Text entered but update when keyreleased
« on: May 11, 2013, 02:10:26 pm »
Hi there I'm working on a textbox where the user enters its name. The problem I'm having is that a soon as i press a key it writes out the character about five times in a row. That's why I just want it to enter a character when the user releases the key.

if(mainEvent.type == sf::Event::TextEntered)
        {      
                char c = static_cast<char>(mainEvent.text.unicode);
                if(c >= 'A' && c <= 'z')
                {
                        // Add the new character to the string
                        str = c;
                        // Set the string to name
                        nameString += str;

                                name.setString(nameString);
                                cout << nameString;
                       
                }
        }

Thanks in advance :)

If you really only want 1 character each KeyPressed you could use "window.setKeyRepeatEnabled(false);"

But normally sf::Event::TextEntered return the character only once and when you hold the key longer than (i guess 1second) it will start "spamming" the character, like every Windows Inputbox does.

Can you show the surrounding code? The complete event loop would be great (I don't care about other events, I just want to see how/where your code block is executed).

Can you show the calling code? I'd like to see where the event instance comes from.

Ok, let's be more explicit. The event instance is initialized by a call to window.pollEvent. I want to see this call, and what happens to the event until it reaches userInput ;)

Any usage of mainEvent should happen inside the event loop. Outside, its contents are undefined, or if it has a wider scope, it will always be the last event that happened repeating again and again -- which explains your problem.
