Getting window width and heigth with MLX_MAXIMIZED

[ocxpke]

Is there any way to get those values without needing to initializing the main monitor and taking those parameters with glfw3???

If I understand you I think you want ?
https://github.com/codam-coding-college/MLX42/blob/master/src/mlx_monitor.c

This can be executed prior to mlx_init / glfwInit

Exactly, window width and height had the values of mlx_init despite being initialized with MLX_MAXIMIZED
Thx 😊

The function mlx_get_monitor_size() does not work prior to mlx_init() as far as I can tell.
I want to use the monitor width and height to make a full screen window.

Case 1: get monitor size before mlx_init()

int	init_window(
		t_window *window)
{
	uint32_t	width;
	uint32_t	height;
	uint32_t	monitor_count;

	// glfwInit();

	GLFWmonitor** monitors = glfwGetMonitors(&monitor_count); // found in mlx_get_monitor_size()
	mlx_get_monitor_size(0, &width, &height); // id 0-2 tested, two monitors connected

	printf("(%d, %d, %d)\n", monitor_count, width, height); // always (0, 0, 0)

	mlx_set_setting(MLX_STRETCH_IMAGE, true);
	mlx_set_setting(MLX_FULLSCREEN, true);

	window->mlx = mlx_init(width, height, WINDOW_TITLE, false);
	if (window->mlx == NULL)
		return (mlx_errno);
	return (0);
}

This does not work, it always fails, monitor count, width and height always equal 0.
Issue seems to be that get_monitor_size() fails, because this function relies on glfwInit() to be completed:

	int32_t monitor_count;
	GLFWmonitor** monitors = glfwGetMonitors(&monitor_count);
	if (index > monitor_count || !monitors)
		return;

glfwGetMonitors() fails when executed before glfwInit().

Solution for now: call glfwInit() yourself before mlx_get_monitor_size() and mlx_init().
Alternatively call mlx_get_monitor_size() and mlx_resize() after mlx_init().

Calling just mlx_get_monitor_size() after mlx_init() works fine and was what I needed thx :D
