Struct RiverLayoutV3 

pub struct RiverLayoutV3 { /* private fields */ }

receive and respond to layout demands

This interface allows clients to receive layout demands from the compositor for a specific output and subsequently propose positions and dimensions of individual views.

See Event for the list of possible events.

Implementations

impl RiverLayoutV3

pub fn destroy<D>(self, conn: &mut Connection<D>)

destroy the river_layout_v3 object

This request indicates that the client will not use the river_layout_v3 object any more.

Since version 1.

pub fn push_view_dimensions<D>( self, conn: &mut Connection<D>, x: i32, y: i32, width: u32, height: u32, serial: u32, )

propose dimensions of the next view

This request proposes a size and position for a view in the layout demand with matching serial.

A client must send this request for every view that is part of the layout demand. The number of views in the layout is given by the view_count argument of the layout_demand event. Pushing too many or too few view dimensions is a protocol error.

The x and y coordinates are relative to the usable area of the output, with (0,0) as the top left corner.

Since version 1.

pub fn commit<D>( self, conn: &mut Connection<D>, layout_name: CString, serial: u32, )

commit a layout

This request indicates that the client is done pushing dimensions and the compositor may apply the layout. This completes the layout demand with matching serial, any other requests sent with the serial are a protocol error.

The layout_name argument is a user-facing name or short description of the layout that is being committed. The compositor may for example display this on a status bar, though what exactly is done with it is left to the compositor’s discretion.

The compositor is free to use this proposed layout however it chooses, including ignoring it.

Since version 1.

impl Ord for RiverLayoutV3

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

impl PartialEq<ObjectId> for RiverLayoutV3

fn eq(&self, other: &ObjectId) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialEq<RiverLayoutV3> for ObjectId

fn eq(&self, other: &RiverLayoutV3) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialEq for RiverLayoutV3

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for RiverLayoutV3

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
