Controlling infinite loop with button click - Qt

ankurt44

Consider I have two buttons "start" and "end", and a slot "start_game()". The method "start_game()" looks like:

void start_game()
{
       //an infinite loop that refreshes(re-paints) a widget
       while(/*some flag maybe*/)
       {
                 //update paint widget
                 //exit when "end" button is clicked
       }
}

I can easily connect "clicked(bool)" signal of the "start" button with above method containing infinite loop. I could not understand how can I control this loop, for example I want to exit this loop on "end" button's click. I understand that the loop blocks the main event loop. What is the efficient wat of getting such functionality.

Hi and welcome to devnet,

Since your comment is update paint widget, why do you need such a loop ?
