Hi to all
I am making GUI using QT3.3. Through GUI I am invoking a process using QProcess.
I want to send SIGINT(cntl+C) signal to that process.How can I send through GUI.
Can any one help me?

Well, in unix environment you can allways use:

kill(pid_of_process,SIGINT)

kill(pid_of_process,SIGINT)

To copy to clipboard, switch view to plain text mode 

Of course you need to make appropriate includes (unistd.h and signals.h I think).
