SFML Window not responding to inputs - c++

Question

I recently started working on SFML. I just created a window then later started to separating my main code. First i wrote a window class.
Nothing special, just draws my window and prints mouse coordinates.
#include "Window.hpp"
#include <iostream>
Window::Window()
{
SetWindow(800,600, "JUST SFML");
}
void Window::SetWindow(unsigned int width, unsigned int height, sf::String title)
{
m_sfmlWindow.create(sf::VideoMode(width, height), title);
}
void Window::StartDrawing()
{
m_sfmlWindow.clear();
}
void Window::EndDrawing()
{
m_sfmlWindow.display();
}
bool Window::isClosed()
{
return !m_sfmlWindow.isOpen();
}
void Window::EventControl()
{
sf::Event event;
while (m_sfmlWindow.pollEvent(event))
{
if (event.type == sf::Event::Closed)
{
m_sfmlWindow.close();
}
if (event.type == sf::Event::MouseMoved)
{
std::cout << event.mouseMove.x << " , " << event.mouseMove.y << std::endl;
}
}
}
void Window::Draw(sf::Drawable& shape)
{
m_sfmlWindow.draw(shape);
}
Everything worked perfectly.
Then i tought i need a GameManager class that i can just use in my main class.
#include "GameManager.hpp"
GameManager::GameManager()
{
m_shape.setRadius(30.0f);
m_shape.setFillColor(sf::Color::Magenta);
m_incVal = 1.0f;
m_posX = 10.0f;
m_frameRate = 1.0f / 60.0f;
}
GameManager::~GameManager()
{
}
void GameManager::InputControl()
{
if (sf::Keyboard::isKeyPressed(sf::Keyboard::Right))
{
m_incVal = 1.0f;
}
if (sf::Keyboard::isKeyPressed(sf::Keyboard::Left))
{
m_incVal = -1.0f;
}
}
void GameManager::UpdateScene()
{
if (m_deltaTime.asSeconds() >= m_frameRate)
{
m_posX += m_incVal;
m_shape.setPosition(m_posX, 300);
m_deltaTime -= sf::seconds(m_frameRate);
}
}
void GameManager::DrawScene()
{
m_window.StartDrawing();
m_window.Draw(m_shape);
m_window.EndDrawing();
}
void GameManager::RestartClock()
{
m_deltaTime += m_clock.restart();
}
bool GameManager::isFinished()
{
return m_window.isClosed();
}
It was perfectly working when i use window object, later i've changed to gamemanager it start being not responding.. I can get keyboard inputs but not mouse move coordinates. Where am i make it wrong?
#include <SFML/Graphics.hpp>
#include "GameManager.hpp"
#include "Window.hpp"
int main()
{
GameManager gameManager;
while (!gameManager.isFinished())
{
gameManager.InputControl();
gameManager.UpdateScene();
gameManager.DrawScene();
gameManager.RestartClock();
}
/*
sf::CircleShape shape(100.0f);
shape.setFillColor(sf::Color::Magenta);
shape.setOutlineThickness(5.0f);
shape.setOutlineColor(sf::Color::White);
Window window;
while (!window.isClosed())
{
window.EventControl();
window.StartDrawing();
window.Draw(shape);
window.EndDrawing();
}
*/
return 0;
}

In order to receive events (such as the mouse moving), you need to call pollEvents on the window.
In your commented code, you were doing this through your Window::EventControl() method. Your new GameManager class isn't calling this, however, so you aren't receiving any events.
