#[repr(transparent)]pub struct Display { /* private fields */ }
Expand description
Display
objects are the GDK representation of a workstation.
Their purpose are two-fold:
- To manage and provide information about input devices (pointers, keyboards, etc)
- To manage and provide information about output devices (monitors, projectors, etc)
Most of the input device handling has been factored out into separate
Seat
objects. Every display has a one or more seats, which
can be accessed with DisplayExt::default_seat()
and
DisplayExt::list_seats()
.
Output devices are represented by Monitor
objects, which can
be accessed with DisplayExt::monitor_at_surface()
and similar APIs.
Properties
composited
true
if the display properly composites the alpha channel.
Readable
input-shapes
true
if the display supports input shapes.
Readable
rgba
true
if the display supports an alpha channel.
Readable
Signals
closed
Emitted when the connection to the windowing system for @display is closed.
opened
Emitted when the connection to the windowing system for @display is opened.
seat-added
Emitted whenever a new seat is made known to the windowing system.
seat-removed
Emitted whenever a seat is removed by the windowing system.
setting-changed
Emitted whenever a setting changes its value.
