Struct runa_wayland_protocols::stable::xdg_shell::xdg_toplevel::v5::requests::SetParent

pub struct SetParent {
    pub parent: Object,
}

set the parent of this surface

Set the “parent” of this surface. This surface should be stacked above the parent surface and all other ancestor surfaces.

Parent surfaces should be set on dialogs, toolboxes, or other “auxiliary” surfaces, so that the parent is raised when the dialog is raised.

Setting a null parent for a child surface unsets its parent. Setting a null parent for a surface which currently has no parent is a no-op.

Only mapped surfaces can have child surfaces. Setting a parent which is not mapped is equivalent to setting a null parent. If a surface becomes unmapped, its children’s parent is set to the parent of the now-unmapped surface. If the now-unmapped surface has no parent, its children’s parent is unset. If the now-unmapped surface becomes mapped again, its parent-child relationship is not restored.

The parent toplevel must not be one of the child toplevel’s descendants, and the parent must be different from the child toplevel, otherwise the invalid_parent protocol error is raised.

Implementations

impl SetParent

pub const OPCODE: u16 = 1u16

Trait Implementations

impl Clone for SetParent

fn clone(&self) -> SetParent

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SetParent

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> Deserialize<'a> for SetParent

fn deserialize(data: &'a [u8], fds: &'a [RawFd]) -> Result<Self, Error>

Deserialize from the given buffer. Returns deserialized message, and number of bytes and file descriptors consumed, respectively.

impl PartialEq<SetParent> for SetParent

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for SetParent

fn serialize<Fds: Extend<OwnedFd>>(self, buf: &mut BytesMut, fds: &mut Fds)

Serialize into the buffered writer. This function returns no errors, failures in seializing are generally program errors, and triggers panicking.

fn len(&self) -> u16

How many bytes will this message serialize to. Including the 8 byte header.

fn nfds(&self) -> u8

How many file descriptors will this message serialize to.
