## Member Function Documentation

bool Gdk::Device::get_axis | ( | double& | axes,
|  | AxisUse | use,
|  | double& | value
| ) | const

  | Interprets an array of double as axis values for a given device, and locates the value in the array for a given axis use. Parameters:
  axes | Pointer to an array of axes.
  use | The use to look for.
  value | Location to store the found value.
Returns: `true` if the given axis use was found, otherwise `false`.

bool Gdk::Device::get_history | ( | const Glib::RefPtr<Window>& | window,
|  | guint32 | start,
|  | guint32 | stop,
|  | GdkTimeCoord **& | events,
|  | int& | 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.) Parameters:
  window | The window with respect to which which the event coordinates will be reported.
  start | Starting timestamp for range of events to return.
  stop | Ending timestamp for the range of events to return.
  events | Location to store a newly-allocated array of Gdk::TimeCoord, or `0`.
  n_events | Location to store the length of events , or `0`.
Returns: `true` if the windowing system supports motion history and at least one event was found.
