how to find the mouse position in the window sfml in c - c

Question

im trying to just make a button in the middle of the screen but i cant check if the mouse is inside the sfRectangleShape
sfRectangleShape* newButton(sfVector2f size, sfVector2f position, sfColor color)
{
sfRectangleShape *newButton;
newButton = sfRectangleShape_create();
sfRectangleShape_setSize(newButton, size);
sfRectangleShape_setOrigin(newButton, (sfVector2f){sfRectangleShape_getSize(newButton).x / 2, sfRectangleShape_getSize(newButton).y / 2});
sfRectangleShape_setFillColor(newButton, color);
sfRectangleShape_setPosition(newButton, position);
return newButton;
}
int main()
{
sfRenderWindow* window;
sfView *view = sfView_create();
window = sfRenderWindow_create((sfVideoMode){600, 400, 32}, "", sfResize | sfClose, NULL);
sfRectangleShape *screenButton = newButton((sfVector2f){100, 35}, (sfVector2f){300, 200}, rgba(72, 74, 89));
sfVector2i mouse_pos;
while (sfRenderWindow_isOpen(window))
{
sfRenderWindow_mapPixelToCoords(window, mouse_pos, view);
sfEvent event;
while (sfRenderWindow_pollEvent(window, &event))
{
/* Close window : exit */
if (event.type == sfEvtClosed)
sfRenderWindow_close(window);
}
printf("%d, %d", mouse_pos.x, mouse_pos.y);
sfRenderWindow_clear(window, sfColor_fromRGBA(82, 84, 100, 1));
sfRenderWindow_drawRectangleShape(window, screenButton, NULL);
sfRenderWindow_display(window);
}
return 0;
}
i cant find a example or a tutorial that teach how to detect if my mouse are inside the sfRectangleShape and the function sfRenderWindow_mapPixelToCoords just return the number -40270372832704

Answer 1

You could use sfMouse_getPosition(window) to get the mouse coordinates, which returns as sfVector2i

Answer 2

As Kolbjørn Christiansen said you can use sfMouse_getPosition(window) to get the position of the mouse on your window (not screen. if you want screen you have to remove window from the function arg: sfMouse_getPosition()).
I want to add that this function returns a vector 2f, which is an object containing x and y coords. You can also use with accordance to this the globalbounds function contains to see if that coord is inside that object, a full workup of the solution would be:
sf::RectangleShape rect;
//init rect sizes position etc.
//...
if (rect.getGlobalBounds().contains(sf::Mouse::getPosition(window).x, sf::Mouse::getPosition(window).y))
{
//means mouse is in rect
}
else
{
//mouse is not in rect
}
