Struct WindowConfig 

pub struct WindowConfig { /* private fields */ }

Declarative configuration for an operating-system window.

Apply it with WindowModifierExt::window to render a composable subtree in a separate OS window on desktop. Platforms without native sub-window support render the content inline, so pointer input and other composable behavior stay shared. Two configurations compare equal when they ask the same of the window; their callbacks are not compared.

Implementations

impl WindowConfig

pub fn new(title: impl Into<String>, width: f32, height: f32) -> Self

Creates a decorated, resizable window with a fixed initial content size.

pub fn new_for_state(title: impl Into<String>, state: WindowState) -> Self

Creates a decorated, resizable window using a remembered state size.

pub fn borderless(title: impl Into<String>, width: f32, height: f32) -> Self

Creates a borderless, non-resizable window with a fixed initial content size.

pub fn borderless_for_state( title: impl Into<String>, state: WindowState, ) -> Self

Creates a borderless, non-resizable window using a remembered state size.

pub fn with_position(self, x: f32, y: f32) -> Self

Sets the initial outer-window position in logical screen coordinates.

pub fn with_host_window_position(self, x: f32, y: f32) -> Self

Sets the initial outer-window position relative to the host application window.

pub fn with_transparent(self, transparent: bool) -> Self

Sets whether compositor transparency should be requested.

pub fn with_shadow(self, shadow: bool) -> Self

Sets whether the desktop draws its own drop shadow behind the window.

The desktop takes the shadow’s shape from the window’s alpha, which suits a window whose edges are hard. A window that fades out, a glow or a blur, gets a contour drawn where the desktop’s threshold falls, and turns the shadow off to draw its own.

pub fn with_resizable(self, resizable: bool) -> Self

Sets whether the operating system should allow interactive resizing.

pub fn with_visible(self, visible: bool) -> Self

Sets whether the window should be visible when created.

pub fn with_always_on_top(self, always_on_top: bool) -> Self

Sets whether the window should be kept above normal windows.

pub fn with_focus(self, focus: WindowFocus) -> Self

Sets whether the window takes focus when it is created. See WindowFocus.

pub fn with_min_size(self, width: f32, height: f32) -> Self

Sets the minimum content size in logical pixels.

pub fn with_max_size(self, width: f32, height: f32) -> Self

Sets the maximum content size in logical pixels.

pub fn on_moved(self, callback: impl Fn(f32, f32) + 'static) -> Self

Called when the operating system reports an external outer-window move.

Position changes requested through WindowState are acknowledged by the desktop host without re-entering this callback.

pub fn on_resized(self, callback: impl Fn(f32, f32) + 'static) -> Self

Called when the operating system reports a new content size.

pub fn on_close_requested(self, callback: impl Fn() + 'static) -> Self

Called when the operating system requests that this window close.

pub fn with_state(self, state: WindowState) -> Self

Binds this configuration to a remembered WindowState.

The current state supplies the requested position and size. The desktop window host keeps the state in sync with the operating system unless an explicit callback updates it first.
