XChangeDeviceDontPropagateList(3)				    X FUNCTIONS 				 XChangeDeviceDontPropagateList(3)

NAME

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

SYNTAX

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

       XEventClass *XGetDeviceDontPropagateList(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  sup-
       pressed,  a BadClass error will result.	Events that can be suppressed include DeviceKeyPress, DeviceKeyRelease, DeviceButtonPress, Device-
       ButtonRelease, 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  XOpenInputDe-
		   vice.   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 gener-
		   ate this error.

       BadWindow   An invalid window id was specified.

       BadClass    An invalid event class was specified.
