Precentage in setSize or setPosition does nothing

[Sandorex]

I downloaded TGUI 2.7.6 for SFML 2.4.2 and 100% in setSize, setPosition doesn't work, the element dissapears

im compiling on windows 10 using msbuild project made by cmake

my code:

#include <cstdio>
#include <iostream>
#include <TGUI/TGUI.hpp>
#include "about.h"


int main(int argc, char *argv[])
{
    sf::RenderWindow window(sf::VideoMode(800, 600), "APP " VERSION_STRING);
    tgui::Gui gui(window);

    sf::Image img;
    img.loadFromFile("icon.png");
    window.setIcon(img.getSize().x, img.getSize().y, img.getPixelsPtr());

    auto button = tgui::Button::create("Click me!");
    button->setPosition({"50.0", "25.0"});
    gui.add(button);


    auto picture = tgui::Picture::create("icon.png");
    picture->setSize({"100%", "100%"});
    gui.add(picture);


    window.setFramerateLimit(80);
    
    while (window.isOpen())
    {
        sf::Event event;

        while (window.pollEvent(event))
        {
            if (event.type == sf::Event::Closed)
                window.close();
            else if (event.type == sf::Event::Resized)
            {
                window.setView(sf::View(sf::FloatRect(0, 0, (float)event.size.width, (float)event.size.height)));
                gui.setView(window.getView());
            }
            gui.handleEvent(event);
        }

        window.clear();
        gui.draw();
        window.display();
    }

    return 0;
}

What TGUI version are you using, 0.7 or 0.8?
This may happen is you are using 0.7, as using "100%" is something that only works in 0.8.
