Windows Resize is acting weird
« on: December 11, 2021, 09:51:56 pm »
So I wanted to use SFML Graphics to make kind of a menu for something I have to do at college. I do want to say that I am new to this and I don't know a lot about SFML.
In the first picture you can see that everything looks good but after I resize it, everything goes bad... The positions of the squares and their sizes are based on the window size so I have no clue why it looks like that.

Here is my code, sorry if it is long and that a few variables and name functions are written in Romanian and not in English.
#include <SFML/Graphics.hpp>
#include <string>
#include <iostream>
#include <fstream>
using namespace std;
float lungime_start;
float latime_start;
float lungime_finish;
float latime_finish;
float inaltime_input;
float inaltime_output;
float lungime_input;
float lungime_output;
float lungime_max_trapez;
float lungime_min_trapez;
float inaltime_trapez;
float lungime_conditie;
float MarimeText;
sf::Color culoare = sf::Color(159,39,9);
sf::Color outline = sf::Color(85,24,9);
sf::Color CuloareText = sf::Color(255,255,255);
sf::Color CuloareLinii = sf::Color(8,228,237);
sf::Color CuloareMeniuButoane = sf::Color(30,9,121);
sf::Color CuloareBackground = sf::Color(9, 70, 121);
sf::RectangleShape Instructiuni(sf::Vector2f(1.f,1.f));
sf::RectangleShape Meniu1(sf::Vector2f(1.f, 1.f));
sf::RectangleShape Meniu2(sf::Vector2f(1.f, 1.f));
sf::RectangleShape Meniu3(sf::Vector2f(1.f, 1.f));
sf::RectangleShape GenerareCod(sf::Vector2f(1.f, 1.f));

When you resize your window, you want to adjust the view, either to show more or to scale appropriately.
