display Specifies the connection to the X server.
window Specifies the window whose dont-propagate-list
is to be queried or modified.

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.
X Version 11 Release 6.4 1
XChangeDeviceDontPropagateLXsXChangeDeviceDontPropagateList(3X11)
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 speci-
fied 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 spe-
cific 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.
