General / String erase problem while using Event::TextEntered

« on: March 20, 2022, 06:00:23 pm »

#include <SFML/Graphics.hpp>
#include <iostream>

using namespace std;
using namespace sf;

int main()
{
    Keyboard keyboard;

    RenderWindow window( VideoMode( 800, 600 ), "..." );

    string help;

    while( window.isOpen() )
    {
        Event event;

        while( window.pollEvent( event ) )
        {
            if( event.type == Event::Closed )
                window.close();

            if( event.type == Event::KeyPressed && keyboard.isKeyPressed( Keyboard::Backspace ) )
            {
                help.erase( help.end() - 1 );
                cout << help << endl;
            }
            else if ( event.type == Event::TextEntered && event.text.unicode < 128 )
            {
                help += static_cast<char>(event.text.unicode);
                cout << help << endl;
            }
        }

        window.display();
    }

    return 0;
}
 

Try running it, type anything you would like and try to use backspace. Used once works good, but if i try to delete second character then nothing changes in my string. How to solve this?
