Implementations

impl WindowLayout

pub const fn empty() -> Self

Create an empty layout.

pub fn single(window: Window) -> Self

Create a layout with one window.

pub fn add(&mut self, window: Window)

Add a window to the layout.

If this is the first window, it becomes active.

pub fn active(&self) -> Option<&Window>

Get the active window.

If no window is explicitly active but windows exist, returns the first window. This ensures a valid window is always available when the layout is non-empty.

pub fn active_mut(&mut self) -> Option<&mut Window>

Get the active window mutably.

If no window is explicitly active but windows exist, returns the first window. This ensures a valid window is always available when the layout is non-empty.

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

Get the active window ID.

pub fn set_active(&mut self, id: WindowId) -> bool

Set the active window by ID.

Returns true if the window was found and made active.

pub const fn is_empty(&self) -> bool

Check if the layout is empty.

pub const fn len(&self) -> usize

Get the number of windows.

pub fn clear(&mut self)

Clear all windows from the layout.

pub fn get(&self, id: WindowId) -> Option<&Window>

Get window by ID.

pub fn get_mut(&mut self, id: WindowId) -> Option<&mut Window>

Get window by ID mutably.

pub fn remove(&mut self, id: WindowId) -> bool

Remove a window by ID (#474).

Returns true if the window was found and removed. If the removed window was active, the active index is adjusted.
