NAME

  XChangeDeviceDontPropagateList, XGetDeviceDontPropagateList - query or
  change the dont-propagate-list for extension devices


SYNOPSIS

  XChangeDeviceDontPropagateList(display, window, count, event_list, mode)
	  Display *display;
	  Window *window;
	  int *count;
	  XEventClass *event_list;
	  int mode;

  XEventClass *XGetDeviceDontPropagateList(display, window, count)
	  Display *display;
	  Window *window;
	  int *count;


ARGUMENTS

  display
      Specifies the connection to the X server.

  window
      Specifies the window whose dont-propagate-list is to be queried or
      modified.

  event_list
      Specifies a pointer to a list of event classes.

  mode
      Specifies the mode. You can pass AddToList, or DeleteFromList.

  count
      Specifies the number of event classes in the list.


DESCRIPTION

  The XChangeDeviceDontPropagateList request modifies the list of events that
  should not be propagated to ancestors of the event window. This request
  allows extension events to be added to or deleted from that list.  By
  default, all events are propagated to ancestor windows. Once modified, the
  list remains modified for the life of the window. Events are not removed
  from the list because the client that added them has terminated.

  Suppression of event propagation is not allowed for all input extension
  events.  If a specified event class is one that cannot be suppressed, a
  BadClass error will result.  Events that can be suppressed include
  DeviceKeyPress, DeviceKeyRelease, DeviceButtonPress, DeviceButtonRelease,
  DeviceMotionNotify, ProximityIn, and ProximityOut.

  XChangeDeviceDontPropagateList can generate a BadDevice, BadClass, or
  BadValue error.

  The XGetDeviceDontPropagateList request queries the list of events that
  should not be propagated to ancestors of the event window.

  XGetDeviceDontPropagateList can generate a BadClass or BadWindow error.


DIAGNOSTICS

  BadDevice
	  An invalid device was specified.  The specified device does not
	  exist or has not been opened by this client via XOpenInputDevice.
	  This error may also occur if some other client has caused the
	  specified device to become the X keyboard or X pointer device via
	  the XChangeKeyboardDevice or XChangePointerDevice requests.

  BadValue
	  Some numeric value falls outside the range of values accepted by
	  the request. Unless a specific range is specified for an argument,
	  the full range defined by the argument's type is accepted.  Any
	  argument defined as a set of alternatives can generate this error.

  BadWindow
	  An invalid window id was specified.

  BadClass
	  An invalid event class was specified.
