Struct gdk4_wayland::WaylandToplevel [−][src]
pub struct WaylandToplevel(_);Expand description
The Wayland implementation of gdk::Toplevel.
Beyond the gdk::Toplevel API, the Wayland implementation
has API to set up cross-process parent-child relationships between
surfaces with export_handle() and
set_transient_for_exported().
Implements
[WaylandSurfaceExt][trait@crate::prelude::WaylandSurfaceExt], gdk::prelude::SurfaceExt, gdk::prelude::ToplevelExt, WaylandSurfaceExtManual
Implementations
Asynchronously obtains a handle for a surface that can be passed to other processes.
When the handle has been obtained, callback will be called.
It is an error to call this function on a surface that is already exported.
When the handle is no longer needed, unexport_handle()
should be called to clean up resources.
The main purpose for obtaining a handle is to mark a surface
from another surface as transient for this one, see
set_transient_for_exported().
Note that this API depends on an unstable Wayland protocol, and thus may require changes in the future.
callback
callback to call with the handle
Returns
true if the handle has been requested, false if
an error occurred.
Marks self as transient for the surface to which the given
parent_handle_str refers.
Typically, the handle will originate from a
export_handle() call in another process.
Note that this API depends on an unstable Wayland protocol, and thus may require changes in the future.
parent_handle_str
an exported handle for a surface
Returns
true if the surface has been marked as transient,
false if an error occurred.
Destroys the handle that was obtained with
export_handle().
It is an error to call this function on a surface that does not have a handle.
Note that this API depends on an unstable Wayland protocol, and thus may require changes in the future.

Tries to cast to an object of type T. This handles upcasting, downcasting

runtime, while downcast and upcast will do many checks at compile-time already. Read more
