[SOLVED]Is there any system(application) variable which keeps track of whether the application is being used first time

[adnan]

I wan't to display a message, only on the first usage of application, i.e. a piece of code should be executed only once, when application is first time invoked. I tried using QSettings, but couldn't work out any way.

@
if(firstTime)
{
//do something!
}

No, but you can store information about first startup in QSettings. Learn about it in documentation.
