Struct WindowOptions 

pub struct WindowOptions {

    pub title: String,
    pub initial_logical_size: Size,
    pub size_policy: WindowSizePolicy,
    pub minimum_logical_size: Option<Size>,
    pub maximum_logical_size: Option<Size>,
    pub resizable: bool,
    pub visible: bool,
    pub decorations: bool,
    pub transparency_mode: TransparencyMode,
    pub background_color: Color,
    pub maximized: bool,
    pub fullscreen: Option<Fullscreen>,
    pub window_level: WindowLevel,
    pub window_icon: Option<WindowIcon>,
}

Configuration used when creating an Incular desktop window.

All sizes are logical pixels. A transparent window is a strict presentation request: a backend must either configure compatible compositor alpha or report that the request is unsupported rather than silently presenting an opaque/black surface.

Fields

title: String

initial_logical_size: Size

size_policy: WindowSizePolicy

Selects whether native viewport metrics or retained content own size.

In WindowSizePolicy::Content mode initial_logical_size is also the minimum content viewport. The framework follows the retained root’s layout size and can shrink back when primary content becomes smaller. Paint-only overflow such as shadows and transient overlays does not resize the native host. This is deliberately independent of window decorations.

minimum_logical_size: Option<Size>

maximum_logical_size: Option<Size>

resizable: bool

visible: bool

decorations: bool

transparency_mode: TransparencyMode

background_color: Color

Base scene color. This does not change native compositor transparency.

maximized: bool

fullscreen: Option<Fullscreen>

window_level: WindowLevel

window_icon: Option<WindowIcon>

Implementations

impl WindowOptions

pub fn new(title: impl Into<String>) -> Self

pub fn validate(&self) -> Result<(), WindowOptionsError>

Checks size constraints before a native adapter attempts window creation.

pub fn requested_state( &self, ) -> Result<WindowRequestedState, LogicalSizeLimitsError>
