Struct Panel 

pub struct Panel { /* private fields */ }

Desktop panel state.

Implementations

impl Panel

pub fn new(screen_width: u32, screen_height: u32) -> Self

Create a new panel for the given screen dimensions.

pub fn y(&self) -> i32

Get the Y coordinate of the panel (bottom of screen).

pub fn init_layer_surface(&mut self) -> Option<u32>

Initialize the layer-shell surface for the panel.

This creates a layer-shell surface anchored to the bottom edge of the output with an exclusive zone equal to the panel height. The compositor will reserve this space and prevent normal windows from overlapping.

Returns the layer surface ID, or None if already initialized.

pub fn layer_surface_id(&self) -> Option<u32>

Get the layer-shell surface ID.

pub fn set_active_workspace(&self, index: usize)

Set the active workspace.

pub fn active_workspace(&self) -> usize

Get the active workspace index.

pub fn update_workspace_counts(&self)

Update workspace window counts from the window manager.

pub fn update_buttons(&self)

Update the panel button list from the window manager.

pub fn update_clock(&self)

Update the clock display with real wall-clock date and time.

pub fn handle_click(&self, x: i32, _y: i32) -> Option<WindowId>

Handle a click on the panel.

Returns the window ID that should be focused, if any.

pub fn render(&self, buf: &mut [u8])

Render the panel into a pixel buffer.

The buffer is assumed to be screen_width * PANEL_HEIGHT * 4 bytes (BGRA format). Renders workspace indicators, window buttons, and the date/time clock.
