display
       Specifies the connection to the X server\&.

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

event_list
       Specifies a pointer to a list of event classes\&.
.fi

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

.SH "DESCRIPTION"
.sp
.if n \{\
.RS 4
.\}
.nf
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\&.
.fi
.if n \{\
.RE
.\}
.sp
.if n \{\
.RS 4
.\}
.nf
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\&.
.fi
.if n \{\
.RE
.\}
.sp
.if n \{\
.RS 4
.\}
.nf
XChangeDeviceDontPropagateList can generate a BadDevice,
BadClass, or BadValue error\&.
.fi
.if n \{\
.RE
.\}
.sp
.if n \{\
.RS 4
.\}
.nf
The XGetDeviceDontPropagateList request queries the list of
events that should not be propagated to ancestors of the event
window\&.
.fi
.if n \{\
.RE
.\}
.sp
.if n \{\
.RS 4
.\}
.nf
XGetDeviceDontPropagateList can generate a BadClass or
BadWindow error\&.
.fi
.if n \{\
.RE
.\}
.SH "DIAGNOSTICS"
.sp
.if n \{\
.RS 4
.\}
.nf
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\&.
.fi
.if n \{\
.RE
.\}
.sp
.if n \{\
.RS 4
.\}
.nf
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\*(Aqs 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\&.
