I want to create my own signal ie. i want to create the pushbutton click which will activate when pushbutton will click. I know that there is already the signal for that. But i want to create my own to know how custom signal is define. Is it possible to do that as i have heard that these signals are emitted from the system. Also, Can we create our own mouse event? I want to create my own so that it will work on embedded linux as multitouch is still making problem there.
