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

count Specifies the number of event classes in the

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.
