class simvx.graphics.platform._glfw.GlfwBackend

WindowBackend implementation using GLFW.

Initialization

supports_gamepads

True

create_window(width: int, height: int, title: str, *, visible: bool = True) → None

create_graphics_surface(instance: Any) → Any

get_required_instance_extensions() → list[str]

poll_events() → None

should_close() → bool

get_framebuffer_size() → tuple[int, int]

get_window_size() → tuple[int, int]

set_title(title: str) → None

get_content_scale() → tuple[float, float]

set_key_callback(callback: collections.abc.Callable[[int, int, int], None] | None) → None

set_mouse_button_callback(callback: collections.abc.Callable[[int, int, int], None] | None) → None

set_cursor_pos_callback(callback: collections.abc.Callable[[float, float], None] | None) → None

set_scroll_callback(callback: collections.abc.Callable[[float, float], None] | None) → None

set_char_callback(callback: collections.abc.Callable[[int], None] | None) → None

set_resize_callback(callback: collections.abc.Callable[[int, int], None] | None) → None

set_cursor_shape(shape: int) → None

Set cursor shape. 0=arrow, 1=ibeam, 2=crosshair, 3=hand, 4=hresize, 5=vresize.

set_mouse_capture(mode: int) → None

Apply a MouseCaptureMode int (0=visible, 1=hidden, 2=captured, 3=confined) to the OS cursor.

CURSOR_DISABLED (captured) keeps reporting growing virtual cursor positions, so the existing position-diff mouse_delta path stays correct without any delta change.

get_cursor_pos() → tuple[float, float]

poll_gamepads() → list[tuple[int, dict[str, bool], dict[str, float]]]

Poll all connected gamepads. Returns list of (id, buttons, axes).

GLFW reports both sticks and both triggers as -1..1, so a resting trigger arrives as -1.0; :func:gamepad.normalise_axes maps that onto the engine’s 0..1.

set_window_size(width: int, height: int) → None

request_close() → None

Signal the window to close at the next poll_events cycle.

set_fullscreen(fullscreen: bool) → None

Toggle fullscreen mode. Stores windowed position/size for restore.

is_fullscreen() → bool

destroy() → None
