Under X, the support for multiple input devices is done + * through the <firstterm>XInput 2</firstterm> extension, which also supports + * additional features such as sub-pixel positioning information and additional + * device-dependent information. + * @Title: GdkDeviceManager + * @See_also: #GdkDevice, #GdkEvent, gdk_enable_multidevice() + * + * By default, GDK supports the traditional single keyboard/pointer input scheme (Plus additional + * special input devices such as tablets. In short, backwards compatible with 2.X). Since version 3.0, + * if gdk_enable_multidevice() is called before gdk_display_open() and the platform supports it, GDK + * will be aware of multiple keyboard/pointer pairs interacting simultaneously with the user interface. + * + * Conceptually, in multidevice mode there are 2 device types, virtual devices (or master devices) + * are represented by the pointer cursors and keyboard foci that are seen on the screen. physical + * devices (or slave devices) represent the hardware that is controlling the virtual devices, and + * thus has no visible cursor on the screen. + * + * Virtual devices are always paired, there is a keyboard device for every pointer device, + * associations between devices may be inspected through gdk_device_get_associated_device(). + * + * There may be several virtual devices, and several physical devices could be controlling each of + * these virtual devices. Physical devices may also be "floating", which means they are not attached + * to any virtual device. + * + * By default, GDK will automatically listen for events coming from all master devices, setting the + * #GdkDevice for all events coming from input devices + * <footnote> + * Events containing device information are #GDK_MOTION_NOTIFY, #GDK_BUTTON_PRESS, #GDK_2BUTTON_PRESS, + * #GDK_3BUTTON_PRESS, #GDK_BUTTON_RELEASE, #GDK_SCROLL, #GDK_KEY_PRESS, #GDK_KEY_RELEASE, + * #GDK_ENTER_NOTIFY, #GDK_LEAVE_NOTIFY, #GDK_FOCUS_CHANGE, #GDK_PROXIMITY_IN, #GDK_PROXIMITY_OUT, + * #GDK_DRAG_ENTER, #GDK_DRAG_LEAVE, #GDK_DRAG_MOTION, #GDK_DRAG_STATUS, #GDK_DROP_START, + * #GDK_DROP_FINISHED and #GDK_GRAB_BROKEN. + * </footnote> + * , although gdk_window_set_support_multidevice() has to be called on #GdkWindow<!-- --> in order to + * support additional features of multiple pointer interaction, such as multiple, per-device enter/leave + * events. The default setting will emit just one enter/leave event pair for all devices on the window. + * See gdk_window_set_support_multidevice() documentation for more information. + * + * In order to listen for events coming from other than a virtual device, gdk_window_set_device_events() + * must be called. Generally, this function can be used to modify the event mask for any given device. + * + * Input devices may also provide additional information besides X/Y. For example, graphics tablets may + * also provide pressure and X/Y tilt information. This information is device-dependent, and may be + * queried through gdk_device_get_axis(). In multidevice mode, virtual devices will change axes in order + * to always represent the physical device that is routing events through it. Whenever the physical device + * changes, the #GdkDevice:n-axes property will be notified, and gdk_device_list_axes() will return the + * new device axes. + * + * Devices may also have associated <firstterm>keys</firstterm> or macro buttons.
