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
       arguments 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.
