Options for configuring the headless platform.

Fields

fps: i32

Gets or sets the number of frames per second at which the renderer should run. Default 60.

should_render_on_ui_thread: bool

Render directly on the UI thread instead of using a dedicated render thread. This can be usable if your device doesn’t have multiple cores to begin with. This setting is true by default (the documentation of the original says false).

use_headless_drawing: bool

Gets or sets a value indicating whether to use headless drawing mode, which allows rendering without creating an actual window.

Disable this option if you are using the Skia backend or another drawing backend.

frame_buffer_format: PixelFormat

Gets or sets the pixel format to be used for the headless window framebuffers.

overlay_popups: bool

Embeds popups to the window when set to true. The default value is true.

use_shared_mouse_device: Option<bool>

Shares a single mouse device between all top-levels when set to true, so that pointer capture and click counting are global rather than per-window, as they are on the other platforms. When None or false, every top-level gets its own mouse device.

supports_window_positioning: bool

When false, top-level windows always report a PixelPoint origin position and ignore moves, as on Wayland where the compositor owns window placement. Popups still report their position relative to their parent. The default value is true.

use_logical_desktop_coordinates: bool

When true, desktop scaling is always 1 and screen coordinates (window position, point_to_screen, point_to_client) are logical units regardless of render scaling, as on macOS and Wayland. The default value is false: screen coordinates are physical pixels, as on Windows and X11.
