Graphics / Blinking Functionality to the Cursor

« on: April 03, 2021, 06:49:13 pm »

I have created a Typing Class that displays keyboard events onto an SFML window. I am not trying to create a Cursor class that will show a blinking cursor onto the same SFML window.
My thinking is to have the addEventHandler function read the mouse input, then the actual blinking occurs in my update function. I want the blinking to occur every 500ms, I'm stuck on what else I need to make the blinking occur on the SFML window. Thanks in advance.

class Cursor : public sf::Drawable{
public:
    Cursor();
    void addEventHandler(sf::RenderWindow& window, sf::Event event);
    void update();
    virtual void draw(sf::RenderTarget& window, sf::RenderStates states) const;


private:
    sf::Cursor cursor;
    sf::Clock clock;
    bool showCursor;
    const sf::Time delay;

};
 

////////////////////Cursor.cpp//////////////////////////
#include "Cursor.h"

Cursor::Cursor(){
}

void Cursor::addEventHandler(sf::RenderWindow &window, sf::Event event) {
    if(event.type == sf::Event::MouseButtonPressed)
    {
        std::cout << "Mouse" << std::endl;
        if (cursor.loadFromSystem(sf::Cursor::Arrow)){
            window.setMouseCursor(cursor);
            window.setMouseCursorVisible(true);
        }
    }
}

void Cursor::update() {
    if(clock.getElapsedTime() >= sf::milliseconds(500))
    {
        clock.restart();
        cursor.loadFromSystem(sf::Cursor::Arrow);
        std::cout<<"Update"<<std::endl;
    }
}

void Cursor::draw(sf::RenderTarget &window, sf::RenderStates states) const {

}
 

////////////////////main.cpp//////////////////////////
#include <iostream>
#include "SFML/Graphics.hpp"

int main() {
    sf::RenderWindow window;
    window.create(sf::VideoMode(800,600), "Typing in SFML");
    Typing typing;

    while (window.isOpen())
    {
        sf::Event event;
        while (window.pollEvent(event))
        {
            if(event.type == sf::Event::Closed)
            {
                window.close();
            }
            typing.addEventHandler(window, event);
            cursor.addEventHandler(window, event);
        }
        cursor.update();
        typing.update();
        window.clear();
        window.draw(typing);
        window.draw(cursor);
