Window Manager

Implementations

impl WindowManager

pub fn new() -> Self

Create a new window manager

pub fn create_window( &self, x: i32, y: i32, width: u32, height: u32, owner_pid: u64, ) -> Result<WindowId, KernelError>

Create a new window

pub fn destroy_window(&self, window_id: WindowId) -> Result<(), KernelError>

Destroy a window

pub fn move_window( &self, window_id: WindowId, x: i32, y: i32, ) -> Result<(), KernelError>

Move a window

pub fn resize_window( &self, window_id: WindowId, width: u32, height: u32, ) -> Result<(), KernelError>

Resize a window

pub fn focus_window(&self, window_id: WindowId) -> Result<(), KernelError>

Focus a window

pub fn window_at_position(&self, x: i32, y: i32) -> Option<WindowId>

Get window at position

pub fn process_input(&self, event: InputEvent)

Process input event

pub fn queue_event(&self, event: WindowEvent)

Queue an event for delivery

pub fn get_events(&self, window_id: WindowId) -> Vec<InputEvent>

Get pending events for a window

pub fn set_window_title(&self, window_id: WindowId, title: &str)

Set a window’s title.

pub fn get_window(&self, window_id: WindowId) -> Option<Window>

Get a clone of a window by ID.

pub fn get_focused_window_id(&self) -> Option<WindowId>

Get the currently focused window ID.

pub fn get_all_windows(&self) -> Vec<Window>

Get all windows

pub fn get_visible_windows(&self) -> Vec<Window>

Get all visible windows on the active workspace, ordered by z-order (bottom to top – last element is the topmost window).

pub fn set_screen_size(&self, width: u32, height: u32)

Set the screen dimensions (called when display is configured)

pub fn set_placement_heuristic(&self, heuristic: PlacementHeuristic)

Set the window placement heuristic

pub fn place_window(&self, window_id: WindowId) -> (i32, i32)

Compute the placement position for a window based on the current heuristic.

The window must already be inserted into self.windows so its dimensions can be read. Returns (x, y) for the top-left corner.

pub fn snap_window(&self, window_id: WindowId, zone: SnapZone)

Snap a window to a screen zone (half, quarter, or maximize).

Saves the window’s current geometry so it can be restored later.

pub fn detect_snap_zone( x: i32, y: i32, screen_w: u32, screen_h: u32, ) -> SnapZone

Detect which snap zone a screen coordinate falls in.

Returns SnapZone::None if the position is not within the edge threshold (8 pixels).

pub fn tile_windows(&self, layout: TileLayout)

Tile all visible windows on the active workspace using the given layout.

pub fn set_window_opacity(&self, window_id: WindowId, opacity: u8)

Set window opacity (0 = transparent, 255 = opaque)

pub fn switch_workspace(&self, workspace_id: WorkspaceId)

Switch to a different workspace.

pub fn move_window_to_workspace( &self, window_id: WindowId, workspace_id: WorkspaceId, )

Move a window to a different workspace.

pub fn get_active_workspace(&self) -> WorkspaceId

Get the currently active workspace ID.

pub fn get_workspace_windows(&self, workspace_id: WorkspaceId) -> Vec<WindowId>

Get the list of window IDs on a given workspace.

pub fn event_loop_iteration(&self)

Event loop iteration

Trait Implementations

impl Default for WindowManager

fn default() -> Self

Returns the “default value” for a type.
