@mrjj Yes, it worked. Thank you!

as it already suggested by other in the group, please go through signals/slots. Try few examples with how signals/slots work. This should give good info to achieve your use case.

@Massimiliano No, you do not drop it in your app directory! You just need to call it in a terminal window and pass the path to your binary as parameter. Please read the documentation:
"The tool can be found in QTDIR/bin/windeployqt. It takes an .exe file or a directory that contains an .exe file as an argument, and scans the executable for dependencies."
