 1)
  8. 	{
  9. 		OnClickLinSimulation();
  10. 	}
  11. 	else if(nModule == 2)
  12. 	{
  13. 		OnClickADCSimulation();
  14. 	}
  15. 	else if(nModule == 3)
  16. 	{
  17. 		OnClickDIOSimulation();
  18. 	}
  19. 	else if(nModule == 4)
  20. 	{
  21. 		OnClickPWMSimulation();
  22. 	}
  23. 	else if(nModule == 5)
  24. 	{
  25. 		ShowLogMessage("test","Inside module");
  26. 		OnClickTCPIPSimulation();
  27. 	}
  28. 	else if(nModule == 6)
  29. 	{
  30. 		OnClickBTSimulation();
  31. 	}
  32. }
To copy to clipboard, switch view to plain text mode 

in lin if(nModule == 5) i am getting a problem. Actually i am blocking the queue here to wait for a signal to come. please help me in this scenario
