Question

I am using qt, I am wondering is it possible set double press Esc shortcut? I want to have an effect, when I press Esc twice, a function is called.

Thanks

Answer 1

on each pressing ESC make

PRESSED+=1;

and if on any next press

     if (PRESSED >=2) {
        //fire event here
        ...
        // Dont forget to reset PRESSED for next usage
       PRESSED=0;
      }

in case PRESSED yet not equals "2" (if user pressed it once) after 1-3 seconds reset it to 0; and fire event for single press.

for the situation when u dont want fire SinglePressEvent in case doublepress just delay singlepress event for 1-2 seconds to wait for second press.. if second press does not appear fire singlepressevent.
