Constant SDL_HINT_VIDEO_WAYLAND_MODE_SCALING

pub const SDL_HINT_VIDEO_WAYLAND_MODE_SCALING: *const i8 = _; // {alloc40015<imm>: *const i8}
Available on crate feature dep_sdl3 only.
Expand description

A variable controlling how modes with a non-native aspect ratio are displayed under Wayland.

When this hint is set, the requested scaling will be used when displaying fullscreen video modes that don’t match the display’s native aspect ratio. This is contingent on compositor viewport support.

The variable can be set to the following values:

  • “aspect” - Video modes will be displayed scaled, in their proper aspect ratio, with black bars.
  • “stretch” - Video modes will be scaled to fill the entire display. (default)
  • “none” - Video modes will be displayed as 1:1 with no scaling.

This hint should be set before creating a window.

§Availability

This hint is available since SDL 3.2.0.
