pub struct Device { /* private fields */ }
Expand description
The Device
object represents an input device, such
as a keyboard, a mouse, or a touchpad.
See the Seat
documentation for more information
about the various kinds of devices, and their relationships.
This is an Abstract Base Class, you cannot instantiate it.
§Properties
§caps-lock-state
Whether Caps Lock is on.
This is only relevant for keyboard devices.
Readable
§direction
The direction of the current layout.
This is only relevant for keyboard devices.
Readable
§display
The Display
the Device
pertains to.
Readable | Writeable | Construct Only
§has-bidi-layouts
Whether the device has both right-to-left and left-to-right layouts.
This is only relevant for keyboard devices.
Readable
§has-cursor
Whether the device is represented by a cursor on the screen.
Readable | Writeable | Construct Only
§modifier-state
The current modifier state of the device.
This is only relevant for keyboard devices.
Readable
§n-axes
Number of axes in the device.
Readable
§name
The device name.
Readable | Writeable | Construct Only
§num-lock-state
Whether Num Lock is on.
This is only relevant for keyboard devices.
Readable
§num-touches
The maximal number of concurrent touches on a touch device.
Will be 0 if the device is not a touch device or if the number of touches is unknown.
Readable | Writeable | Construct Only
§product-id
Product ID of this device.
Readable | Writeable | Construct Only
§scroll-lock-state
Whether Scroll Lock is on.
This is only relevant for keyboard devices.
Readable
§seat
Seat
of this device.
Readable | Writeable
§source
Source type for the device.
Readable | Writeable | Construct Only
§tool
The DeviceTool
that is currently used with this device.
Readable
§vendor-id
Vendor ID of this device.
Readable | Writeable | Construct Only
§Signals
§changed
Emitted either when the number of either axes or keys changes.
On X11 this will normally happen when the physical device routing events through the logical device changes (for example, user switches from the USB mouse to a tablet); in that case the logical device will change to reflect the axes and keys on the new physical device.
§tool-changed
Emitted on pen/eraser devices whenever tools enter or leave proximity.
§Implements
GLib type: GObject with reference counted clone semantics.
