38 * @GDK_EXTENSION_EVENTS_NONE: no extension events are desired.

41 * will be displayed for the device.

44 * are desired for a particular widget.

55 * @GDK_SOURCE_MOUSE: the device is a mouse. (This will be reported for the core
56 * pointer, even if it is something else, such as a trackball.)
57 * @GDK_SOURCE_PEN: the device is a stylus of a graphics tablet or similar device.
58 * @GDK_SOURCE_ERASER: the device is an eraser. Typically, this would be the other end
59 * of a stylus on a graphics tablet.
60 * @GDK_SOURCE_CURSOR: the device is a graphics tablet "puck" or similar device.
61 * @GDK_SOURCE_KEYBOARD: the device is a keyboard.
62 * @GDK_SOURCE_TOUCHSCREEN: the device is a direct-input touch device, such
63 * as a touchscreen or tablet. This device type has been added in 3.4.
64 * @GDK_SOURCE_TOUCHPAD: the device is an indirect touch device, such
65 * as a touchpad. This device type has been added in 3.4.
67 * An enumeration describing the type of an input device in general terms.
76 GDK_SOURCE_TOUCHSCREEN,
82 * @GDK_MODE_DISABLED: the device is disabled and will not report any events.
83 * @GDK_MODE_SCREEN: the device is enabled. The device's coordinate space
84 * maps to the entire screen.
85 * @GDK_MODE_WINDOW: the device is enabled. The device's coordinate space
86 * is mapped to a single window. The manner in which this window
87 * is chosen is undefined, but it will typically be the same
88 * way in which the focus window for key events is determined.
90 * An enumeration that describes the mode of an input device.
101 * @GDK_AXIS_IGNORE: the axis is ignored.
102 * @GDK_AXIS_X: the axis is used as the x axis.
103 * @GDK_AXIS_Y: the axis is used as the y axis.
104 * @GDK_AXIS_PRESSURE: the axis is used for pressure information.
105 * @GDK_AXIS_XTILT: the axis is used for x tilt information.
106 * @GDK_AXIS_YTILT: the axis is used for y tilt information.
107 * @GDK_AXIS_WHEEL: the axis is used for wheel information.
108 * @GDK_AXIS_LAST: a constant equal to the numerically highest axis value.
110 * An enumeration describing the way in which a device
111 * axis (valuator) maps onto the predefined valuator
112 * types that GTK+ understands.
128 * @GDK_DEVICE_TYPE_MASTER: Device is a master (or virtual) device. There will
129 * be an associated focus indicator on the screen.
130 * @GDK_DEVICE_TYPE_SLAVE: Device is a slave (or physical) device.
131 * @GDK_DEVICE_TYPE_FLOATING: Device is a physical device, currently not attached to
132 * any virtual device.
134 * Indicates the device type. See <link linkend="GdkDeviceManager.description">above</link>
135 * for more information about the meaning of these device types.
