Struct XdgToplevelIconManagerV1 

pub struct XdgToplevelIconManagerV1 { /* private fields */ }

interface to manage toplevel icons

This interface allows clients to create toplevel window icons and set them on toplevel windows to be displayed to the user.

See also the Request enum for this interface.

Implementations

impl XdgToplevelIconManagerV1

pub fn icon_size(&self, size: i32)

describes a supported & preferred icon size

This event indicates an icon size the compositor prefers to be available if the client has scalable icons and can render to any size.

When the ‘xdg_toplevel_icon_manager_v1’ object is created, the compositor may send one or more ‘icon_size’ events to describe the list of preferred icon sizes. If the compositor has no size preference, it may not send any ‘icon_size’ event, and it is up to the client to decide a suitable icon size.

A sequence of ‘icon_size’ events must be finished with a ‘done’ event. If the compositor has no size preferences, it must still send the ‘done’ event, without any preceding ‘icon_size’ events.

pub fn done(&self)

all information has been sent

This event is sent after all ‘icon_size’ events have been sent.

impl PartialEq<Weak<XdgToplevelIconManagerV1>> for XdgToplevelIconManagerV1

fn eq(&self, other: &Weak<XdgToplevelIconManagerV1>) -> 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.
