NAME

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

SYNOPSIS

       #include <X11/extensions/XInput.h>

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

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

       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.
