Graphics / Text Input - Handling press of backspace.

« on: June 15, 2012, 01:19:14 am »

I've been messing around with this for a while, and I'm having a bit of trouble getting this to work. I'm trying to write a simple text input system using sf::Text and sf::String, and nothing I've tried has gotten it to handle pressing backspace.

Here is my code:

#include <SFML/Graphics.hpp>
#include <string>
#include <iostream>
using namespace std;

int main()
{
    sf::RenderWindow App(sf::VideoMode(800, 600), "SFML Text Input System");
    sf::String Text;
    string str;

    const sf::Input & Input = App.GetInput();

    while(App.IsOpened())
    {
        sf::Event Event;
        while(App.GetEvent(Event))
        {
            if (Event.Type == sf::Event::Closed) App.Close();
            if (Event.Type == sf::Event::TextEntered)
            {
                if (Event.Text.Unicode < 128)
                    str += static_cast<char>(Event.Text.Unicode);
            }
            Text.SetText(str);
        }

        App.Clear();
        App.Draw(Text);
        App.Display();
    }
}
 

Any help is greatly appreciated.
