[mythtv] Function() to stop a playing movie?

[Suchit Rout, Noida]

Hi Group,
 
Please note this is my first email to the you.
Kindly excuse any violations ;)
 
I have been studying the code of mythtv for a while now.
I understand that while a movie is being played in mythfrontend, a loop in tv_play.cpp gets on executing.
 
While a movie is being played, if I press the "Esc" button, the movie stops playing and MythTV returns to the screen where we have
 
     * Watch Recodings
     * etc etc
 
Now, what I wanna do is simulate this "Esc pressing" with the help of a single function call that can cause the movie to stop and make MythTV return to the above mentioned screen. Due to my poor knowledge in QT I am unable to solve the problem in hand.
 
Can anyone help me figure this out?
 
I would like to run a thread alongwith the RunMainLoop (if i am correct) in tv_play.cpp that wuold keep on checking for some signal (not exactly signal per se, it could be a change in value in a database table etc). the moment I detect that change, my function is called and the movie play stops, making MythTV to return to the abov screen.
 
 
 
Regards,
sr
