I am creating a personal SFML GUI library, but I have ran into an error, and I can't find any place online to fix it. In the main file, I am creating a panel and pushing buttons onto it. All the sizing is working correctly to be on screen and are out putted in the console. I am then drawing the panel which should be drawing the buttons, but that function is not activating. Please, how do I fix this?
main
int main()
{
sf::RenderWindow window(sf::VideoMode(800, 600), "SFMin");
sfm::Button button([]() {std::cout << "Hello World" << std::endl;}, "test");
sfm::Button button2([]() {std::cout << "Hello World" << std::endl;}, "really really long name for testing purposes only");
sfm::Panel panel(sfm::Layouts::LIST);
panel.pushBackElement(button);
panel.pushBackElement(button2);
while (window.isOpen())
{
sfm::RegionCoordinates<sf::Vector2f> windowArea(sf::Vector2f(0.0f, 0.0f), sf::Vector2f(window.getSize().x, window.getSize().y));
// ----------------polling----------------
sf::Event event;
while (window.pollEvent(event))
{
if (event.type == sf::Event::Closed)
{
window.close();
}
if (event.type == sf::Event::Resized)
{
sf::FloatRect visibleArea(0, 0, event.size.width, event.size.height);
window.setView(sf::View(visibleArea));
window.setSize(sf::Vector2u(event.size.width, event.size.height));
}
}
// ----------------update----------------
panel.update(windowArea, &window);
window.clear(sf::Color::White);
// ----------------draw----------------
panel.draw(windowArea, &window);
window.display();
}
return 0;
