Interface for defining the drawing of decorations

A type implementing this trait can be used to define custom decorations additionnaly to the ones provided by this crate and be used with Window.

Associated Types

type Error

Type of errors that may occur when attempting to create a frame

type Config

Configuration for this frame

Required methods

fn init(
    base_surface: &WlSurface,
    compositor: &Attached<WlCompositor>,
    subcompositor: &Attached<WlSubcompositor>,
    shm: &Attached<WlShm>,
    theme_manager: Option<ThemeManager>,
    callback: Box<dyn FnMut(FrameRequest, u32, DispatchData<'_>)>
) -> Result<Self, Self::Error>

Initialize the Frame.

Providing non None to theme_manager should prevent Frame to theme pointer over base_surface surface.

fn set_states(&mut self, states: &[State]) -> bool

Set the Window XDG states for the frame

This notably includes information about whether the window is maximized, active, or tiled, and can affect the way decorations are drawn.

Calling this should not trigger a redraw, but return true if a redraw is needed.

fn set_hidden(&mut self, hidden: bool)

Hide or show the decorations

Calling this should not trigger a redraw

fn set_resizable(&mut self, resizable: bool)

Set whether interactive resize hints should be displayed and reacted to

fn new_seat(&mut self, seat: &Attached<WlSeat>)

Notify that a new wl_seat should be handled

This seat is guaranteed to have pointer capability

fn remove_seat(&mut self, seat: &WlSeat)

Notify that this seat has lost the pointer capability or has been lost

fn resize(&mut self, newsize: (u32, u32))

Change the size of the decorations

Calling this should not trigger a redraw

fn redraw(&mut self)

Redraw the decorations

fn subtract_borders(&self, width: i32, height: i32) -> (i32, i32)

Subtracts the border dimensions from the given dimensions.

fn add_borders(&self, width: i32, height: i32) -> (i32, i32)

Adds the border dimensions to the given dimensions.

fn set_config(&mut self, config: Self::Config)

Sets the configuration for the frame

fn set_title(&mut self, title: String)

Sets the frames title

Provided methods

fn location(&self) -> (i32, i32)

Returns the coordinates of the top-left corner of the borders relative to the content

Values should thus be negative
