                    guint *keyval,
                    GdkModifierType *modifiers);

If index has a valid keyval, this function will fill in keyval and modifiers with the keyval settings.

gdk_device_set_axis_use ()

void
gdk_device_set_axis_use (GdkDevice *device,
                         guint index_,

GdkAxisUse
gdk_device_get_axis_use (GdkDevice *device,
                         guint index);

Returns the axis use for index .

Since: 2.22

gdk_device_get_core_pointer ()

GdkDevice *
gdk_device_get_core_pointer (void);

Returns the core pointer device for the default display.

gdk_device_get_state ()

void
gdk_device_get_state (GdkDevice *device,
                      GdkWindow *window,
                      gdouble *axes,
                      GdkModifierType *mask);

Gets the current state of a device.

gdk_device_get_history ()

gboolean
gdk_device_get_history (GdkDevice *device,
                        GdkWindow *window,
                        guint32 start,
                        guint32 stop,
                        GdkTimeCoord ***events,
                        gint *n_events);

Obtains the motion history for a device; given a starting and ending timestamp, return all events in the motion history for the device in the given range of time. Some windowing systems do not support motion history, in which case, FALSE will be returned. (This is not distinguishable from the case where motion history is supported and no events were found.)

gdk_device_free_history ()

void
gdk_device_free_history (GdkTimeCoord **events,
                         gint n_events);

Frees an array of GdkTimeCoord that was returned by gdk_device_get_history().

gdk_device_get_axis ()

gboolean
gdk_device_get_axis (GdkDevice *device,
                     gdouble *axes,
                     GdkAxisUse use,
                     gdouble *value);

Interprets an array of double as axis values for a given device, and locates the value in the array for a given axis use.

gdk_device_get_n_axes ()

gint
gdk_device_get_n_axes (GdkDevice *device);

Gets the number of axes of a device.
