Pushbutton gui to glow LED



  • I have a simple cpp program to glow an external led on Beaglebone Black, now I need to do the same through a pushbutton on gui, can i do it by making a function containing my program and calling it through signal and slot, or if anyone have any other way to do it then please help. Thanks in advance.



  • Sure. Depending on your program you could turn it into a Qt class and have one of its functions work as a slot that is signalled by the pushbutton, or you could have the slot in your UI code and call from that your app which is basically just renamed: main(arcg, argv) -> led_function(arcg, argv)
