Problem with MouseButtonPressed

[Romsik788]

I have code

if (event.type == Event::MouseButtonPressed)
        {
            if (event.key.code == Mouse::Left)
            {
                  //Some code
            }
        }

I need that when long hold down the left mouse button this code does not work. (When you click on the mouse, this code should work once, while further holding mouse down, the code should not work) How to do it?
P.S. Sorry my english

Your code is incorrect. Instead of this:

if (event.key.code == Mouse::Left)

You should do this:

if (event.mouseButton.button == Mouse::Left)

event.key.code is for keyboard events.

Fixed, but this still did not solve my problem

I fixed the problem, it was necessary to put this code in the event loop. As a result, I have this:

Event event;
while(window.pollEvent(event))
        {
            if (event.type == Event::Closed)
                {
                    window.close();
                }
            if (event.type == Event::MouseButtonPressed)
                {
                    if (event.mouseButton.button == Mouse::Left)
                        {
                            //Some code
                        }
                }
         }
