SFML 3 how to deal with texts within a rectangle

Question

#pragma once

#include <SFML/Graphics.hpp>
class RectangleWText
{
private:
    sf::RectangleShape shape;
    sf::Font font;
    sf::Text label(std::string&);

public:
    RectangleWText(const sf::Vector2f& size, const sf::Vector2f& position, const 
std::string& text = "", const std::string& fontPath = "fonts/verdana.ttf") {
    
    if (!font.openFromFile("verdana.ttf"))
    {
        std::cerr << "Error loading font" << std::endl;
    }
    sf::Font font(fontPath);
    sf::Text label(font);


    shape.setSize(size);
    shape.setPosition(position);

    label.setString(text);
    label.setPosition(position);
}

void draw(sf::RenderWindow& window) {
    window.draw(shape);
    window.draw(label); 
}
};

SFML 3 changed the way you initiate text and it is killing me since I can't draw it in my draw function now, I am new to SFML please someone help me.

Have you checked the tutorial? sfml-dev.org/tutorials/3.0/graphics/text and documentation sfml-dev.org/documentation/3.0.0/classsf_1_1Text.html - SFML is quite well documented and the tutorials are rather good. The actual source code github.com/SFML/SFML/blob/master/src/SFML/Graphics/Text.cpp is also quite readable. — Jesper Juhl

Default constructor of sf::Text was removed in SFML3.0. Now one have to initialize text with sf::Font object.

You can create a font instance before creating your RectangleWText and pass a font's reference to constructor. In this case you'll be able to properly create label member this manner

RectangleWText(const sf::Vector2f& position, const sf::Font& _font, const std::string& text = "", /* other parameters */) :
  label{_font}
{
    ...
    
    label.setString(text);
    label.setPosition(position);
}
